1 Introduction

Due to the Covid-19 pandemic, many organizations converted to working from home (WFH) arrangements to comply with regulatory requirements, protect their employees’ health, and remain productive (e.g., Alipour et al. 2020). Barrero et al. (2021), among others, find that WFH is associated with positive consequences for employees, employers, and society at large, suggesting that WFH is likely to continue in the future. However, the shift to WFH poses severe challenges for organizations’ management control (MC). In particular, WFH likely reduces the effectiveness of MCs to steer employees toward taking actions that are consistent with organizational objectives. For example, under WFH conditions, employee actions are less observable, and the use of direct monitoring is limited. We analyze how the Covid-19 pandemic and the corresponding shift toward WFH shapes the design of MCs and, in turn, explore the role of MCs in explaining the association between WFH and employee outcomes such as working day structure and job focus.

Literature in psychology and management documents the benefits and costs associated with WFH. For instance, Gajendran and Harrison (2007) and Martin and MacDonnell (2012) suggest that WFH is associated with an increase in job satisfaction and organizational commitment. De Menezes and Kelliher (2011) and Bloom et al. (2015) show that WFH is associated with higher organizational performance. In contrast, WFH intermingles employees’ work-life and private-life, potentially resulting in mental problems such as stress (Alipour et al. 2020). Due to the physical separation from the workplace, the supervisor, and the colleagues, WFH may foster employees’ professional isolation (Golden et al. 2008).

Our study examines the design of MCs and the associated employee outcomes under WFH conditions. The Covid-19 pandemic and the corresponding shift toward WFH establish physically dispersed working environments. Such working environments amplify control problems within organizations and thus pose several challenges to the design of MCs. First, under WFH conditions, employees’ actions are less observable, limiting the possibilities for direct monitoring (Greer and Payne 2014; Allen et al. 2015) and potentially increasing the likelihood of mistakes and shirking. Second, WFH hampers the information exchange between employees and their supervisors as well as among employees. While the former reduces a supervisor’s effectiveness in providing direction and support (Bonet and Salvador 2017), the latter leads to less and more effortful communication (Gajendran and Harrison 2007; Lill 2020). Third, the professional isolation caused by WFH diminishes employee motivation and may lead to adverse job performance and increased turnover (Golden et al. 2008).

Organizations use their MCs to ensure that employees’ behaviors and decisions are consistent with the organization’s strategies and objectives (Anthony and Govindarajan 2004; Merchant and Van der Stede 2017), ultimately attaining fit and enhanced performance (Chenhall 2003). Generally, organizations select from a set of MC practices such as action, result, personnel, and cultural controls (Merchant and Van der Stede 2017). In the main analysis, we investigate how organizations adjust their MCs due to the Covid-19 pandemic and the associated shift toward WFH. During the pandemic, organizations are more likely to adapt action controls, as the associated control practices such as standardization, pre-action reviews, and planning participation are more easily adjusted in the short-term. Thus, we expect that organizations strengthen their action controls to mitigate the amplified control problems resulting from WFH conditions.

Relying on data from a survey distributed among 2855 employees without supervisory function in a large international multi-divisional service firm from March until April 2021, we find support for the predictions. First, the firm experienced a significant increase in WFH: On average, WFH has increased from 5 h per week in 2019 to 27 h per week in 2021. Second, we provide evidence that WFH is associated with amplified firm control problems. We find that, under WFH conditions, supervisors lack observability of employees’ actions; socialization processes are less prevalent under WFH conditions, arguably increasing social isolation and thus decreasing organizational identification and employee motivation. Third, we provide evidence of strengthened action controls. We find that supervisors more strongly standardize tasks of employees working from home and that supervisors more strongly involve these employees in their strategic planning. A mechanism analysis suggests that these results are explained by the supervisor’s lack of observability of employees’ actions rather than the hampered communication or socialization under WFH conditions.

In an additional analysis, we examine the association between WFH and employee outcomes (such as meeting hours and employee focus) and the moderating role of MCs. This analysis provides further insights into the benefits and costs of action controls. We document that the number of hours employees spend in meetings is significantly higher in 2021 as compared to 2019, which is partly explained by the strong increase in WFH from 2019 to 2021. Interestingly, this association is only statistically significant in the subsample of weak action controls. This finding suggests that strong action controls reduce the necessity for time-consuming meetings. In addition, we find that employees are better able to focus on their job in 2021 as compared to 2019 when they experienced a strong increase in WFH.

The study contributes to the literature in three ways. First, we contribute to the literature by investigating how WFH is associated with the design of MCs. The Covid-19 pandemic pushed organizations toward WFH. As WFH is likely to stick in the future as a new way of working (Barrero et al. 2021), there is an increased interest in the association between WFH and MCs. We show that WFH amplifies organizations’ control problems of lack of direction, lack of motivation, and personal limitations, suggesting that organizations consider the role of WFH in setting up their MCs.

