has been no better time than now to come forward. And, it doesn't need to be announced publicly; the accusation and investigation should be handled privately.
There is not a legitimate company in the world that doesn't take these sorts of accusations very seriously, because the potential for massive lawsuits is huge. If anything, companies give them more credence then they often deserve. I've seen careers ruined for unsubstantiated accusations, because it's easier for a company to get rid of an employee than deal with a potential hostile workplace lawsuit.
I have no idea what industry you are in, but males are pretty much emasculated on day 1. I'm not saying sexual harassment doesn't exist, but it's not prevalent. There are other forms of harassment more prevalent yet less tangible.
And, finally, my question is really just when is a line drawn? What is a person's moral compass? That's always my problem with ethics classes college courses now make everyone take. This is the kind of stuff no one can really answer until they are faced with it. Do you lie to a customer make sure you hit a quota and maintain your job? It's always easy to answer that in a classroom setting. When you have a wife and a couple kids depending on you, things change.
