I would happily work 4 10 hour days to get a third day off.
I did that once and it killed me. I could never keep that up on a regular basis.
I’ve been doing it for about two years now and I think it’s pretty incredible. Consistently having a third day off can do wonders; commute only 4 times a week, your third day off is a weekday so basically always have a great day to go shopping, appointments, etc while everyone else is at work. I don’t think I could ever go back to 5 8’s. The only thing better would be 4 8’s
