In 2007, 20 percent of employed persons did some or all of their work at home on days that they worked, and 87 percent did some or all of their work at their workplace, the U.S. Bureau of Labor Statistics reports in its American Time Use Survey.

The survey focuses on the average amount of time per day in 2007 that Americans worked, did household activities, cared for family, participated in educational activities, and engaged in leisure activities. It finds that although employees worked an average of 7.6 hours on the days that they work, they worked longer during a weekday (7.9 hours) than on a weekend day (5.6 hours). Multiple jobholders (62 percent) were almost twice as likely to work on an average weekend day as were single jobholders (33 percent). Employed men worked at their jobs about three quarters of an hour more than employed women, but women spent more time on household activities than men, according to the survey.
