The influence of age and gender composition on group performance and self-reported health disorders was examined with data from 4,538 federal tax employees working in 222 natural work unit groups. As hypothesized, age diversity correlated positively with performance only in groups solving complex decision-making tasks, and this finding was replicated when analyzing performance data collected 1 year later. Age diversity was also positively correlated with health disorders--but only in groups working on routine decision-making tasks. Gender composition also had a significant effect on group performance, such that groups with a high proportion of female employees performed worse and reported more health disorders than did gender-diverse teams. As expected, effects of gender composition were most pronounced in large groups. Effects of age diversity were found when controlling for gender diversity and vice versa. Thus, age and gender diversity seem to play a unique role in performance and well-being. The moderating role of task complexity for both effects of age diversity and the moderating role of group size for both effects of gender diversity further suggest that the impact of these 2 variables depends on different group processes (e.g., knowledge exchange, variation in gender salience).

Daily emotional labor can impair psychological well-being, especially when emotions have to be displayed that are not truly felt. To explain these deleterious effects of emotional labor, scholars have theorized that emotional labor can put high demands on self-control and diminishes limited regulatory resources. On the basis of this notion, we examined 2 moderators of the daily emotional labor process, namely day-specific sleep quality and individual self-control capacity. In particular, in 2 diary studies (NTOTAL = 171), we tested whether sleep quality moderates the influence of emotional dissonance (the perceived discrepancy between felt and required emotions) on daily psychological well-being (ego depletion, need for recovery, and work engagement). In addition, we examined 3-way interactions of self-control capacity, sleep quality, and emotional dissonance on indicators of day-specific psychological well-being (Study 2). Our results indicate that the negative relations of day-specific emotional dissonance to all day-specific indicators of well-being are attenuated as a function of increasing day-specific sleep quality and that self-control capacity moderates this interaction. Specifically, compared with low self-control capacity, the day-specific interaction of emotional dissonance and sleep quality was more pronounced when trait self-control was high. For those with low trait self-control, day-specific sleep quality did not attenuate the negative relations of emotional dissonance to day-specific well-being. Implications for research on emotional labor and for intervention programs are discussed.

In the present study, we examine interactive effects of emotional dissonance (ED) and self-control demands (SCDs; impulse control, resisting distractions, and overcoming inner resistances) on emotional exhaustion, depersonalization, depressive symptoms, and absenteeism. We derived the prediction of interactive effects from the well-founded theoretical argument that both sources of work stress draw on and compete for a common limited regulatory resource. On the basis of 2 German samples (1 cross-sectional and 1 longitudinal sample; NTOTAL = 367), 7 of the 8 interactions tested were found to explain significant proportions of variance in all 4 outcomes considered over and beyond that accounted for by demographic characteristics, outcome stability (longitudinal sample), and main effects. Consistent with our hypotheses, the positive relations of 1 of both stressors (ED or SCDs) to psychological strain and absenteeism were amplified as a function of the other stressor. Theoretical and practical implications of the findings are discussed.

UKCorrelations between absenteeism and work attitudes such as job satisfaction have often been found to be disappointingly weak. As prior work reveals, this might be due to ignoring interactive effects of attitudes with different attitude targets (e.g. job involvement and organizational commitment). Drawing on basic principles in personality research and insights about the situational variability of job satisfaction judgments, we proposed that similar interactions should be present also for attitudes with the same target. More specifically, it was predicted that job involvement affects absenteeism more if job satisfaction is low as this indicates a situation with weak constraints. Both attitudes were assessed in a sample of 436 employees working in a large civil service organization, and two indexes of absence data (frequency and time lost) were drawn from personnel records covering a 12-month period following the survey. Whereas simple correlations were not significant, a moderated regression documented that the hypothesized interaction was significant for both indicators of absence behaviour. As a range of controls (e.g. age, gender, job level) were accounted for, these findings lend strong support to the importance of this new, specific form of attitude interaction. Thus, we encourage researchers not only to consider interactions of attitudes with a different focus (e.g. job vs. organization) but also interactions between job involvement and job satisfaction as this will yield new insights into the complex function of attitudes in influencing absenteeism.'Taking a sickie' is a very common phenomenon in organizations. Recent evidence from the UK, for example, shows that sickness absence accounts for 4% of working time and

Previous research has provided strong evidence for affective commitment as a direct predictor of employees' psychological well-being and as a resource that buffers the adverse effects of self-control demands as a stressor. However, the mechanisms that underlie the beneficial effects of affective commitment have not been examined yet. Drawing on the self-determination theory, we propose day-specific flow experiences as the mechanism that underlies the beneficial effects of affective commitment, because flow experiences as peaks of intrinsic motivation constitute manifestations of autonomous regulation. In a diary study covering 10 working days with N = 90 employees, we examine day-specific flow experiences as a mediator of the beneficial effects of interindividual affective commitment and a buffering moderator of the adverse day-specific effects of self-control demands on indicators of well-being (ego depletion, need for recovery, work engagement, and subjective vitality). Our results provide strong support for our predictions that day-specific flow experiences a) mediate the beneficial effects of affective commitment on employees' day-specific well-being and b) moderate (buffer) the adverse day-specific effects of self-control demands on well-being. That is, on days with high levels of flow experiences, employees were better able to cope with self-control demands whereas self-control demands translated into impaired well-being when employees experienced lower levels of day-specific flow experiences. We then discuss our findings and suggest practical implications. (PsycINFO Database Record
