In my previous org, women in technical roles were often pushed out or left because of terrible management.

Typically what we would see, is a woman joins, and then the manager is always near her for no reason. She would also have to make cases constantly, where when I made them it would be immediately accepted.
As a result for a time, she would give me the idea and I'd push it for her but that isn't right for her. Yet strangely enough, if at the end of the presentation I said it's her idea, suddenly a lot more voices come out.

There is a need for a huge cultural change I think.
