Well it's mutual in the sense that some workers consider WFH very important and others might not. If I interviewed for a new role and the job
demanded I be in an office 5 days a week then I'd have to consider whether it was a good deal, for example the pay and the environment.
Before Covid I worked in a low fenced cube in a big open floor office area. I did not have a private office. The noise and frequent interruptions and impromptu "meetings" of small groups in my area, made my productivity low sometimes, I'd even stay late from time to time just to get the quietness after most people left.
Can I work in that environment, sure I can but it's hard, hard to focus on complex problems and do deep thinking but if they paid a lot and I felt the money was worth the pain I might accept the job.
Here's some information on how damaging noisy environments are for this kind of intellectual work. Its from the book Peopleware by two industry experts. This was before Covid so is not "about" WFH but about the measurable cost of noise for people doing my kind of work:

These guys know their business and they talk about the huge costs that business incur when they don't care about noise, huge hidden costs that impact quality, timeliness, turnaround time and so on.
I passed this book around to several managers at my place, years before Covid to show that we could get some improvements if someone would reduce the density or provide some private office space for certain work at certain times that we could "lock ourselves away in" when very busy.
I did WFH perhaps a couple a days a month back then, informally and my boss said that was OK because it didn't get much attention so staff that MUST be in the office were unlikely to kick up a fuss. When I did that I could get HUGE amounts of work done.
When Covid came it solved the problem 100%, not only could I avoid the bedlam of a noisy office I didn't have to commute either, but I never sought to work from home, I actually was OK with driving in but having a very quite office that would have made my day back then.
But Covid came and I got not only serenity but no commute.
Software companies, good ones, know all this and that's why people at Microsoft, Google etc always got a private office each, they know that that generates maximum quality from their coders.
