ABSTRACT Role strain theory illuminates how work and family impinge on our intimate lives in gendered ways. Drawing upon data from the 2012 European Social Survey, we estimate structural equation models to understand the links between work and family conditions on full-time dual-earning couples’ restless sleep and emotional wellbeing. Our results show that young children (aged two or under) disrupt full-time working mothers’ but not full-time working fathers’ sleep, improving emotional wellbeing for fathers but not mothers. Compared to men, women report a significantly larger association between work hour dissatisfaction and restless sleep, probably highlighting the more time strain they experience due to their family responsibility on top of their full-time work. These gender gaps are the most pronounced among those couples working longest hours, suggesting that when inter-role strain intensifies for both partners, women suffer disproportionately. Collectively, our findings identify significant and gendered consequences of childcare and workplace demands and spotlight restless sleep as a key mechanism linking women's role strain to poor emotional wellbeing.
