Perceived Organisational Support as a Moderator in the Relationship Between Organisational Justice and Affective Organisational Commitment

Abstract Purpose. This study aimed to explore the relationship between organisational justice and commitment and how the combined influence of organisational justice and perceived organisational support (POS) impacts on commitment. Research Methodology. Data were obtained through questionnaires administered to 124 teaching and non-teaching staff, who were conveniently selected by the researchers from Ghanaian public universities. Descriptive survey design was adopted for this study. Findings. The results from regression analysis of data collected showed a significant positive relationship among the dimensions of organisational justice and affective commitment. Furthermore, POS was found to moderate the relationship between organisational justice and commitment, as the effect of justice on commitment increased when POS was added to the model. Practical Implications. The present study supported the expected relationship among justice, POS and organisational commitment and implied that higher level of fairness and support from the organisation can favourably influence the commitment level of employees. Originality. The current research examines the moderating role of POS on organisational justice–commitment link using samples from the Ghanaian higher education institutions. Thus, it makes relevant contribution to the existing literature by modelling both organisational justice and support and analysing its effect on organisational commitment.
