Yeah, you just have to know yourself. Personally I feel like I need to go into the office once per week otherwise work starts becoming an abstract thing. But I've known some co-workers I wouldn't see for months at a time that were really on the ball. Ask an obscure question about something really technical on slack and get an answer within seconds kind of thing. I knew another guy that said he had to come into the office every day because his family was too distracting.

Everyone needs to know what works for them and be a responsible professional about it.

And yeah managers that want 100% RTO are just admitting they can't handle working from home. Ok that's your thing, but it's not a thing for everyone else.

Anyway I got out the the RTO thing because I told them of the times some computers were having issues and I had to work the whole weekend (from home) to fix them. If I'm going to be 100% RTO then I'm 0% WFH and the next time something like that happens I won't be able to start working on it until 9am on Monday morning. So I'm still in the office one day per week, weather permitting, which is my preference.
