I like the idea of the 4 day workweek and would absolutely advocate for it, but I'm not sure how I personally would be affected by it. I do rotating 12 hour shift work to operate a power plant. I flip between 36 and 48 scheduled hours, 5 to 5 flipping between days and nights with a few days off between to flip my sleep schedule.

Would my OT start after 32 hours instead of 40? Would my company hire more people to schedule me between 24 and 36 hour weeks as a result? Because I'm not sure they'd be down with paying 4 hours OT on the cheapest weeks of my labor, and 16 hours OT every other week. So they probably have me work less, but does this result in a one time 25% raise and then fall off over time as no further raises come?

Idk, I would be fine either way because of how I budget, but I think these are valid questions that most hourly workers should be concerned about. I don't think it's such a simple concept, and companies will almost certainly find loopholes to exploit to fuck us like they did for the ACA.
