Past research has not clearly explained why the quality of leader-member exchange (LMX) is weakly related to organizational citizenship behaviour (OCB) in non-Western cultures. Hence, this study explores subordinates’ cultural value orientation and team member exchange (TMX) as boundary conditions of the effects of LMX on citizenship behaviour directed at individual organizational members (OCBI) and citizenship behaviour directed at the organization as a whole (OCBO). The research hypotheses were tested using a sample of 392 supervisor-subordinate dyads from organizations across different sectors in Ghana. The results support our theorizing that horizontal collectivism and TMX strengthen the relationship between LMX and OCBI such that the relationship is stronger for horizontal collectivists and under a high TMX context. However, the results did not support the hypothesized moderator effects of horizontal collectivism and TMX on the LMX-OCBO relationship. The theoretical contributions, managerial implications and avenues for further research are discussed.
