This was my first thought, as well. I was middle-management in corporate for a bit, and you have hit the nail on the head. While in the office, managers have "some" necessity in keeping people happy working with each other, e.g., settling minor differences, squabbles, etc., before they become an HR issue. But, when everyone is working from home, managers become practically irrelevant, except as menial meeting coordinators, and attendance-takers. That's it. They lose their power, and they are beginning to realize that they cannot command the salaries that they once did. It's hilarious to watch.