Second, physically dispersed teams are ubiquitous in modern organizations (Bonet and Salvador 2017). For example, professional service firms or IT companies often employ teams where team members work at different places. Such arrangements pose challenges to collaboration and communication among team members and supervisors (Dulebohn and Hoch 2017). We study how supervisors design their MCs in situations where employees are physically dispersed. We thereby add to the literature investigating organizational structure as an important contingency factor for the effectiveness and design of MCs (e.g., Abernethy et al. 2004; Gerdin 2005; Kristensen and Israelsen 2014).

Third, we examine how WFH in conjunction with MCs is associated with employee outcomes. Prior studies address the consequences of WFH on individual and organizational outcomes such as job satisfaction or turnover (Gajendran and Harrison 2007; De Menezes and Kelliher 2011), productivity (e.g., Bloom et al. 2015), and work patterns (e.g., Gibbs et al. 2022). For example, Bloom et al. (2015) investigate the effects of WFH on productivity, such as calls per minute for employees of a Chinese travel agency. We investigate how the design of MCs moderates the association between WFH and employee outcomes such as meeting hours and employee focus.

The remainder of the paper is organized as follows. Section 2 reviews previous literature and develops the hypothesis. Section 3 presents the empirical study, including data, sample, and variable measurement. Section 4 reports the main findings, the robustness checks, and additional analysis. Section 5 concludes.

2 Literature and hypothesis development

2.1 Covid-19 and WFH

The Covid-19 pandemic had severe impacts on the economic activity of firms. In the short-term, the decrease in sales and liquidity led to a strained financial situation of numerous German firms (Bundesbank 2021). For example, for a representative sample of German firms, Bischof et al. (2020) find that approximately 60% of firms experienced a sales decrease of more than 10% due to the pandemic. Besides using governmental aid programs, firms took cost-cutting measures, limited their cash outflows, and increased their demand for loans (Bischof et al. 2022; Kfw 2021). Bloom et al. (2021) document a significant drop in business due to the Covid-19 pandemic for a broad sample of US firms.

Besides, governments all around the globe imposed non-pharmaceutical interventions such as obligatory WFH to reduce the spread of the virus. Due to the pandemic, WFH has increased substantially. In Germany, 34% of employees worked partly or entirely from home in April 2020 compared to only 12% of employees before the pandemic (Schröder et al. 2020; DIW Berlin 2016). In the US, the percentage of paid full days worked from home rose from five percent to over 60 percent in May 2020 and remained between 50 and 43 percent in 2021 (Barrero et al. 2021).

Literature documents various consequences of WFH. At the organizational level, WFH enables organizations to attract a larger and more diverse talent pool (Eversole et al. 2012), reduce absenteeism (De Menezes and Kelliher 2011), and lower real estate costs (Perez et al. 2002). However, WFH poses challenges regarding the provision of an effective work environment and in terms of compliance issues related to data protection (McKinsey 2020); and legal issues such as income taxation, the recording of hours worked, and insurances in case of work accidents (Forbes 2021).

At the individual level, positive effects of WFH include increased organizational commitment and job satisfaction (Gajendran and Harrison 2007; Martin and MacDonnell 2012). For example, WFH increases employees’ flexibility when and how work is done. Employees save commuting time and stay closer to their families, which improves work-life balance (Brownson 2004). WFH also allows employees to escape undesirable features of the office workplace, such as noise or interruptions by colleagues (Sewell and Taskin 2015). However, WFH diminishes employees’ clear distinction between work and private-life (Ashforth et al. 2000; Raghuram and Wiesenfeld 2004), potentially causing mental problems like stress (Alipour et al. 2020). Related, the physical separation from the workplace and their co-workers can increase employees’ perceived isolation (Golden et al. 2008). And finally, the missing salience of organizational facilities and symbols likely reduces the employees’ identification with the organization (e.g., Illgems and Verbeke 2004; Sardeshmukh et al. 2012).

Several studies investigate how WFH affects employee productivity. Angelici and Profeta (2020) document in a field experiment that granting employees time and space flexibility increases their productivity. Bloom et al. (2015) conduct a WFH field experiment with employees from a Chinese travel-agency call center; they find that WFH increases productivity by 13%. In contrast, relying on observational data, Gibbs et al. (2022) find that employee productivity fell for a sample of 10,000 Indian IT professionals who shifted abruptly to WFH during the Covid-19 pandemic.

The literature also investigates the changes in work patterns when employees shift to WFH. Teevan et al. (2020) and Yang et al. (2022), using detailed communication data of US Microsoft employees, document an increase in the number of meetings and meeting participants. Employees’ communication under WFH relies on modern telecommunication devices. The devices alter the amount and quality of exchanged information and the way co-workers communicate and coordinate among each other (e.g., Workman 2005; Gajendran and Harrison 2007), potentially resulting in higher communication costs (Gibbs et al. 2022; Yang et al. 2022). At the same time, WFH increases total working hours (DeFilippis et al. 2020) but decreases uninterrupted working hours (Gibbs et al. 2022). What remains open is how the design of MCs moderates the association between WFH and employee outcomes.

