I currently work 30 hours per week and love it! I started out here at 20 hours and then went to 30. If they needed me to go to 40 hours I would really have a hard time doing so. I've been accustom to my Friday's off for so long. I always said that once my DS went to Kindergarten I would work shorter days/5 days a week, but I don't think that will be happening. I enjoy my day off to much!
