In the mid-20th century, union leader Harry Van Arsdale Jr became obsessed with a simple idea: fewer working hours would mean a need for more workers, and therefore more jobs. He considered it the solution to unemployment, and his union fought to realize it.
This is actually my complaints with unions from the 70’s to the 2k’s. It felt like it became less about shortening the workweek and expanding the base than with bookoo overtime.
