Germany reporting in, couldn't see that becoming a thing here. I have about 99% wfh currently, and if my employer would try to implement something like that, the union would probably not even have time to get involved because the works council ("Betriebsrat", not sure if that's a good translation) would swat it down instantly.

It sounds insane, but believable for the US (but that might be my bias showing, I've always heard bad things about worker's rights in the US).
