Findings from a field survey of 192 supervisor-subordinate dyads revealed that status resource was positively related to OCB and career growth opportunities. MMX moderated the relationship between OCB and status resource in such a way that the relationship was stronger in the low MMX context than in the high MMX context. The main contribution of this study is an explanation of the effects of OCB on individual careers from a fine-grained perspective based on resource and relational theories.展开更多
