I don't quite understand that either. I was sexually harassed when I was 16 from my boos when I worked at a McDonald's restaurant. However, six months later, he was fired. I don't know what happened to him besides that. But he got fired for sexually harassing the girl that replaced me after I quite. I was too scared at the time to press charges. I just wanted to move on with my life.
I regret it now because it happened to someone else. But I was just a kid back then. And I grew up being abused by my Dad, so I was very scared to speak out about anything. Took years of therapy for me to realize that I am stronger than I thought I was and that I am able to speak out now. It's never too late, as long as you tell your story and help others to be able to do what you weren't able to do.
Supporting others is the best thing you can ever do for someone.
