Many researchers have concerns about work engagement's distinction from other constructs and its theoretical merit. The goals of this study were to identify an agreed‐upon definition of engagement, to investigate its uniqueness, and to clarify its nomological network of constructs. Using a conceptual framework based on Macey and Schneider (2008; Industrial and Organizational Psychology, 1, 3–30), we found that engagement exhibits discriminant validity from, and criterion related validity over, job attitudes. We also found that engagement is related to several key antecedents and consequences. Finally, we used meta‐analytic path modeling to test the role of engagement as a mediator of the relation between distal antecedents and job performance, finding support for our conceptual framework. In sum, our results suggest that work engagement is a useful construct that deserves further attention.

Recent conceptual and methodological advances in behavioral safety research afford an opportunity to integrate past and recent research findings. Building on theoretical models of worker performance and work climate, this study quantitatively integrates the safety literature by meta-analytically examining person- and situation-based antecedents of safety performance behaviors and safety outcomes (i.e., accidents and injuries). As anticipated, safety knowledge and safety motivation were most strongly related to safety performance behaviors, closely followed by psychological safety climate and group safety climate. With regard to accidents and injuries, however, group safety climate had the strongest association. In addition, tests of a meta-analytic path model provided support for the theoretical model that guided this overall investigation. The implications of these findings for advancing the study and management of workplace safety are discussed.

The causes of workplace deviance are of increasing interest to organizations. We integrate psychological and neurocognitive perspectives to examine the effects of sleep deprivation on workplace deviance. Utilizing self-regulatory resource theories, we argue that sleep deprivation decreases individuals' self-control while increasing hostility, resulting in increased workplace deviance. We test our hypotheses using two samples: one comprised of nurses from a large medical center and another comprised of undergraduate students participating in a lab study. Results from both samples largely converge in supporting our hypotheses.

We examine the daily sleep of leaders as an antecedent to daily abusive supervisory behavior and work unit engagement. Drawing from ego depletion theory, our theoretical extension includes a serial mediation model of nightly sleep quantity and quality as predictors of abusive supervision. We argue that poor nightly sleep influences leaders to enact daily abusive behaviors via ego depletion, and these abusive behaviors ultimately result in decreased daily subordinate unit work engagement. We test this model through an experience sampling study spread over 10 workdays with data from both supervisors and their subordinates. Our study supports the role of the indirect effects of sleep quality (but not of sleep quantity) via leader ego depletion and daily abusive supervisor behavior on daily subordinate unit work engagement.
