Gender inequities can be partly traced back to gender differences in working time arrangements. In fact, it is established knowledge that women as compared to men are more (less) likely to work part-time (overtime). Based on social role theory, however, we also expect gender differences among part-time and overtime workers, such that women and men differ in why they work part-time or overtime. In a preregistered and highly powered study conducted in Germany (N = 3,844-17,361, depending on the analysis), we observed that, on average, women were more likely than men to work part-time (i.e., fewer than 35 hours per week) because of personal or family obligations. Moreover, in comparison to men, women were less likely to work overtime (i.e., at least two hours per week) to attain additional income, but more likely to work overtime to step in for colleagues. Altogether, people had "gendered" reasons to work certain hours. Furthermore, as people's paid working time arrangements are intertwined with their lives outside of the workplace, we examined women’s and men’s work-life interface and observed that women (as compared to men) deemed it less acceptable to be available for work-related issues during leisure time. We discuss implications for future theorizing and for practitioners who aim to design work schedules that consider the different lived experiences of women and men.
