In the present study, the effect of partners’ social support on women’s reentry into the labor market is examined by means of discrete-time event history analysis using the German Socio-Economic Panel (1984-2013). In doing so, we take into account partners’ instrumental and emotional support. A special focus is placed on the moderating effect of partners’ relative resources on partners’ support. Results reveal that both partners’ instrumental and partners’ emotional support play a major role in women’s return to employment. Particularly with a more egalitarian division of domestic labor and child care, women have a higher likelihood of returning to the labor market. However, a partner’s reduction of working hours can also accelerate women’s reemployment. In addition, we find moderating effects of partners’ resource constellations on partners’ support: with a partner’s increasing comparative advantage, help with housework facilitates labor market reentry, while educational homogamy moderates the effect of a partner’s emotional support.
