This study investigated the relationship between family-work conflict (FWC) and work-from-home productivity (WFHP) among Taiwanese employees during the COVID-19 pandemic. A quantitative approach using a questionnaire (1177 respondents, 785 valid cases) examined the mediating roles of work engagement (WE) and self-efficacy (SE), and the moderating role of work-from-home days (WFHDs). Results showed FWC negatively affected WE, SE, and WFHP. The negative impact of FWC on WFHP was stronger for employees with more WFHDs. WE and SE partially mediated the FWC-WFHP relationship. Gender differences in WFHP were also observed. The study offers managerial implications for employers and governments regarding family-friendly policies, employee training, and work hour regulations.
