I did it - you can, too (Score 1)

But you have to be very good, and before you try, you have to put in enough time at a company that you become indispensable. Then you will find yourself in a position where you are likely to be able to dictate terms of your work life within reasonable boundaries. I've managed to arrange 4 day/32 hr schedules at two separate companies. Neither company was thrilled about it, and both made it clear that my advancement in the company would cease while I was not working full time. I did this for several years and it was *awesome*. Ever do your grocery shopping on a Monday afternoon? Or go for a hike in a typically mobbed location and find it completely empty on a Thursday morning? It's powerful stuff. If you can afford it, and you're comfortable with putting your career on pause, go for it! But, again, you have to be very good, and you have to be willing to walk over the issue when you bring it up to management. Good luck!
