For what it's worth - I've been in tech for close to 30 years and honestly met 2 or 3 managers that really did their job well and truly helped.

The rest got jobs from mergers, takeovers, friendships, time or lack of strategy/interest from others.

And what happened to the good ones you may ask? They all left the places where I was to grow somewhere else.

Management mostly creates politics (ghost & real ones) - I would love for management to truly help teams employees and projects - but they rarely do.

To be a good manager you need to manage up and down - but most only manage up...