2.2 MCs

Management Control (MC) refers to all procedures, methods, and devices to ensure that employees’ behaviors and decisions are consistent with the organization’s strategies and objectives (Anthony and Govindarajan 2004). The set of applied MC practices forms the organization’s MC system. The organization establishes MCs because employees may not act in the best interest of the organization (Jensen and Meckling 1976). According to Merchant and Van der Stede (2017), control problems emerge because employees do not know what the company expects from them (i.e., lack of direction); employees pursue their own interests that do not coincide with the organizational objectives (i.e., lack of motivation); employees do not have the necessary resources and skills to perform the tasks assigned to them (i.e., personal limitations).

In addressing the control problems, the organization chooses from diverse MC practices. Merchant and Van der Stede (2017) classify MC practices according to the object of control. Within this framework, the organization’s MC practices focus on the actions taken by employees (action control), the results produced by employees (result control), the values and norms shared among employees (cultural control), and the type of people employed (personnel controls).

In this study, we focus on the design of action controls under WFH conditions caused by the Covid-19 pandemic. Action controls represent the “most direct form of management control” (Merchant and Van der Stede 2017, p.86) and ensure that employees perform specific actions that contribute to the organization’s success. To that end, action controls restrict employees’ discretion by specifying boundaries to acceptable behavior or by implementing formal approval procedures (Simons 1995). Action controls are effective when the employee knows the actions required to obtain a particular outcome, and control is achieved by monitoring adherence to standardized rules and procedures (Ouchi 1977).

The focus on action controls is motivated by the MCs’ adaptability. The pandemic-related push toward WFH changes organizations’ external environment, requiring an adaptation of organizations’ MCs to attain fit and enhanced performance (Chenhall 2003). However, organizations might not be able to adjust all MC practices in the short-term as an organization’s MC design focuses on efficiency rather than adaptability (Otley 1994). As implementing result (e.g., performance measurement), personnel (e.g., employee selection), and cultural controls (e.g., codes of conduct) requires large organizational effort, these MCs are not likely to be adjusted in the short-term. We argue that such constraints are weaker for action controls.

Specifically, we focus on the action controls: (1) Standardization; (2) Planning participation; and (3) Pre-action reviews. Standardization refers to guidelines and procedures that specify the means of the conducted work activities (Daft and Macintosh 1984). Standardization addresses a lack of direction as well as personal limitations because employees can follow guidelines and apply pre-determined procedures. Planning participation refers to the involvement of employees in strategic planning processes and the pre-determination of activities. The participation of employees in the planning process aims to achieve goal congruence (Coch and French Jr 1948; Nutt 1989) because employees will be familiar with the organization’s objectives, enabling employees to focus on organizational goals (Ketokivi and Castaner 2004). Thus, planning participation provides direction to employees and addresses motivational concerns. With pre-action reviews, supervisors scrutinize their employees’ action plans such that supervisors can approve or disapprove certain actions or ask for modifications and re-adjustments. Pre-action reviews guide or restrict proposed activities (Merchant and Stede, 2017), providing direction and resolving personal limitations.

According to contingency theory (Otley 1980), an organization selects the design of its MCs such that the controls match the internal and external environment. In other words, an organization trades off the benefits and costs of the MC practices in the respective context to implement an effective MC system. Prior work examines the choice and effectiveness of MCs with regard to contingency factors such as strategy (e.g., Bisbe and Otley 2004; Widener 2007; Bedford et al. 2016), organizational structure (e.g., Abernethy et al. 2004; Gerdin 2005; Kristensen and Israelsen 2014), culture (e.g., Harrison and McKinnon 1999; Heinicke et al. 2016; Malmi et al. 2020), and environmental uncertainty (e.g., Grabner et al. 2018; Gerdin et al. 2019). Below, we elaborate on the benefits and costs of MC practices under WFH conditions.

2.3 Hypothesis development

Given an organization’s control problem, the organization trades off the benefit and cost of the MC practices when designing its MC system (Milgrom and Roberts 1992; Roberts 2004). For action controls, the benefit relates to the mitigated control problems. The cost relates to administrative resources (e.g., the salaries of supervisors or employees who set up and enforce action controls) and the investments to install monitoring devices.

We expect that WFH amplifies the organization’s control problem and thus increases the benefit of action controls. Generally, WFH involves a lack of observability, professional isolation, and a hampered information exchange. First, the lack of observability of an employee’s actions limits the supervisor’s possibility for direct monitoring (Felstead et al. 2003; Greer and Payne 2014; Allen et al. 2015), increasing the probability of mistakes and shirking. Related, the physical separation of the employee from their co-workers reduces the scope for beneficial mutual monitoring (Arya et al. 1997), reducing the effectiveness of alternative means to address the control problem. Second, due to the lack of face-to-face interaction and informal exchange with co-workers, the employee feels professionally isolated, out of touch with their peers (Illgems and Verbeke 2004; Lill 2020), and suffers motivational challenges, resulting in increased turnover intention (Golden et al. 2008). Third, the information exchange between the employee and the supervisor is more challenging, reducing the supervisor’s opportunity to provide guidance and mentoring (Bonet and Salvador 2017). The hampered information exchange is potentially mitigated by the use of modern communication technologies such as instant messaging or video communication (Yang et al., 2022).

