In 1965, the average workweek for production and nonsupervisory workers was 38.6 hours, close to the mythical 40-hour workweek. It’s declined ever since, we are wealthier. In 1975 it was 36 hours, in 1985 it fell to 34.9, in 1995 34.3, and by 2005 33.8 hours/week! It has since leveled off and in 2022 was 34 hours/week. We are moving to a 32-hour workweek probably composed of four 8-hour days.
