Most senior leaders have been there forever. Many are weak. Failed to scale as company grew up but refuse to leave or step aside. Middle management is full of politicians who get ahead by kissing up.
It is a difficult culture for anyone to grow in, but especially for women leaders. HR is useless and only exists to protect the executives. That's what happened in IT, where the head of the division protected all his male buddies while seeing woman after woman punished, demoted or put on a plan out.
It's ok though, we all moved on and Autodesk has the IT group it deserves now.
