Some healthcare professionals do that. 4x10h or some similar flavor. But again the same problem hold if you have children. Assuming a very short 30m commute and lunch on the go, you are still gone 11h a day. More realistically, that's 12h/day. Smaller children that wake up at 7 will be in bed around 7:30, so the only time you're with them is during feeding/bath and that's it. You can make up for it the remainder 3 days of the week, but if your 4 work days are contiguous, that's a long time to be essentially absent as a parent.
