A meta‐analysis of sleep and work performance: An examination of moderators and mediators

The present study utilizes meta‐analytic techniques to examine the literature on sleep and work performance. In line with previous meta‐analytic research, results indicate that sleep and work performance have a positive relationship. However, more importantly, results from moderator analyses reveal that the type of sleep measurement (sleep quantity and sleep quality), work performance measurement (task performance, organizational citizenship behavior, and counterproductive work behavior), analysis method (between‐person and within‐person), sleep report source (self‐report, other report, and objective), sleep recall window (day, week/month, and more than 1 month), and study setting (field and laboratory) differentially influence the strength of the sleep–work performance relationship. Furthermore, meta‐analytic SEM results indicate that certain mediators (affect, job attitudes, and cognitive resources) provide stronger explanations (i.e., stronger indirect effects) for the relationship between sleep and work performance, depending on the specific type of performance being examined. In general, results highlight the importance of construct operationalization and methodology decisions when conducting sleep–work performance research and provide greater insight into explanations for the relationship between sleep and work performance. Research implications, practical implications, potential limitations, and future directions are also discussed.     

Empowering leadership: A meta‐analytic examination of incremental contribution,mediation, and moderation

The concept of empowering leadership (EL) has seen increasing scholarly interest in recent years. This study reports a meta‐analysis investigating the effects of EL on employee work behavior. On the basis of data from 105 samples, we found evidence for the positive effects of EL on performance, organizational citizenship behavior, and creativity at both the individual and team levels. We further examined these relationships by exploring potential boundary conditions and the incremental contribution of EL over transformational leadership and leader–member exchange. Furthermore, at the individual level, both trust in leader and psychological empowerment mediated the relationships of EL with task performance, organizational citizenship behavior, and creativity. We also found evidence that leader–member exchange was a significant mediator between EL and task performance. At the team level, empowerment mediated the effects of EL on team performance, whereas knowledge sharing showed no significant indirect effect. Our results have important theoretical and practical implications and suggest some areas that require further research.     

A meta-analytic test of the differential pathways linking ethical leadership to normative conduct

We test how ethical leadership influences normatively (in)appropriate work behavior through distinct mediating pathways, including one's exchange relationship with the leader, ethical culture, and identification with the organization. Our study also controls for transformational leadership as a predictor and trust in leader as a nonhypothesized alternative mechanism. We test our hypotheses using meta-analytic structural equation modeling based on our meta-analysis of 301 independent samples (N = 103,354) and relevant meta-analytic correlations reported in previous research. Supporting our prediction, we found that leader–member exchange, which represents social exchange theory, was the most potent mechanism that accounts for the positive relationship between ethical leadership and task performance. In contrast, ethical culture, which assesses a social learning mechanism, is the strongest predictor of counterproductive behavior. In addition, all three hypothesized mediators each contribute to understanding the positive relationship between ethical leadership and organizational citizenship behavior, although the indirect effect via organizational identification was the weakest. The findings hold after controlling for job satisfaction as another mediator parallel to the theoretical ones. Our results contribute to a precise theory about ethical leadership by differentiating the processes through which it affects employee behavior.     

Understanding organizational embeddedness and career success: Who and what you know

Integrating job embeddedness theory with the sponsored and contest mobility perspectives, we developed and tested a model linking organizational embeddedness with two indicators of career success within the organization (promotion and career satisfaction), via the mediating roles of employees' organizational sponsorship network and job-related human capital development. Data from 188 employees and their supervisors over a 1-year period showed that, after controlling for employees' initial levels of career satisfaction and job performance, only job-related human capital development transmitted the positive effects of organizational embeddedness on promotion and career satisfaction. Supplemental analyses revealed that organizational sponsorship network's positive effects on promotion and career satisfaction were transmitted indirectly, via job-related human capital development. Our findings illustrate the importance of integrating sponsored and contest mobility perspectives and contribute to research on organizational embeddedness by extending its outcomes to include career success within the organization and specifying the process through which organizational embeddedness is related to career success within the organization.     