The cost of implementing action controls such as standardization, planning participation, and pre-action reviews is arguably similar under WFH conditions compared to an office working environment. Thus, we expect that the organization strengthens the use of action controls under WFH conditions.Footnote 1 Consequently, we state:

H1: Action controls are stronger when employees work from home.

3 Empirical study

3.1 Sample and data collection

We test the prediction using a survey sent to employees of a large international multi-divisional service firm. The research site represents a promising setting for two reasons: First, the firm’s divisions offer a large and diverse spectrum of services, which requires different MCs. Thus, the research site allows us to examine the use and effectiveness of MC practices for a broad range of business types, even though the study is conducted within a single firm. Second, the firm’s divisions differ in the extent to which they enable the use of WFH (for example, due to data security restrictions or the extent of on-site customer services). Thus, employees face variations in the strength of the WFH shock due to the Covid-19 pandemic (i.e., the increase in WFH hours per week).Footnote 2 Interviews with the firm's management revealed that, broadly stated, the firm’s businesses were only mildly affected by the pandemic. That is, neither sales declined substantially nor was there a significant change in the employees’ tasks due to the pandemic.

To inform the development of the survey, we first conducted interviews with the head of management accounting to gather a general understanding of the MCs employees are exposed to in their daily work. We designed the survey to reflect the insights from the interview. The survey consists of four parts: Questions on (1) the prevalence of WFH, (2) the use of MC practices according to the framework by Merchant and Stede (2017), (3) employee outcomes, and (4) control variables. Questions cover two periods: Before and after the first Covid-19 lockdown period (i.e., in 2019 and 2021, respectively).Footnote 3

We distributed the questionnaire via an online survey in March and April 2021 among 2855 employees without supervisory function in seven divisions of the firm and reached a response rate of roughly 60%. To guarantee anonymity, we used the custodian approach (Vogel 2018), i.e., one employee from the HR department of each division distributed the survey to the respondents. After cleaning the dataset, the final sample contains 2576 employee-year observations for the years 2019 and 2021. Table 1 presents the sample selection procedure.

Table 1 Sample Selection

Since we collect the variables from a survey, the results could be exposed to the common method bias. To reduce this concern, we took established procedural steps ex-ante, such as avoiding ambiguity in the survey questions, guaranteeing employees’ anonymity by the custodian approach, and providing respondents with a cover story that separates the key variables. Furthermore, we conduct a Harman’s one factor test by applying an unrotated principal components analysis to assess common method bias (Bedford and Malmi 2015; Chin 2010). The first factor explains 30.6% of the variance, indicating no evidence for the presence of a common method bias (Podsakoff and Organ 1986).

To reduce the concern of a non-response bias, we provided respondents with a comfortable survey setting by allowing them to interrupt the survey at any time and continue later. Additionally, we promoted survey participation via the custodians. To test whether the results are subject to a non-response bias, despite the implemented measures, we rely on the extrapolations approach suggested by Armstrong and Overton (1977) and compare observations from early and late responders using univariate ANOVAs. We find no statistically significant differences (i.e., p > 0.10) in the main dependent and independent variables when comparing data of respondents who completed the survey before and after we have sent out a reminder (i.e., April 13th 2021).

3.2 Regression model

To examine Hypothesis H1 that WFH is associated with stronger action controls, we run the following regression model:

$${\mathbf{MC}}_{it} = \beta_{0} + \gamma WFH_{it} + {\mathbf{\theta Tenure}}_{i} + \tau Teamsize_{i} + \eta_{k} + \varepsilon_{it} ,$$
(1)

where i captures the employee, t reflects the year, and k reflects the employee’s division of the firm. \({\mathbf{MC}}\) is a vector capturing aggregate action control and the single action control practices standardization, planning participation, and pre-action reviews. \(WFH\) captures the employee’s exposure to WFH. \({\mathbf{Tenure}}\) is a vector capturing three types of employee tenure measures. \(Teamsize\) is the size of the team or department the employee is working in. \(\eta_{k}\) captures division fixed effects. The regression model is estimated by ordinary least squares (OLS) with robust standard errors clustered at the employee level. Following Hypothesis H1, we expect \(\gamma\) to be positive for each measure of action control, suggesting that WFH is associated with stronger action controls.

3.3 Variable measurement

We collected the main variables through reflective and formative multi-item constructs measured on a 7-point Likert scale: 1 for “very small extent” and 7 for “very high extent.” Wherever possible, we rely on pre-established measures from literature. When there is no appropriate construct available in the literature, we suggest a corresponding measure while relying on similar established constructs and definitions from previous work.

