Just one person's perspective - but I completely agree with the idea of wanting to feel part of something and not getting that with 100% WFH. Most of us spend a good chunk of our adult waking lives working, we might as well try to make the time as fulfilling as possible. I get energized by being on a team and building something together. WFH is just not the same for me.

I know others can be fulfilled working from home, so I'm not advocating forcing anyone back into the office. But I could see a scenario where companies differentiate into pure wfh and 2 or 3 days/week in the office. I may be weird, but I would chose the latter, all other things being equal.
