I learned early on that when you reported an incident to a supervisor, usually a male, you were viewed differently and there was a reluctance to believe it. And absolutely no skill or understanding of how to deal with it, even a good boss.
Early on, there really were no legal protections. So you learned to suck it up, protect yourself, deal with things as they arose and not use the system because the system was unable to deal with it.
Even some very decent people had difficulties. It was simply beyond their solar system. It makes me sad, that even with progress these basics are still an issue for women.
I do know that not speaking up allows situations to perpetuate, but on the other hand, without protection, you become the problem, end up losing a bunch, and still nothing changes. So we all dealt with one incident at a time, as best we could.
