As a machinist I hated the 4x10s.. it's great for a while, you think you get a long weekend, but for me, I was up at 3am to get to work and start at 5am with my commute, then finished at 330pm, got home around 6 sometimes depending on traffic, and had to be in bed so early (like 730) to get enough sleep I had no social life on week nights OR I had less than 5 hours sleep a night, and in either case I didn't have enough time to even keep a clean house during the week (single man home owner with no kids or anyone to pick up slack). So where I thought it'd be great having a long weekend, Friday was always spent asleep, too exhausted to do anything, and having to do all my chores and errands that were neglected during the week, and I had to be in bed so early Sunday, it felt like I only got half a weekend.. it sucked in summer.. even with blackout curtains. I'd end up sleeping on the couch in a nest and not showering or changing my work clothes for days to save time.

As an office jerk or working from home though it may be different. That was my experience. I'd go all week without seeing the sun till the weekend in winter lol.
