In this article, the authors used a within‐person design to examine the relationship between job insecurity and employee in‐role and extra‐role performance, and the buffering role of time‐varying work‐based support (i.e., supervisor and colleague support) in this relationship. Weekly diary data gathered over the course of three weeks from 56 employees confronted with organizational restructuring and analyzed with a hierarchical linear modeling approach showed that weekly fluctuations in job insecurity negatively predicted week‐level in‐role performance. As predicted, supervisor support moderated the intra‐individual relationship between job insecurity and in‐role performance, so that employees' in‐role performance suffered less from feeling job insecurity during weeks in which they received more support from their supervisor. No relationship between job insecurity and extra‐role performance was observed. This within‐person study contributes to research on job insecurity that has primarily focused on inter‐individual differences in job insecurity and their associations with job performance. Theoretical and practical implications for human resource management are discussed. © 2012 Wiley Periodicals, Inc.

Building on self-determination theory, we examined the relationship between shared work values and work engagement within teams. Specifically, we expected that employees would show higher levels of work engagement when working in teams characterized by intrinsic relative to extrinsic work values, and that this relationship can be explained by basic psychological need satisfaction. Multilevel analyses using data from 307 employees taken from 31 teams working in a variety of sectors in Belgium and the Netherlands largely supported the hypotheses: Individual-level need satisfaction partially mediated the relationship between team-level work values and individual-level engagement. Implications for practice and theory are discussed.

Based on the perspective of the psychological contract, this study among 2,782 constabulary officers tested the hypothesis that threats of workplace violence lead to reduced job investments (i.e., affective organizational commitment and dedication). Multilevel analyses showed negative relationships between threats of workplace violence (individually experienced and as expressed in an unsafe climate) and job investments. Peer support was related to more job investments and buffered an unsafe climate, that is, the negative relationship between an unsafe climate and reduced job investments was stronger for employees with low levels of peer support. Experiencing an unsafe climate at the aggregate level by the cumulative experience of threat by employees can perhaps be thought of as facing a common enemy, and it has been shown that this has consequences for employees' attitudes that can be buffered by peer support.
