In 1997, workers with extended workweeks had a wide range of earnings premiums. More than half earned at least 32 percent more per week and about 67 percent earned more per hour than did those who worked a standard week.
In nearly 90 percent of managerial, management-related, and sales occupations, weekly earnings of workers with an extended workweek exceeded those of workers with a standard workweek by at least 32 percent. For sales workers, the opportunity to earn more commissions with additional hours bumps up the pay premiums, especially among women.
In contrast, among professional specialty workers and technicians, two-thirds had premiums below 32 percent, and actually earned less per hour. This may be due, in part, to professional workers being paid annual salaries unrelated to the number of hours worked.
A standard workweek is defined as one in which usual hours worked fall between 35 and 44 hours. Extended workweeks are those in which usual hours worked fall between 45 and 99 hours.
