We here in America, have some of the longest work weeks, and are the least vacationed people around. I would love to go to a 4 day work week, and work 4 ten hour days instead of working 5 eight hour days. That would give you a 3 day weekend, and make the weekends that much longer. Which would be nice if you were trying to have some more time to relax. The problem is, that everyone here expects you to be on call 24/7 which in itself is just super stressful. So I think people would be in a lot better moods if we had one more day of free time.
