1. Yes I totally would love it and think all Americans should go to a 10-hour, 4-day work week. Two days off is not enough. The Europeans have far more vacation time than us. What's disheartening is that we spend more days at work than not - at least this would even the playing field a little. It feels like your whole life is there then. I would be in favor of someone starting a movement to change this across the U.S.
2. Officially my answer is yes because I value the time off with my family. However, I would argue that a 4-day work weeks can save companies money (i.e. don't have to pay utilities on the 5th day the business is closed) and therefore the cut isn't needed. And I'm still working the same amount of hours, so why cut?