Psychological ownership and feelings of possession: three field studies predicting employee attitudes and organizational citizenship behavior

An increasing number of scholars and practitioners have emphasized the importance of ‘feelings of ownership’ for the organization (even when employees are not legal owners). In this exploratory study, we examine the relationships of psychological ownership with work attitudes and work behaviors. We start by developing hypotheses based on the psychology of possession and psychological ownership literatures. We then test these hypotheses with data from three field samples, using responses from over 800 employees, as well as manager and peer observations of employee behavior. Results demonstrate positive links between psychological ownership for the organization and employee attitudes (organizational commitment, job satisfaction, organization‐based self‐esteem), and work behavior (performance and organizational citizenship). More important, psychological ownership increased explained variance in organization‐based self‐esteem and organizational citizenship behavior (both peer and supervisor observations of citizenship), over and above the effects of job satisfaction and organizational commitment. Contrary to prior theoretical work on psychological ownership, results, however, fail to show an incremental value of psychological ownership in predicting employee performance.

A model of work frustration–aggression

The current study was designed to investigate the situational, dispositional, and affective antecedents of counterproductive work behaviors. A model based on the organizational frustration–aggression work of Spector and colleagues was tested using structural equation modeling and zero‐order correlational analysis. As expected, a positive relationship was found between employees' experience of situational constraints (events frustrating their achievement of organizational and personal goals) and counterproductive behavioral responses to frustration (personal and organizational aggression), mediated by affective reactions to frustration. In addition, personality (trait anger and trait anxiety), control beliefs (Work Locus of Control), and estimation of likelihood of punishment were strongly associated with affective and behavioral responses. In particular, strong direct relationships were found between affective response variables and anxiety and locus of control, while direct relationships were found between behavioral response variables and anger and punishment. Finally, differentiated relationships between two facets of trait anger (angry temperament and angry reaction) and four categories of counterproductive behaviors (serious and minor deviance directed at organizational and personal targets) were explored.

Justice and job engagement: The role of senior management trust

We examined whether job engagement mediated the effects of organizational justice dimensions on work behaviors and attitudes. Considering distributive and procedural justice from a motivational perspective, we proposed that job engagement would mediate these two dimensions' relations with the work outcomes of task performance, organizational citizenship behavior, and job satisfaction. We also expected this mediation effect would be magnified when senior management trust (SMT) was high. Our results showed that the simple mediation model was supported only for distributive justice. Alternatively, the indirect effect of procedural justice on work outcomes through job engagement was significant only when SMT was high. Implications of our findings and areas for future research are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Daily performance at work: feeling recovered in the morning as a predictor of day‐level job performance

This study examined the state of being recovered in the morning (i.e., feeling physically and mentally refreshed) as a predictor of daily job performance and daily compensatory effort at work. Ninety‐nine employees from public service organizations completed a general survey and two daily surveys on pocket computers over the course of one workweek. Hierarchical linear modeling showed that being recovered in the morning was positively related to daily task performance, personal initiative, and organizational citizenship behavior and negatively related to daily compensatory effort at work. Relationships between the state of being recovered and day‐specific job performance were moderated by job control. For persons with a high level of job control, the relationship between being recovered and daily performance was stronger. Copyright © 2008 John Wiley & Sons, Ltd.     

An Empirical Investigation of the Influence of Safety Climate on Organizational Citizenship Behavior in Taiwan’s Facilities

Although the social exchange relationships between employers and employees are increasingly important to the performance of safety management systems, the psychological effects of work attitudes on this relationship have been less studied. Using a sample of first-line operators and their supervisors from 188 facilities in Taiwan which had Occupational Health and Safety Assessment Series 18000 (OHSAS 18000) certification, the current research conducted an empirical investigation of the influence of safety climate on organizational citizenship behavior (OCB). Work attitude was used to disclose the psychological effect. Research results indicated that (a) safety climate was a significant predicator of OCB, (b) the psychological effect significantly influenced social exchange relationships, and (c) job satisfaction showed a stronger mediating influence than organizational commitment due to the frequent top management turnover. Discussions and implications are also addressed.     

The effects of transformational leadership on teacher attitudes and student performance in Singapore

Transformational leadership theory was examined in 89 schools in Singapore using a split sample technique (N = 846 teachers). The study sought to examine the influence of transformational leader behavior by school principals as it related to organizational commitment, organizational citizenship behavior, teacher satisfaction with leader, and student academic performance. Attitudinal and behavioral data were collected from both teachers and principals; student academic performance was collected from school records. School level analyses showed that transformational leadership had significant add-on effects to transactional leadership in the prediction of organizational commitment, organizational citizenship behavior, and teacher satisfaction. Moreover, transformational leadership was found to have indirect effects on student academic achievement. Finally, it was found that transactional leadership had little add-on effect on transformational leadership in predicting outcomes. Implications and directions for future research are discussed.

