Family supportive supervisor behaviors (FSSB) have emerged as a powerful resource
of informal support for the well‐being and development of employees. However,
research to date offers limited insight into the antecedents and underlying processes
that may trigger FSSBs. We investigate the association between family motivation of
supervisors and FSSBs, and how the latter mediates the association between
supervisors’ family motivation and subordinates’ work performance. Furthermore,
we examine the role of supervisors’ satisfaction with their work–family balance as a
contextual variable influencing our proposed associations. We draw on FSSB and
perspective taking theory as over‐arching frameworks for our hypotheses. Using
matched and multisource supervisor‐subordinate data collected from an organization in Chile (196 subordinates and 75 supervisors), our findings revealed that FSSBs
are mechanisms linking supervisors’ family motivation to subordinates’ work
performance. Interestingly, this positive association is moderated by supervisors’
satisfaction with their work–family balance, such that the mediation of FSSBs is
stronger for supervisors who are not satisfied with their work–family balance
