The literature concerning the relationship between emotional exhaustion and performance led researchers to raise questions about the extent to which the variables are related. In 2 time-lagged samples, the authors found that motivation mediates the emotional exhaustion-job performance relationship. Moreover, the authors found that participants appear to target their investment of resources in response to emotional exhaustion to develop social support through social exchange; specifically, emotional exhaustion was associated with communion striving resources that were manifest in the form of organizational citizenship behaviors targeted at individuals. Implications of this relationship for theories of burnout and for management practice are discussed.

This study examines the role of social network ties in the performance and receipt of interpersonal citizenship behavior (ICB), one form of organizational citizenship behavior (OCB). A field study involving 141 employees of a manufacturing firm provided evidence that social network ties are related to the performance and receipt of ICB. Results support hypothesized relationships, which are based on social exchange theory, suggesting strength of friendship is related to performance and receipt of ICB. Support was also found for impression management-based hypotheses suggesting that asymmetric influence and 3rd-party influence are related to the performance and receipt of ICB. These relationships were significant when controlling for job satisfaction, commitment, procedural justice, hierarchical level, demographic similarity, and job similarity. Implications and directions for future research are addressed.

This study draws from social information processing theory and the climate literature to examine an antecedent to and the consequences of voice climate, defined as shared group member perceptions of the extent to which they are encouraged to engage in voice behaviors. The authors test their hypotheses using data collected from a sample of 374 full-time employees nested in 54 work groups. Their results indicate that group perceptions of supervisor undermining have a negative effect on group perceptions of voice climate. In addition, voice climate predicts group voice behavior and also has a significant influence on group performance beyond the influence through group voice behavior. These findings provide additional evidence for the predictive validity of the voice climate construct and provide future research opportunities for researchers.

Although prior studies have indicated that organizational citizenship behaviors (OCBs) tend to be positively related to supervisory ratings of employee performance, only a few studies have investigated how the motives attributed to OCB (e.g., impression management, prosocial motives, organizational concern) might influence such evaluations. Based on Weiner's (1995) attribution model and a study of supervisors in varied industries, we found that attributions regarding employees' motives for engaging in OCB are related to supervisors' emotional reactions to such behavior, which are, in turn, related to ratings of employee performance. Implications of the study for management research and practice are discussed.j asp_625 1450..1489 model to explain how supervisors interpret citizenship behavior based on the attributions they make about the motives underlying the behavior and how these attributions, in turn, influence their behavioral reactions to the OCBs. We conclude by discussing the theoretical and practical implications of supervisor attributions for OCB and by suggesting directions for future research.

In a field study of 114 participants, the authors tested components of leader—member exchange (LMX) theory within the context of informal organizational networks, finding support for instrumental components within quality LMX relationships. Similarity to leader competence and personality was relevant to follower-rated LMX. In addition, leader centrality moderated the relationship between interaction frequency and follower-rated LMX. Leader-rated LMX quality was related to personality and competence similarity to followers, but only when followers' advice centrality was high. Outside workgroup centrality positively moderated relationships between inside workgroup centrality and LMX quality. Overall, the instrumental value to LMX quality was emphasized more for leaders than for followers.
