I was a boss for a couple years. I didn't force anyone to come in but I did find that I got along better with the couple of people who worked out of the office just because it's easier to see someone as a person when you can sit near each other and BS all day as opposed to the ones who worked from home and I really only talked to when we were in meetings about work shit. I tried not to play favorites but that aspect did probably bleed into things a bit. We had a team chat going but only a few people used it (or they had one that I wasn't part of so they could talk without the boss looking over their shoulder, which is fine but it's hard to get comfortable with people you rarely interact with). I'm now on the other side of it with a boss who always works from home while I'm in the office and I'm struggling with that a little too because I have a hard time gauging if they're upset with me or if doing well when we only talk on the phone a few times a week.
