A multilevel study of the relationship between organizational justice and affective commitment : The moderating role of organizational size and tenure

Purpose – The purpose of this paper is to examine the moderating role of organizational size and individual tenure on the relationship between organizational justice and organizational affective commitment. Based on the literature on organizational justice and justice climate, this paper tests whether the role of justice climate, measured at the organizational level, is affected by these organizational and individual characteristics in determining individual organizational affective commitment. Design/methodology/approach – Data on 20,936 employees from 1,496 companies that were included in the 2004 Workplace Employment Relationships Survey were used. Findings – Hierarchical linear modeling analysis shows that the importance of the justice climate extends beyond its effect on individual perceptions. Moreover, whereas the organization size does not influence the justice climate – affective commitment relationship, organizational tenure moderates it. Originality/value – This study shows the impact of justice climate on affective commitment beyond the effect of individual justice. It also examines organizational (organization size) and individual characteristics (tenure) as possible moderators, constructs rarely considered in studies on justice climate.
