You’re overlooking that most managers don’t actually do anything, so they need desperately to justify their positions. I have a manager who has seven hours of meetings every day, five days a week. We make a fucking app. It barely changes month to month. What on earth are you spending 35 hours a week talking about?
The manager has so little to do they just micromanage everyone, and cause a massive backlog of work that doesn’t have to exist.
I always thought that Office Space was satire, but it really is like that in a lot of companies. I spent more time updating managers than doing actual work since I started this position.
