@engineer,
This interests me. I worked at a major hospital in the science lab(s) for a lot of years, but met my future husband after six years, which stopped my dating anyone else, happily cold turkey. During the time I did date some I worked with, nothing horrid happened - indeed, I still count them as friends and have fond memories, and that was a long time ago now. No ugly approaches, nothing insulting - and I was a sort of early on feminist. Ok, I shook my head at feminism in '62, but read more and agreed at least somewhat by '63.
The only harassing in all that time was just plain funny - Jimmy the Flirt, easily dispatched. Even Jimmy knew he was playing obnoxious. He was keen since we had the same exact birthday (snort). That's true but so what? He's old too by now....
Well, I've been talking the late 60's/early 70's. Maybe it was, at least sometimes, a loosey gooseyer environment at that place and time.
As I've told on a2k, I was raped once, not at all funny. I should have gone to the police, but that was beyond my ability then.
That was before the times I described above. Maybe those times above were a cure of sorts, attitude adjustment in action.
I do understand the wisdom of not dating people at work and likely have advised people on a2k not to, for the usual good reasons.
