A
recent study at Cornell University found that for female professionals, having a husband working 60 hours a week or more made them 51 percent more likely to quit their jobs. "The findings suggest that the prevalence of overwork may lead many dual-earner couples to return to a separate spheres arrangement: breadwinning men and homemaking women," says Youngjoo Cha, the sociology researcher who wrote the study. Putting in extra hours yourself won't affect him at all, but don't resign yet: Full-time working women who are married make more on average than their single counterparts.
