It seems that modern society has made "standard" things more standard than they originally were.

At least people having special arrangements and working, say, one job 2 days a week and another 3 days a week, and the third sometimes on-demand, seemingly was more normal 100 years ago.

Of course not the majority, the majority would work their asses off by the clock even more than now.

But there are upsides to a non-synchronous, irregular life schedule. Say, more even load for utilities and transport. Weekends not being special days when half the things don't work.

And, of course, the ability to pick something you like most. Say, if the pay for 3 days a week somewhere is good enough to keep you floating, even if barely, then why the hell not, it's worth it.
