ABSTRACT Part-time work is an increasingly common strategy for handling work and family – but is it an effective strategy everywhere and for everyone? To answer this question, we examine satisfaction with work–life balance (SWLB) of workers in 22 European countries. Our results show that part-time workers have higher SWLB than full-time workers; the more so, the fewer hours they put in. Yet, we find an important gender difference: women in marginal part-time work are more satisfied than men in a similar situation, and conversely men in full-time work have higher SWLB than women working full-time. Further, the societal context plays an important role: substantial part-time work is more conducive to SWLB in more gender-egalitarian countries than in countries with low gender equality. Hence, a supportive gender climate and institutional support may entice workers to reduce working hours moderately, which results in markedly increased levels of SWLB.