Since the research site predominantly employs native German employees, we translated the survey into German to address potential language barriers. To guarantee validity, we asked an academic who is not affiliated to this study to back-translate the survey into English. Before distributing the survey, we collected feedback from academics as well as practitioners. Based on this feedback, we conducted minor verbal adjustments to make sure that the respondents understand the survey questions.

3.3.1 Main variables

We capture WFH by the number of hours employees work from home. In particular, WFH is the natural logarithm of the number of hours worked from home per week, as indicated by the respondent for the years 2019 and 2021. We acknowledge that WFH reflects the realized WFH time and not necessarily the intended WFH time.

We capture action controls in three different types: (1) standardization, (2) planning participation, and (3) pre-action reviews. The constructs are based on Bedford and Malmi (2015). Standard is a three-item reflective construct, capturing to what extent there are rules and procedures in place that specify how work activities have to be conducted. PlanPart captures to what extent employees are involved in strategic planning processes. ActRev is a two-item formative construct, capturing to what extent there are processes of scrutinization and authorization before an activity is performed by an employee. The final variables represent the latent variable scores obtained from construct validation of all items related to the single constructs.Footnote 4

We assume that the supervisor’s use of action controls (ActCtrl) is a higher-order formative construct that is an aggregate of the three lower-order constructs Standard, PlanPart, and ActRev. We determine ActCtrl by taking the latent variable scores obtained from construct validation of the constructs Standard, PlanPart, and ActRev. We report the survey questions and response scales in Appendix 1 and perform construct validity analyses in Appendix 2.Footnote 5

3.3.2 Control variables

We capture the size of the control problem by three variables reflecting task programmability, ease of communication, and socialization. Task programmability (TaskProg) is the extent that supervisors are able to observe employees’ actions and to anticipate action-outcome relations. TaskProg is measured as a three-item reflective construct used by Bedford and Malmi (2015). The final variable is the latent variable score obtained from construct validation of all items related to task programmability in the respective year as indicated by the respondent. Communication (Comm) accounts for the difficulty of the information exchange. Comm is a score capturing the extent to which informal communication is used in passing information up and down the hierarchy in the respective year as indicated by the respondent. The variable Social is measured by a three-item formative construct based on Bedford and Malmi (2015) and captures to what extent there are processes in place that emphasize organizational values and norms. The final variable is the latent variable score obtained from construct validation of all items related to socialization in the respective year indicated by the respondent.

We control for different types of employee tenure to account for potential differences in the use of MCs related to employee experience or the trust between supervisors and employees. TenureBoss captures the natural logarithm of the midpoint of the range indicated as tenure with the current supervisor in years. TenurePos captures the natural logarithm of the midpoint of the range indicated as tenure in the current position in years. TenureFirm captures the natural logarithm of the midpoint of the range indicated as tenure with the company in years.

We also control for the size of the team the employee is working in, which likely explains the effectiveness and thus use of MCs. Teamsize is measured as the natural logarithm of the total number of employees working in the same team or department. Finally, we add division fixed effects to account for potential differences in the applicability of MCs across the divisions at the research site.

4 Results

In this section, we present the regression results of the study. In Sect. 4.1, we report on the descriptive statistics. In Sect. 4.2, we elaborate upon the main findings related to Hypothesis H1, stating that WFH is associated with stronger action controls. In Sect. 4.3, we report on the mechanism driving Hypothesis H1. In Sect. 4.4, we report on an additional analysis that emphasizes the implications of the main findings. More specifically, we study how the shift toward WFH is associated with employee outcomes, such as employees’ working day structure and the extent to which employees focus on their job, and how the organization’s MC choice moderates the association between WFH and employee outcomes.

4.1 Descriptive statistics

Table 2 presents the descriptive statistics on the variables. In Panel A, we report on the full sample. In Panel B, we report on the change in the control problem from before (i.e., 2019) to during the pandemic (i.e., 2021). In Panel C, we compare the main variables for low and high WFH (i.e., we split the sample at the median of WFH).

Table 2 Descriptive Statistics

On average, employees work 16 h per week from home with a minimum of 0 h and a maximum of 50 h. The measures for action controls range between 1 and 7 with a mean of 3.9 for ActCtrl, 4.4 for Standard, 3.2 for PlanPart, and 3.9 for ActRev. Employees work for their current supervisor (in their current position) on average for 3.6 (5.6) years (TenureBoss, TenurePos) and they work for the firm for on average 6.9 years (TenureFirm). Teamsize ranges between 2 and 202 employees with a mean of 15.

Panel B shows the change in the control problem from before to during the pandemic. WFH has increased substantially from 5 h per week before the pandemic to 27 h per week during the pandemic (p-value < 0.01). We argue that—during the pandemic—employee actions are less observable; the information exchange between employees and their supervisors and colleagues is more difficult; the salience of social events that foster organizational identification and thus employees’ intrinsic motivation to work in the organization’s best interest is reduced. Consistently, we find a reduction in the extent to which supervisors can observe employees’ actions (TaskProg, p-value < 0.10). We also find a reduction in the extent to which informal communication is used to communicate along the hierarchy, but the difference is not statistically significant (Comm, p-value = 0.11). Finally, we find a statistically significant decrease in Social (p-value < 0.01), suggesting that the number of social events and programs has declined substantially from 2019 to 2021.

