I suspect we'd see a bunch of change. A difference of when we moved 6 to 5 days is in those times most business were closed on the weekends + generally people were more tied to one company for longer term. Plus 2 days off is very different than 3 in terms of alternate work opportunity. From that a likely issue is a steep increase in people having second jobs so they work a 4 day job and a second 2/3 day job. I suspect the 4 day week will work well for people with good salaries and market power, but encourage working class to 'work the weekend' in alternate jobs resulting in lower downtime. For this I'd actually like a 4 day week but with it either more restricted business opening on Sunday type thing or significant wage multiples over 3 day weekends to encourage time off vs the 24/7 economy.
