Again, your interpretation of the data is misleading. America makes a lot of people "managers" who are really just senior floor staff. By naming them "managers" those employees very often move to salaried (instead of hourly wage) earners. Salaried employees do not get paid for overtime; in fact, a large percentage of salaried workers regularly scheduled work days are 45 to 55 hours per week. Check upper executive numbers. There remains a real dearth of women in upper executive positions.

To those salaried hours, as an example… My husband used to be the manager of a small business restaurant. His weekly schedule was 50 hours a week. That was bad enough. But, when he went to a corporate fast food chain as a store manager, his hours were minimum 55 per week; and he and his assitant manager (the only other salaried employee in the store) were required to "make up the labor" to cover shifts. Plus, every time his store met labor costs, corporate cut labor. Then, corporate eliminated the assistant manager position. My husband ended up working 60 to 70 hours a week. When we calculated his salary out by the hours he'd worked that last year, he averaged $6.20 per hour – in a country where the federally mandated minimum hourly wage is $7.25 per hour.
