Actually, for over eight years I have been employed using a 4 day 10 hour day week, soon I will be moving to a 3 day 12 hour day week, to balance with my education pursuits. I have done this before, so it is not completely new, it works out well for me even factoring in a 45 minute commute, one way. Though, I am with out children, which would most likely not be achievable with this type of schedule or at least as easily.
