Anecdotally, my company did a survey (10k+ employees) and the vast majority didn't want full-time work from home in perpetuity.
I think it works well for some industries and functions, but it's an absolute cluster for others. Add in the inevitable "COL adjustment" for people who live in LCOL areas, it will be a few percentage of employees who make a permanent change.
Once Covid is a thing of the past, we'll see the vast majority of people return to work in an office - likely with a lot more "work from home" flexibility, but still an expectation that they are in the office for some percentage of their work week.
Just my 2 cents. I could be entirely wrong.
This is because they have found WFH to be so successful.
I am honestly somewhat wary of this. It seems like execs saw the dollar signs flashing and are starting this, yet we barely have any data on this affects levels of productivity. It hasn't been that long for them to get that data.
I've had remote-only jobs and jobs where I went into an office every day, and I have many more pleasant memories and longer-lasting relationships from the jobs which had an onsite component.
