Hm. My experience is that most of the time as responsibility is diffused in big organizations people are motivated to just stay quiet, weather the storm, don't rock the boat. And the typical "matrix management"-like organization structure (where everyone has many different managers, eg. there's a project manager, there's a technical manager (let's say engineering manager), there's a [human] resource manager, there's a team lead [a non-commissioned manager]) exacerbates this.

> even the team could fire their manager

This would likely help a lot with the Peter Pans who ended up promoted to managers but are terrible at managing.
