We've officially had the 40-hour week since the early part of the 20th century thanks to courageous and determined efforts of the labor movement during that era.
Advances in productivity haven't led to a substantial increase in wages nor reduction in hours worked for the average employee. An increase in wages in proportion with productivity should help boost an argument for reducing the work week from the now standard 5-day week/8-hour day to 4-day week/9-hour day. Or we could just make Fridays a half-day. Or turn Thursdays and Fridays into 6-hour days with an adjusted wage increase.
