I think many people changed the way they view work in general.
The pandemic made people very aware of their mortality and gave a kind of "you've only got one life, so you might aswell live it" kind of attitude, where work is nothing more than a way to bring some money in.
So even though people returned to work, I get the impression they don't have the same enthusiasm they once did.
Brother in law went a bit like that after his accident at work.
Basically does what the job requires, but won't push himself too hard to do more than that unless it's beneficial to himself/his operators by making things easier later in the shift, basically "it's not my job to clean that mess up and it's not a risk for us, so we'll keep doing our scheduled job and not try and do that as well" (on the flip side if his machine is down with an issue he can't fix, he will try and check on other machines and do things like get the materials for the new jobs ready)..
People basically realised that in a number of jobs "working extra hard" does nothing for you personally, especially in companies that have "downsized staff" without reducing the overall work/improving how they work or will just dump more on you, and that actual time with family was in some ways more important than a minimal extra income, or I suspect in some cases, it saved people money if one of the parents was able to cut their hours permanently (I know a couple of people for whom pre school age childcare costs meant they were actually losing money by both working despite both being "professionals" and that was with the discount they got because the wife worked in the school that had the nursery).
