Maybe? I can't imagine an office so toxic, so sexist an abusive that like Steve, Jack, Bob and Frank can come back from their 3-whiskey lunch and just go down the line asking Janet to show them her tits, asking Jessica if she does anal, asking Millie if she's ever done a girl, just over and over without the entire place in an uproar. Of like security guards getting involved, bosses firing people on the spot, women pepper spraying motherfuckers. Maybe it is, maybe Blizzard and the guys who work there thought it was a free-use social setting where women literally couldn't say no.
But it seems so over the top and aggressive to have happened even once without a massive shitstorm involving a bunch of lawyers, the police, firings, charges, compensation, etc...its not something HR can "look into" and find "no evidence of wrong doing".
