I don't think what DeeDee did was harassment, unfortunately it can be such a subjective thing, because it has to do not ONLY with what is said, ...but also how it is
perceived and how it makes the other person feel. And we all know men are NOTORIOUS for misinterpreting friendly cordial behaviour from women to mean
'she wants me'.
If it is specifically written in the HR policy at her workplace, and it makes him feel uncomfortable and he complains about it, Deedee could land in hot water. Hopefully sanity will prevail.
Sexual harassment also does not require contact, the desire to have sex or to imply such either. It can simply be unwanted or hostile attention focussing on a person's gender. ie: When furious over someone's incompetence, losing it and screaming that
"your f-ing problem is your bra size is bigger than your IQ." is a definite no-no and is considered sexual harassment even if said from one woman to another and only in the presence of other women, it's still sexual harassment.
Comments designed to demean or humiliate a person based on their gender is also considered sexual harrassment as well.
Then too are the idiots who just go too far. Try playing a prostitute on a film set with a bunch of horny IATSE crew members and a set full of meisner trained actors.
Usually the crews are pretty professional and try to keep it to themselves, ...but sometimes the actors can be just craaaaaazy!.
Bottom line however is, sexual harassment exists in all shapes and forms, and it plays both ways.
The key is developing a good enough relationship with the other person so that comments, jokes, etc., are not misinterpreted, and boundaries are not crossed, ...and knowing when to leave well enough alone
I think pretty much none of us can be considered completely innocent when it comes to sexual harassment either intentionally or unintentionally at some point or other, ...but few of us are guilty.
