Researchers have recently drawn attention to performance elements that extend beyond task performance (often labeled as organizational citizenship behavior, or OCB). A second stream of research concerns detrimental, potentially destructive acts that hurt colleagues or organizations (labeled counterproductive work behavior, or CWB). Spector and Fox (in press) have proposed a model based upon conceptual parallels that may help connect these two disparate fields of research, using positive and negative emotions as intermediary variables between environmental conditions and extra-role work behaviors. The current study tested portions of the overall model, and found reasonable support for the components. Suggestions for further research designed to test the overall model are presented.
