Seems that I work 5 x 9.5. According to my boss, I should be working 6 x 10 if I want to get anywhere with my career. I get to work by 9, I'm very lucky when I leave by 6:30. Academic life for ya! Many weeks, I have 40 hours in by noon on Thursday. I'd love to walk out at that point, but seems that's not in the cards.
I'd love a 4 x 10 schedule.