Perceived workplace racial discrimination and its correlates: A meta‐analysis

We combine the interactional model of cultural diversity (IMCD) and relative deprivation theory to examine employee outcomes of perceived workplace racial discrimination. Using 79 effect sizes from published and unpublished studies, we meta‐analyze the relationships between perceived racial discrimination and several important employee outcomes that have potential implications for organizational performance. In response to calls to examine the context surrounding discrimination, we test whether the severity of these outcomes depends on changes to employment law that reflect increasing societal concern for equality and on the characteristics of those sampled. Perceived racial discrimination was negatively related to job attitudes, physical health, psychological health, organizational citizenship behavior, and perceived diversity climate and positively related to coping behavior. The effect of perceived racial discrimination on job attitudes was stronger in studies published after the Civil Rights Act of 1991 was passed than before. Results provide some evidence that effect sizes were stronger the more women and minorities were in the samples, indicating that these groups are more likely to perceive discrimination and/or respond more strongly to perceived discrimination. Our findings extend the IMCD and relative deprivation theory to consider how contextual factors including changes to employment law influence employee outcomes of perceived workplace discrimination.

Dynamic effects of personal initiative on engagement and exhaustion: The role of mood,autonomy, and support

Researchers have neglected dynamic effects of proactive behavior on occupational well‐being. We investigated effects of change in personal initiative over 6 months on changes in emotional engagement and exhaustion over the following 6 months. On the basis of the control‐process theory on affect, we hypothesized that changes in positive and negative moods mediate these effects conditional upon employees' level of perceived organizational support. On the basis of action regulation theory, we assumed that change in job autonomy also acts as a mediator. Data came from 297 employees who responded to 3 surveys separated by 6‐month intervals. Results of latent change score modeling showed that change in personal initiative negatively predicted change in positive mood and, when perceived organizational support was low, positively predicted change in negative mood. In addition, change in personal initiative positively predicted change in job autonomy. Change in personal initiative had negative indirect effects on change in emotional engagement, and positive indirect effects on change in emotional exhaustion through changes in positive and negative moods (but not through change in job autonomy). A reverse causal model did not yield significant indirect effects. Overall, these findings suggest that an increase in proactive behavior can have detrimental effects on occupational well‐being.     

Dispositional affectivity as a predictor of work attitudes and job performance

Previous research has shown that dispositional negative affect (NA) is associated with lower levels of job satisfaction. Little research has been conducted, however, on other organizational implications of negative affect or on the potential effects of dispositional positive affect (PA). The present studies examined the relationship of both positive and negative affectivity to organizational commitment, turnover intentions, global job satisfaction and performance. In the first study both NA and PA were associated with organizational commitment and turnover intentions. Additionally, commitment mediated the relationship between dispositional affectivity and turnover. Finally, PA and tenure interacted to predict job performance, such that PA and job performance were positively related, but only for high tenure employees. In Study 2 the findings were generally similar, but not identical. Both NA and PA were related to global job satisfaction and turnover intentions. However, only PA was related to affective organizational commitment. Moreover, both job satisfaction and affective commitment mediated the relationship between dispositional affectivity and turnover intentions. Finally, unlike Study 1, PA was not related to job performance. Rather, NA and tenure interacted such that when individuals were lower in tenure, NA was negatively related to performance.     

Thriving at work: Toward its measurement,construct validation,and theoretical refinement

Thriving is defined as the psychological state in which individuals experience both a sense of vitality and learning. We developed and validated a measure of the construct of thriving at work. Additionally, we theoretically refined the construct by linking it to key outcomes, such as job performance, and by examining its contextual embeddedness. In Study 1, we conducted second‐order confirmatory factor analyses in two samples, demonstrating initial support for the two‐dimensional structure of thriving. We provided evidence for the convergent and discriminant validity of thriving in relation to theoretically related constructs, such as positive and negative affects, learning and performance goal orientations, proactive personality, and core self‐evaluations. In Study 2, across two different samples, we further assessed construct validity by establishing a relationship between thriving and career development initiative, burnout, health, and individual job performance, explaining significant variance beyond traditional attitudinal predictors, such as job satisfaction and organizational commitment. Finally, in Study 3, we focused on understanding the contextual embeddedness of thriving. We found differences in reports of thriving across two points in time, when substantial changes are occurring in peoples' work lives and across contexts (i.e., work and non‐work). Implications for theory and practice, as well as directions for future research, are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Job stress,incivility, and counterproductive work behavior (CWB): the moderating role of negative affectivity

The current study was designed to replicate findings from previous research regarding the relationships between job stressors, negative affectivity, and counterproductive work behavior (CWB) using peer‐reported data and to assess the effects of workplace incivility on employee satisfaction and CWB. Results indicate that incivility, organizational constraints, and interpersonal conflict were negatively related to job satisfaction and positively related to CWB. Support was also found for the role of negative affectivity as a moderator of the relationship between job stressors and CWB, although only one significant moderator was found using peer‐reported CWB. In general, the relationships between job stressors and CWB were stronger for individuals high in negative affectivity than for individuals low in negative affectivity.

