That's a really hard judgment to make, so far removed from knowing the circumstances of what occurred. Sexual harassment occurs along a continuum in which some women are groped or some women are called on the phone all the time. There's just a whole range of harassment.
Here's what I do know. It's always better to have some sort of sanctions for the offender. It can't stop there, however. The woman continues to work in a workplace then, where perhaps people have become alienated against her. Maybe they're friends with the offender and they'll ask why she reported him. They'll say, “Don't you know he has a family at home he has to take care of?”
