This is a well written piece.
Case by case, there may be good reasons for teams to work together in person. As a general rule, though, it turns out that ordering people back to the office full time is a power and status move. It’s a signature strategy of leaders who exhibit narcissistic qualities. They see any kind of remote work as a threat to their authority and admiration. They want to be worshiped at the office altar.
TL;DR: it's about swinging their dick around.
