I have worked in STEM for not quite that long. It does exist.
The guys running the lab do, in fact, grab you in the elevator. Just once. With the right response they do not do it a second time.
I have a friend who was asked to drop off her dissertation at her first reader's house. She did. In the reflection of the sliding glass door she saw him coming at her stark naked. Fast forward 10 years, she headed the committee from DC coming to review his laboratory.
There are men out there that don’t deserve the title of men. I’m sorry that you were treated this way and that person should be fired. I do recall one engineer that was fired for stalking a young co-op. I just don’t see this systematic rape culture that is described in her lecture, especially in engineering. The men I know and work with are not predatory monsters. I am tired of hearing this slander. I have worked in laboratories, huge corporations and small ones. If this was a systemic problem I would have witnessed something or heard something. I would have seen rapist arrested. I hope that creep who grabbed you is out of a job.
