As always when this comes up, I ask about schools. Every single school system that has tried 4 day school weeks has had poor outcomes across the board. Children do worst academically and they fair worst socially, since that one less day is one less day that at risk children have access to either safety or food in some cases.

We can't ask teachers to work 5 days when the rest of the world doesn't. I'd also be interested in how much of the value some people are pulling from 4 day work weeks is just having a kid-free day to accomplish things. Would the value for care takers (who would make up a significant amount of young people) the same if their children accompanied them?

I don't really have an opinion on the 4 day work week, but I do think it's important to consider impact from all angles. I just never see the question of children come up in this conversation, although we know from covid that anything that impacts how children do anything in a systematic way has huge impact good or bad.
