A well-known phenomenon in many societies is that, on average, women (as compared to men) work fewer paid hours but also engage in more caregiving. That is, women are more likely to work part-time, whereas men are more likely to work overtime. Yet, of course, there are also many women working overtime, just like there are many men who work part-time. In this research, we asked: Do women and men differ as to why they work part-time or overtime? And yes, they did! We observed that women who worked part-time (as compared to men working part-time) were more likely to do so for personal or family reasons. Moreover, women who worked overtime (as compared to men working overtime) were more likely to do so in order to step in for colleagues as well as less likely to do so to attain additional income. Altogether, women and men had slightly different reasons for working a certain number of hours. This knowledge might be helpful for organizations that aim to provide working conditions that serve the potentially varying interests of their employees.
