Partners' overwork and individuals' wellbeing and experienced relationship quality.

The negative impact of long work hours, or overwork, on individuals' physical and psychological wellbeing is well documented. Less is known about the impact of overwork on individuals' families, especially in regard to partners. In this paper, we address this gap in the literature using high quality data from the Work, Family, and Health Network in a sample of IT workers in the US (N=590). Specifically we examine whether partners' long work hours are associated with individuals' perceived stress, time adequacy with partner, and relationship quality, and whether these relationships vary by gender. In addition, following the marital stress model, we investigate whether any negative correlation between partners' long work hours and relationship quality is mediated by time adequacy or perceived stress. We find that women partnered to men who work long hours (50 or more hours per week) have significantly higher perceived stress and significantly lower time adequacy and relationship quality compared to women partnered to men who work a standard full-time work week (35-49 hours). Further, the increased stress associated with being partnered to a man who overworks, not lower time adequacy, mediates the negative relationship between overwork and relationship quality. Conversely, we find that men partnered to women who work long hours report no differences in stress, time adequacy, or relationship quality than men who are partnered to women who work a standard full-time work week. Our results highlight the need for more research that examines the impact of overwork on individuals and their families.