Panel C compares action controls for low and high WFH. We find that all action controls (i.e., Standard, PlanPart, ActRev) are stronger for high WFH than low WFH. The difference is statistically significant for Standard (p-value < 0.01), PlanPart (p-value < 0.01), and the aggregate measure of the action controls (ActCtrl, p-value < 0.01). However, we do not find a statistically significant difference for ActRev. While these comparisons are insightful, the bivariate nature does not account for further determinants of the use of MCs. We postpone a more detailed discussion of the association between WFH and action controls to the multiple regression analysis.Footnote 6

4.2 Main results

In Table 3, Panel A, we present the main findings of the OLS regression model related to Hypothesis H1. In Column (1), we operationalize action controls by the aggregate variable ActCtrl. In Columns (2) to (4), we operationalize action controls by the single constructs (i.e., Standard, PlanPart, and ActRev). We find a positive and statistically significant (p-value < 0.05) coefficient on WFH when using ActCtrl as the dependent variable. We also find a positive and statistically significant (p-value < 0.01) coefficient on WFH when using Standard and PlanPart as dependent variables. From 2019 to 2021, WFH has increased, on average, from 5 to 27 h. In terms of economic significance, an increase in WFH by 22 h is associated with an increase of 0.04 standard deviations in ActCtrl. The findings suggest that organizations strengthen action controls under WFH conditions, providing support for Hypothesis H1.

Table 3 OLS regressions on the association between WFH and the use of action controls (Hypothesis H1)

We do not find a statistically significant association between WFH and ActRev. This finding may be explained by the fact that action controls are not only beneficial because they address ensuing control problems, but their implementation is costly as they require the supervisor’s involvement. In particular, pre-action reviews are arguably more costly than standardizing processes. While the standardization of processes is associated with a one-time cost when the supervisor chooses the guidelines and procedures, pre-action reviews require more regular meetings and coordination between the supervisor and the employees.

Regarding the control variables, we find that employees’ tenure at the firm matters. For instance, we find a positive and statistically significant (p-value < 0.01) association between TenureFirm and PlanPart and we find a negative and statistically significant (p-value < 0.01) association between TenureFirm and ActRev. These findings suggest that supervisors more strongly rely on planning participation the longer the subordinate is working at the firm, while they rely less on pre-action reviews with subordinate tenure.

Since WFH significantly increased from 2019 to 2021 (see the descriptive statistics in Panel B of Table 2), the coefficient on WFH in Table 3 Panel A may (partly) capture the association between the pandemic and action controls (i.e., the change in action controls over time) rather than the association between WFH and action controls. For instance, supervisors may increase their use of action controls to account for the increase in uncertainty associated with the pandemic. To disentangle the underlying mechanism, we run two further analyses: (1) In Table 3 Panel B, we examine the association between the pandemic and action controls. In particular, we regress the measures of action controls on an indicator variable equal to 1 if the year is 2021, 0 for year 2019 (Post). (2) In Table 3 Panel C, we examine to what extent the pandemic and WFH is associated with action controls. More specifically, we regress the measures of action controls on Post and an indicator variable equal to 1 when the employee experienced a strong increase in WFH (i.e., an increase in WFH that is larger than the median increase of WFH), 0 otherwise (WFHChange). We add an interaction term between Post and WFHChange which captures whether there is a difference in action controls between employees who experienced a strong increase in WFH compared to those employees who experienced only a weak increase in WFH during compared to before the pandemic.

In Panel B, we find a positive and statistically significant coefficient on Post for all action control measures (p-value < 0.01 for ActCtrl, Standard, and PlanPart; p-value < 0.10 for ActRev), suggesting that action controls are stronger during compared to before the pandemic. In Panel C, we find a positive and statistically significant (p-value < 0.10) coefficient on the interaction between Post and WFHChange when using ActCtrl as the dependent variable. The results are consistent when using Standard as the dependent variable. For PlanPart and ActRev, we do not find a statistically significant coefficient on the interaction between Post and WFHChange (p-value > 0.10). The results in Panel C suggest that the increase in action controls during compared to before the pandemic is partly explained by those employees who experienced a significant increase in WFH. More generally, the findings suggest that action controls are stronger during the pandemic compared to before the pandemic and that the increase is partly explained by the shift toward WFH.

4.3 Mechanism analysis: the role of control problems

In this subsection, to explore the mechanism behind the positive association between WFH and action controls, we examine the role of the control problem in explaining the association. In Table 4, we examine whether the severity of the control problem moderates the association between WFH and action controls. We differentiate between three dimensions of the control problem enhanced by the shift toward WFH: the lack of employee-task observability (TaskProg, Column (1)), communication limitations (Comm, Column (2)), and the decline in socialization (Social, Column (3)). In Column (4), we run the entire model. We add the same control variables as in Model (1). The results are estimated by OLS and robust standard errors clustered at the employee level.

