Various studies have demonstrated that work-to-family enrichment (WFE) benefits employees in both the work and home domains. However, these findings may overstate the benefits of WFE and ignore its potential dark side. We advance the research on WFE by integrating conflict theory into the concept of WFE to investigate whether and how employee–spouse perceptual congruence in employee WFE influences employee family cohesion and emotional exhaustion. The results of polynomial regressions on 225 employee and spouse dyads revealed that the perceptual congruence in employee WFE between employees and spouses was negatively associated with relationship conflict. Additionally, asymmetrical incongruence effects were found, wherein spouses perceived a higher relationship conflict with employees when their perceptions of employee WFE were lower than those of the employees. Furthermore, spouses' perceived relationship conflict with employees mediated the influences of employee–spouse perceptual congruence in employee WFE on employee family cohesion and emotional exhaustion.
