We explore how relational identification (RI) complements the influence of relational exchange within work role-relationships. In two temporally-lagged studies, we examine the contribution of RI, after accounting for relational exchange quality (REQ), in predicting organizationally-relevant behaviors and attitudes – namely, (1) interpersonal citizenship behaviors (ICBs; person-focused and task-focused), (2) job satisfaction, and (3) affective organizational commitment. Across samples of ‘non-professional’ (N = 152) and ‘professional’ (N = 197) employees, we found that RI (after accounting for REQ) significantly predicted outcomes. Indeed, we found RI to be the only predictor (after accounting for REQ) with affective commitment (‘non-professional’ sample only), person-focused ICBs (both samples), and task-focused ICBs (both samples). We discuss potential approaches for better specifying both identification and exchange as well as their unique and interactive effects within work role-relationships as well as managerial implications, limitations, and future research directions.
