It’s not mainly “corporate real estate” or “getting people to quit” that motivates CEOs. Regardless of what your personal experience, CEOs do not own the building or want to spend money on hiring. They legitimately think that “meeting in the hallway” is a good idea because that’s the only time they spend listening to the little people.
You know that you can just ask someone for info like a normal person, but they are legitimately isolated. Many people freeze up if they get a call, email, Slack message, whatever from the Executive Team. CEOs need leadership training to manage remote workers.
