This article investigates how mothers’ and fathers’ daily time use changed across social classes from 1990 to 2013 in Germany. In the 2000s, Germany’s adherence to the male breadwinner model was eroded by labor and family policy reforms typical of the adult worker model, which assumes individual self-sufficiency. The implications for gender and class inequality have been heatedly discussed. Drawing on the German Time Use Survey, I find that gender equality in the division of labor is greatest among full-time dual-earner couples with standard schedules. The prevalence of this pattern increased among the middle- and upper-class in historically conservative western Germany, but declined across classes in formerly socialist eastern Germany. In parallel, nonstandard work patterns and dual-joblessness gained in importance among lower-class couples, particularly in eastern Germany. I conclude that the adult worker model benefited mothers with access to standard full-time jobs but at the cost of greater class polarization.
