Prior research indicates that individualism - collectivism orientations (I/C) of employees, as well as organizational justice perceptions - procedural and distributive justice perceptions - influence the following employee attitudes: affective/normative commitments, pro-social behaviour, team loyalty, and tenure intent. Research also suggests that I/C orientations are related to justice perceptions with individualism orientation favouring equity principle and collectivism orientation favouring equality principles. Under the assumption that individualism orientation favours equity and procedural justice principles, we empirically test the main effects of I/C orientations and justice principles on employee attitudes. In addition, we also test whether I/C orientations moderate the relationships between justice perceptions and these employee attitudes. We tested these hypotheses using a survey methodology consisting of a sample of two-hundred and four employees from Ireland. Implications for research and practice are discussed.
