not that much happier, no, but it's non-zero. esp with commute time, arranging lunch outside the home, parking or public transportation costs, childcare costs and all sorts of other little expenses that just vanish when you can stay home. Plus a 4x10 schedule doesn't result in a pay cut the way going from 5x8 to 4x8 would. My mom worked 4x10 as a nurse my entire childhood and loved the extra day.
