I did the sub-40 hour thing for a while at an old job. I was starting to go to grad school full time, so I asked my company if I could could move from being on salary to being an hourly employee and work about 20+ hours a week. Because it was better for them to keep me on in a limited capacity rather than spend the money hiring and training someone new they were really cooperative. The extra time flexibility was great, I got to keep my insurance with them, and got out of grad school debt free! If you can find yourself a good non-standard situation that works well for you (and your future) take it!
