That is bizarre, almost disturbing behaviour. I am not going to comment on the case at all but for me several details from this article cast a very strange light on the whole scene, and that one just takes the cake.
I was not there, but taking the post at face value, it was right for Joe to be dismissed. His behaviour was inappropriate and unprofessional. The company's whitewashing was also regrettable. But I have difficulty dismissing the notion that the rather extreme reaction from Justine is indicative of some underlying issues she might have. I concur with the top-voted comment that she may benefit from therapy.
What Joe did was wrong, yes. But there is no line that connects that dot with Justine's boyfriend tying his fucking ankles together while sleeping on a couch. That is something else entirely, and I stand by what I said.
