Support at Work, Capitalization at Home: The Interpersonal Effects of Family‐Supportive Supervisor Behaviors
研究家庭支持型主管行为如何通过工作家庭人际资本化提升主管的家庭角色表现，进而改善伴侣的家庭体验，并发现家庭和谐低时这种效应更强。
ABSTRACT Family‐supportive supervisor behaviors (FSSBs) have been widely recognized for helping employees navigate work–family demands. Yet, it remains unclear whether the benefits of FSSB extend beyond the workplace to enrich supervisors themselves and their partners at home. Drawing on work–family enrichment theory and family systems theory, we propose a spillover–crossover framework to examine how engaging in FSSB enhances supervisors' family role performance and, in turn, positively associates with their partners' family experiences. Using a weekly experience sampling method with data from dual‐earner couples, we find that FSSB is positively related to supervisors' family role performance via work–family interpersonal capitalization. This enhanced family role performance subsequently crosses over to improve partners' family role performance. Contrary to expectations, the relationship between FSSB and interpersonal capitalization is stronger when family harmony is low, suggesting a compensatory effect. By shifting the lens beyond employees, our study highlights the broader relational reach of FSSB and offers new insights into its cascading impact across work and family domains.