Table 4 Mechanism analysis: OLS regressions on the role of control problems

Consistent with the main findings in Table 3, we find a positive and statistically significant association between WFH and ActCtrl in all columns (p-value < 0.01 in columns (1), (3), and (4) and p-value < 0.05 in Column (2)). More importantly, we find a negative and statistically significant (p-value < 0.05) coefficient on the interaction term of WFH and TaskProg. This finding suggests that the supervisor less strongly relies on action controls when employees more often work from home and employees’ task is more observable, i.e., when the control problem is less severe. Related, we find a negative and statistically significant (p-value < 0.10) coefficient on the interaction term of WFH and Comm, suggesting that the supervisor less strongly relies on action controls when employees more often work from home and there is a larger information exchange between supervisor and employee. We do not find that socialization (Social) explains the association between WFH and action controls.

When we combine all dimensions of the control problem in one model in Column (4), we find that the lack of observability of employees’ tasks is the dominating explanation of the positive association between WFH and action controls. We obtain qualitatively similar results when using standardization, planning participation, or pre-action reviews as dependent variables (untabulated analyses).

4.4 Additional analysis

In the following, we explore the implications of the association between WFH and action controls and examine the association between WFH, action controls, and employee outcomes. We apply two measures of employee outcomes: (1) MeetHr captures the length of time employees spend in meetings per working day. It is measured as the average number of hours per day spent in meetings as indicated by the respondent.Footnote 7 Employees spend on average 1.19 h per day in meetings, while there is some variance (std. dev. = 1.55). (2) Focus captures the extent to which employees can focus on their job measured on the scale 0–25%–50%–75%–100%. On average, employees indicated that they can focus on their job by 81%, while there is strong variance (std. dev. = 19).

To examine the association between WFH, action controls, and employee outcomes, we run similar regression models as in Table 3: (1) We regress MeetHr (Focus) on WFH, thereby examining the association between WFH and the extent to which employees spend time in meetings (can focus on their job) (Panel A of Table 5). (2) Since WFH captures both, variance in employee outcomes with WFH and with the pandemic, we then regress MeetHr (Focus) on Post, indicating how the extent to which employees spend time in meetings (can focus on their job) differs during compared to before the pandemic (Panel B of Table 5). Post is an indicator variable equal to 1 if the year is 2021 and 0 for the year 2019. (3) We explore to what extent the change in employee outcomes is associated with a change in WFH rather than the pandemic itself (e.g., an increase in uncertainty) by regressing MeetHr (Focus) on Post and WFHChange as well as the interaction between Post and WFHChange (Panel C of Table 5). WFHChange is an indicator variable equal to 1 if the change in WFH is equal to or higher than the median change in WFH, 0 otherwise. WFHChange splits the sample into employees who experienced a strong increase in WFH as compared to those employees who experienced a weak increase in WFH. Thus, while Post captures the difference in employee outcomes during as compared to before the pandemic, the interaction between Post and WFHChange explores whether the difference between employee ouctomes during as compared to before the pandemic is at least partly explained by the shift toward WFH.

To explore the moderating role of action controls, we replicate the analysis, splitting the sample into weak and strong action control (at the median of ActCtrl). We add the same control variables as in regression model (1). The results are estimated by OLS and robust standard errors clustered at the employee level. Table 5 reports on the findings of this analysis.

Table 5 Additional analysis: OLS regressions on the association between WFH, the use of action controls, and employee outcomes

In Panel A, we find a positive and statistically significant (p-value < 0.01) coefficient on WFH when using MeetHr and Focus as dependent variables, respectively. These findings suggest that employees who more often work from home spend more time in meetings and can better focus on their job. Although the coefficient on WFH is slightly higher for the sample of weak action controls (Column (1c)) compared to the sample of strong action controls (Column (1b)) when using MeetHr as the dependent variable, there is no statistically significant difference between the coefficients (p-value = 0.11). Likewise, although the coefficient on WFH, when using Focus as the dependent variable, is slightly higher for the sample of weak action controls (Column (1c)) compared to the sample of strong action controls (Column (1b)), there is no statistically significant difference between the coefficients (p-value = 0.19).

In Panel B, we find a positive and statistically significant (p-value < 0.01) coefficient on Post when using MeetHr and Focus as dependent variables, respectively. This finding suggests that employees spend more time in meetings and can better focus on their job during compared to before the pandemic. Since the average number of overtime hours per week did not statistically significantly (p-value > 0.10) change during compared to before the pandemic (results untabulated), the remaining working hours per day likely decreased. When using MeetHr as the dependent variable, there is no statistically significant difference between the coefficients on WFH for the sample of weak action controls (Column (1c)) compared to the sample of strong action controls (Column (1b)) (p-value > 0.10). Likewise, although the coefficient on Post when using Focus as dependent variable is higher for the sample of weak action controls (Column (1c)) compared to the sample of strong action controls (Column (1b)), there is no statistically significant difference between the coefficients (p-value = 0.15).

