*tiptoes into this thread*
I would imagine that with any HR incident, there would be an investigation into what happened, with all parties involved being interviewed. The accused party could be put on either leave with pay or leave without pay while the investigation happens.
I don't know much about Equity. However, I assume they have some kind of process, and rules about what a performer can or cannot be fired for, and what needs to happen before they reach that point.
