The proportion of Americans who work long hours has increased substantially over the past 30 years. In the early 1980s, fewer than 9 percent of workers (13 percent of men, 3 percent of women) worked 50 hours per week or more. By 2000, over 14 percent of workers (19 percent of men and 7 percent of women) worked 50 hours per week or more. Overwork began to decline in the mid-2000s, but it remains widespread today. The slowdown in women’s wage gains was especially notable in professional and managerial careers, just the ones where women’s educational advantages should have paid off, but where the stall in pay equality was most evident.
