As we said, there is a lot more to it than this one incident
Which you don't appear to have read either. Why not?
It is the pattern of behaviour which is telling here.
By the way, "exploiting of a junior" is perfectly possible even if she appeared willing. It's the fact that he was over 40 years older than her, in a considerable position of power and she was meant to be his employee and he had only just met her, plus the gaslighting, before having anal sex with her. That's by definition abusive. Do you HONESTLY not understand that? And that people can be abused even if they say "oh yeah, it was great." You don't get tha?
Did you look up what a "fawn" response was, btw?
And can you honestly understand the coercive, abusive power dynamic there?
As others have said, that dynamic would get most employees sacked.
Since it is repeated with multiple other women and over many years, there appears to be a pattern. Once again, you don't seem to understand a great deal about coercive relationships, problematic power dynamics or grooming.
Weird.
And best ignored, I think.
