Consult your lawyer.<p>I&#x27;ve attended a few sexual harassment training&#x27;s over the years. There are no clear cut rules. In fact, in my first training, harassment couldn&#x27;t occur until the other sex said &quot;stop, no, etc.&quot;  In the last one I attended, things aren&#x27;t so clear cut, and it seems like the lawyers have made sexual harassment so unclear that the only ones who can determine it are the lawyers themselves.<p>It doesn&#x27;t matter that it was after work, using a non-work communication medium. It still could be or maybe its not harassment.<p>You are going to have to talk with her and let her know that you have to act upon this. You don&#x27;t know what is going to happen. At a bare minimum, something is going to his HR file. At worse, a lawsuit is going to happen.
