Drawing upon role identity theory and the dual judgment model of perspective-taking, we investigated a model describing the relationship between supervisor family identity salience (SFIS) and supervisor work-family support, with supervisor work identity salience (SWIS) as a moderator and supervisor work-family perspective taking as a mediator. We tested the model using two data sets. Results from supervisor-reported data indicated that SFIS was related to supervisor work-family perspective-taking, which was, in turn, related to supervisor work-family support. Results from leader-follower dyadic data found that SFIS was related to work-family support. In both samples, the effects of SFIS were stronger when SWIS was high. We discuss the theoretical and practical implications of these findings.