In Panel C, we find a positive and statistically significant (p-value < 0.01) coefficient on Post when using MeetHr as dependent variable. More importantly, we find a positive and statistically significant (p-value < 0.05) coefficient on the interaction between Post and WFHChange in the full sample (column (1a)). This finding suggests that the increase in the average number of hours employees spend in meetings during compared to before the pandemic is partly explained by an increase in WFH. However, this is only true for employees exposed to weak action controls. That is, we find a positive and statistically significant (p-value < 0.05) coefficient on the interaction between Post and WFHChange for the sample with weak action controls (Column (1c)), whereas the coefficient is statistically insignificant for strong action controls (Column (1b)). This finding suggests that WFH increases the average number of hours employees spend in meetings per day for those employees exposed to weak action controls, but not for those employees exposed to strong action controls.

When using Focus as the dependent variable (columns (2a)–(2c)), we do not find a statistically significant (p-value > 0.10) coefficient on Post, suggesting that there is no difference in the extent to which employees can focus on their job during compared to before the pandemic. However, we find a positive and statistically significant (p-value < 0.01) coefficient on the interaction between Post and WFHChange. This finding suggests that employees are better able to focus on their job during compared to before the pandemic when they experience a stronger increase in WFH. We find that the coefficient on the interaction between Post and WFHChange is higher for the sample of weak action controls as compared to the sample of strong action controls, but the difference in coefficients is not statistically significant (p-value > 0.10).

Overall, the findings suggest that WFH induced by the pandemic increased the time employees spend in meetings, likely decreasing the remaining working hours per day, and increased the extent to which employees can focus on their job. Furthermore, we provide weak evidence for a moderating role of action controls. In particular, the findings suggest that, while strong action controls mitigate the number of hours working-from-home employees spend in meetings, they may also hinder the extent to which employees can focus on their job when working from home. The latter finding suggests that, by specifying boundaries to acceptable behavior or by implementing formal approval procedures (Simons 1995), strong action controls may limit the discretion of employees, interrupt employees’ task fulfillment, and ultimately reduce employees’ focus.

In terms of economic significance, in Panel C, average meeting hours per day increased by 31 min in 2021 as compared to 2019 for those employees who experienced a small or no increase in WFH (smaller than or equal to the median change in WFH). For those employees who experienced a strong increase in WFH (larger than the median change in WFH), average meeting hours per day increased by 50 min in 2021 as compared to 2019. Finally, we show that job focus for employees who experienced a small or no increase in WFH (smaller or equal to the median change in WFH) increases by 0.2% points. In comparison, it increases by 7% points for those employees who experienced a strong increase in WFH (larger than the median change in WFH).

5 Conclusion

This study examines how the Covid-19 pandemic and the corresponding shift toward WFH affects the design of MCs. The findings suggest that WFH amplifies control problems within organizations. In particular, employees indicate that their tasks are less observable, arguably decreasing their supervisor’s monitoring capabilities. Moreover, socialization processes that align employees with the organization’s objectives are less prevalent, arguably reducing organizational identification and employees’ motivation. We provide evidence that organizations adjust the action controls when employees more often work from home. Specifically, there is a higher standardization of processes and a stronger involvement in strategic planning processes for employees who work from home. These results are partly explained by the supervisor’s lack of observability of employees’ tasks.

We also examine the association between WFH and employee outcomes and the potentially moderating role of MC practices. We document that the number of hours employees spend in meetings is significantly higher in 2021 as compared to 2019, which is partly explained by the strong increase in WFH from 2019 to 2021. Interestingly, this association is only statistically significant in the subsample of weak action controls. Thus, strong action controls seem to reduce the necessity for time-consuming meetings. In addition, we find that employees can better focus on their job in 2021 as compared to 2019 when they experienced a strong increase in WFH. Overall, the study adds to the literature by exploring the association between WFH, MCs, and employee outcomes.

The study is subject to limitations. First, the design of this study does not allow to draw causal inferences on the effect of WFH on the use of action controls. However, we provide first evidence that there is a positive association between WFH and action controls. Second, we focus on action controls rather than exploring the full set of MC practices that is available to supervisors, including result controls, personnel controls, cultural controls, and the combination thereof. We focus the analysis on action controls because of the organization’s ability to adjust action controls in the short-term, whereas adjusting result, personnel, and cultural controls, respectively, is arguably more time-consuming. Future research may investigate mid- or long-term adjustments in a firm’s MC elements (including result, personnel, and cultural controls). We also investigate action control practices as a package rather than a system of interrelated practices. According to the systems approach of contingency theory (Drazin and Van de Ven 1985), organizations assure internally consistent MCs, implying interdependent MC practices (Grabner and Moers 2013). Future research may investigate potential complementary or substitute relations between the separate elements of action control. Third, we ask respondents to answer questions related to the years 2019 and 2021 at one point in time, potentially raising a memory bias. Future research may examine the long-term consequences of WFH on the use of MC practices.
