The thing with these mandated back the office proles/peons is the lack of choice. Some people like the office experience. Some don't. It could go the other way where a company decides to save on office rental by forcing everyone out.
This CEO (wank puffin is my choice of insult) seems to have forgotten that happy staff are more productive. Let the ones who are happy use Zoom/Teams/Slack and let the social animals have their water cooler moments.
I'd be interested if his office door is open for everyone to 'talk to senior management'.
