I've found bad managers are able to exist, even thrive, due to a culture of loyalty. Having worked in several countries this is a very Corporate America thing (IME). Loyalty is the only trait that matters. Fealty might be a more accurate description.
So that bad manager's manager looks at a situation where people are leaving. Those people are disloyal and thus bad. The bad manager is completely loyal and thus good.
Seriously.
Most people don't care at all about doing a good job. They just want more money. To get along with them, you must help them get more money. If you oppose them on anything, they will make you suffer. And if they have the skills, they will manipulate and gaslight you. You can't make anyone do their work well. People work well when the organization is set up for it. If you can't tolerate your teammates' behavior, just move to a different team or company.
Why they had to invent "to be the best employer of the world" as a leadership principle?
The more people should stand up and make the stupid policies known, that's the only way this can stop. Otherwise this policies will be the norm for many companies since "it can work"
The only thing that management cares about is how much they're paid, and how much power they have. Look at how Elon Musk behaves. He gets mad/irritated when told by regulators that he can't exercise the power he feels is his right. I actually don't think he gives a hoot about how much money he has, except as a tool for accomplishing what he wants.
Others are more into the wallet than the ego. Do you think Zuckerberg gives a crap about what privacy advocates think? Most people have a fair idea of how far FB spies on them, and Zuck knows they don't care as long as they can share cat pictures with their friends, or post Let's Go Brandon stuff. But you can bet that he's supremely pissed about losing so much money due to Apple's privacy changes.
There are very few Senior Managers who take the time to look beyond what’s immediately presented to them.
Have I described correctly the situation?
Legend:
M2 - senior management, has other managers reporting to them
M1 - first layer of management, has workers / engineers as direct reports
