The authors examined the direct and indirect effects of organizational policies and practices that are supportive of family responsibilities on work-family conflict and psychological, physical, and behavioral measures of strain. Survey data were gathered at 45 acute-care facilities from 398 health professionals who had children aged 16 years or younger at home. Supportive practices, especially flexible scheduling and supportive supervisors, had direct positive effects on employee perceptions of control over work and family matters. Control perceptions, in turn, were associated with lower levels of workfamily conflict, job dissatisfaction, depression, somatic complaints, and blood cholesterol. These results suggest that organizations can take steps that can increase employees' control over family responsibilities and that this control might help employees better manage conflicting demands of work and family life.

It has been hypothesized that the positive relation between stress and strain responses is stronger for individuals who have low levels of social support than for those who have high levels of support. This hypothesis that social support buffers (moderates) the negative effects of stress has been tested extensively in a variety of setting with highly conflicting results. Some theorists have recently proposed that the moderating effect of social support is itself buffered by other variables such as sex or social class. The present study was designed to examine the role of social support in the experience of work stress with a sample large enough to provide statistically powerful tests of models of social support that specify two-way and three-way interactions. No support for higher order interactive models was found. In addition, no evidence emerged demonstrating any buffering effect for social support. Arguments are advanced for a parsimonious model in which social support has a modest direct effect of lowering experienced strain.

Research examining the relationship between work stress and well-being has flourished over the past 20 years. At the same time, research on physiological stress processes has also advanced significantly. One of the major advances in this literature has been the emergence of the Allostatic Load model as a central organizing theory for understanding the physiology of stress. In this article, the Allostatic Load model is used as an organizing framework for reviewing the vast literature that has considered health outcomes that are associated with exposure to psychosocial stressors at work. This review spans multiple disciplines and includes a critical discussion of management and applied psychology research, epidemiological studies, and recent developments in biology, neuroendocrinology, and physiology that provide insight into how workplace experiences affect well-being. The authors critically review the literature within an Allostatic Load framework, with a focus on primary (e.g., stress hormones, anxiety and tension) and secondary (e.g., resting blood pressure, cholesterol, body mass index) mediators, as well as tertiary disease end points (e.g., cardiovascular disease, depression, mortality). Recommendations are provided for how future research can offer deeper insight into primary Allostatic Load processes that explain the effects of workplace experiences on mental and physical well-being.

We examined the impact of stressful job demands on employee attitudes and attendance. Using Karasek's (1979) theory of job decision latitude as the conceptual foundation, we hypothesized that mental and physical work demands would interact with employee beliefs of personal control. Survey data from 90 male manufacturing employees regarding their control beliefs were combined with objective job analysis data concerning mental and physical demands and one year's worth of archival data regarding unexcused absences, sick days, and days tardy. There were significant interactions between control and objective psychological demands that indicated that these demands were associated with higher levels of tardiness and sick days only under conditions of low perceived control. In contrast, subjective workload ratings showed no relationship with tardiness and sick days, but, in interaction with control, predicted work satisfaction and voluntary absence. We discussed these results in terms of a stress process that affects health-related attendance independent of employee attitudes.
