Article International Review of Administrative Sciences Not all justices are equal: the unique effects of organizational justice on the behaviour and attitude of government workers in Ghana Anthony Sumnaya Kumasey University of Professional Studies, Ghana Eric Delle Macquarie University, Australia Farhad Hossain University of Manchester, UK Abstract Drawing on social exchange and positive emotions theories, we examined the differ- ential effects of organizational justice on work engagement and organizational commit- ment among 347 Ghanaian public-sector workers. We hypothesized that three different components of organizational justice (distributive, procedural and interactional) would have different effects on work engagement and organizational commitment. We used regression test to investigate these effects. Despite subtle differences, the results show that distributive and procedural justice relate positively to vigour, dedication and absorption. However, interactional justice was unrelated to any of the work engage- ment components. We further observed that while distributive, procedural and interactional justice related positively to affective commitment, no other type of orga- nizational justice related to continuance and normative commitment. Overall, not all justices create the same effect on workplace behaviour. Implications and limitations are discussed.
