What kind of fucking reaction is this ?

"What about our families"

Yes, quite.

Women simply aren't conditioned to put their own needs first.

if she did that to him, sorry

Mosman, women are socialised to care more about what happens to men than about what happens to women, so L has probably been socialised to worry about his job and family more than you or even herself. Also, we are taught that we are responsible for men's behaviour and men's welfare, so she is taking on that responsbility.

This is true even of rape victims; I remember a friend telling me that when she was raped, when she fleetingly thought of reporting it to the police, her instant panic response was how awful it would be for him to be accused of being a rapist and how dreadful a person she would be if she did that to her.

Don't be too hard on her. She's obviously young and hasn't realised how deep-seated her social conditioning is.

You could talk to her to point out that any consequence for him and his family, is not her fault or your's; it is his. Ask her how she would advise a friend at another company, who was going through the same thing. Would she advise her friend, that the life and welfare of the man who was harrassing her, was more important than that of her freind? Or would she think that her friend was entitled to be in the workplace without being harrassed by someone who hated her just because she was female?

L may not wish to instigate a complaint, but as a colleague who has worked with the man concerned she will no doubt be questioned by HR about her experience of him. I don't suppose she will care to lie outright so the facts of the matter are likely to emerge then.
