In Europe I believe you can request an 80% work week, I've seen job posting and heard it second hand. Here's a Swiss example, https://threema.ch/en/jobs#openings of 80-100% jobs
In North America there were and are a number of companies that operate or operated (pre-layoffs etc, ZIRP free money RIP) on a 4 day work week. You can search "4 day companies" and you'll find a list. Some companies still operate on a 4 day week, so it wasn't necessarily a ZIRP-era only thing.
US congress or someone in government proposed a 32 hour work week -- unlikely to be passed of course or get any traction any time soon.
But in general, there's growing mainstream sentiment towards trying and exploring shorter work weeks.
If AI/AI-enabled-capitalists doesn't enslave us, those grandiose promised AI productivity gains may push sentiment further in that direction.
If anything - the US and, the majority of the world with it - has moved to longer work hours with fewer holidays. Sabbaticals are virtually unheard of anymore. Two people in the family work instead of one. I would argue the world is moving in the opposite direction.