Organizational politics and organizational support as predictors of work attitudes,job performance,and organizational citizenship behavior

This study investigated the relationship of organizational politics and organizational support to various work attitudes and behaviors among a field sample of 128 participants. Consistent with our hypothesis, politics and support were related to job satisfaction, commitment, turnover intentions, and supervisor ratings of organizational citizenship behaviors. However, only support was related to job performance. We also examined whether or not organizational politics and organizational support comprise two distinct constructs or one global factor. The evidence here was ambiguous. Fit indices obtained from confirmatory factor analysis suggested that it is more parsimonious to treat politics and support as opposite ends of the same construct, though the two‐factor model did show a slightly better fit. On the other hand, subsequent multiple regression analyses showed that support tended to account for additional criterion variance beyond the effect of politics, implying that there may be some practical utility to retaining politics and support as distinct constructs.

Managers' coping resources,perceived organizational patterns,and responses during organizational recovery from decline

This study proposes that individual coping resources and organizational patterns explain the responses of mid‐level managers to organizational recovery after decline. The study sample consisted of 252 managers in Israeli enterprises recovering from organizational decline. The responses studied were—citizenship responses, negative responses, the wish to exit and acts to exit the organization. Hypotheses were developed relating these responses to individual coping resources of job involvement, self‐esteem and locus of control, and to organizational factors of organic processes, top management support, and organizational opportunities. Findings indicated that most coping resources and organizational patterns correlated with type of response: citizenship behaviors were related to job involvement, internal locus of control, self‐esteem and to perceptions of opportunities and organic processes in the organization. They were negatively related to external locus of control. Negative behavior was negatively related to job involvement, self‐esteem, perceived organizational opportunities and organic processes. The wish to exit related negatively to job involvement, external locus of control, and perceived opportunities. It related positively to self‐esteem. Actual exit behavior was not predicted by the coping resources, nor by organizational factors. Three‐stage multiple regression analyses revealed that individual coping characteristics reduced the impacts of organizational factors for most responses. Implications for management are discussed.

Antecedents and consequences of satisfaction with work–family balance: A moderating role of perceived insider status

This study developed a moderated mediation model to investigate how family‐supportive paid leave and supervision affect employees' satisfaction with work–family balance and in turn their affective organizational commitment and supervisor‐directed organizational citizenship behavior depending on their perceived insider status in the organization. Our analysis of data collected from 118 employee–supervisor dyads in Korean organizations revealed that satisfaction with work–family balance mediated the linkages from family‐supportive supervision to affective organizational commitment and supervisor‐directed organizational citizenship behavior, and the linkage from family‐supportive paid leave to affective organizational commitment. Results further showed that the entire mediational process for family‐supportive supervision was more pronounced for those who perceived themselves to be an insider of their organizations, while the same pattern was not found for the meditational process related to family‐supportive paid leave. Our findings provide theoretical implications for work–family balance research and offer practical suggestions to make employees satisfied with work–family balance.     

The interactive relationship of competitive climate and trait competitiveness with workplace attitudes,stress, and performance

There has been a considerable debate about the individual and organizational benefits of competition. Adopting a person–environment fit perspective, this research examined the influence of competition as an interaction between trait competitiveness and competitive climate. Using a sample of information technology workers, competitive climate was considered as both an individual level variable and a workgroup variable. Results show that the effect of competitive climate depended on trait competitiveness and the level at which climate was assessed for four of the outcomes assessed: job satisfaction, organizational commitment, job dedication, and supervisor‐rated task performance. In general, the effect of competitive climate was more negative for individuals lower in trait competitiveness. Competitive psychological climate was associated with greater stress regardless of the level of trait competitiveness but was not directly related to self‐rated task performance. Findings suggest that managers should be cautious in encouraging competitive climate. Copyright © 2007 John Wiley & Sons, Ltd.
