I think I'd rather work 5 days a week and get 2 off. This way I can at least get home to spend some time with my kids. If I had to work later on days then I wouldn't have as much time with my kids and the one extra week day I would get off wouldn't help much because one of my kids would still be in school most of that day.
Every chance I get I work four 10 hour days. That way I still get home at a decent time and have an extra day off. The extra 2 hours are not near as bad as having to get up and go to work a whole day. Too bad they don't let me do this every week.
