Bottom-Line pursuits invade your family: the spillover effect of supervisor bottom-line mentality on employee work-to-family conflict

Purpose
The purpose of this study is to investigate the relationship between supervisor bottom-line mentality (BLM) and employee work-to-family conflict (WFC) through employee psychological detachment, and the moderating role of employee trait optimism.

Design/methodology/approach
The research model was empirically tested using a sample of 225 two-wave data gathered from five Chinese companies.

Findings
The results revealed that employee psychological detachment mediated the impact of supervisor BLM on employee WFC. Moreover, employee trait optimism buffered the negative relationship between supervisor BLM and employee psychological detachment and the indirect effect of supervisor BLM on employee WFC through employee psychological detachment.

Practical implications
Supervisors should pay more attention to the spillover effect of supervisor BLM on employees’ family life and take some training measures to help employees effectively psychological detach from supervisor BLM.

Originality/value
The findings, therefore, provide a more comprehensive understanding of the adverse effects of supervisor BLM beyond the work domain and the buffering role of employee trait optimism on work–family intervention.
