Honestly idk if even 50% of that 20% care. Maybe nobody cares! It's all good. :)
My guess was that a lot of the management demanding people to return to the office, are the kinda people that want to be around a lot of people, so they ask everyone to come back so they feel better. That's all.
I don't know where I fit in all this. I went full remote and at my company they don't allow everyone to do that - it's more of an "ask your boss and maybe they'll let you" kinda thing lol.
I'm not even an introvert. At least, I don't consider myself one. I like being around others and chatting and socializing and stuff. I just don't care for the expectation to be there at the same time for many hours every day. My office is big and noisy and there's a ton of people in the room making noise. It is distracting as hell.
It's also not in my favorite place to hang out. It's a kinda boring commercial area on a busy street with no good places to walk or hang out outside the office. IDK. I do visit sometimes.
