Drawing on social identity theory and organizational justice research, we model the impact of employee perceptions of human resource (HR) policies and practices on two important outcome variables - discretionary work effort (DWE) and co-worker assistance (CWA). Results based on 618 full-time employees in two organizations show that HR practices are positively related to procedural and distributive justice and that organizational identification mediates the relationship between procedural and distributive justice and DWE and CWA, respectively. Distributive justice is also shown to have direct effects on the two outcome variables suggesting the relevance of a social exchange perspective as a complement to social identity explanations. Implications for research and practice are briefly discussed.
