The history of employment law suggests this is not the case. See for example:

> Josey quickly befriends several other female workers at the mine and soon realizes the women are constant targets for sexual harassment and humiliation by most of their male co-workers, who, like Hank, believe the women are taking jobs more appropriate for men. The union in real life was USW, and did nothing to stop it. Josey in particular is targeted by Bobby Sharp, her ex-boyfriend from high school. Josey tries to talk to her supervisor, Arlen Pavich, about the problem, but he refuses to take her concerns seriously. The women experience additional harassment and even abuse in retaliation, and Bobby spreads rumors that Josey attempted to seduce him, leading his wife to publicly berate and humiliate Josey at Sammy's hockey game. Sammy begins to resent the way the townspeople treat them and comes to believe the gossip about his mother's alleged promiscuity.
> Josey takes her concerns to the mine's owner, Don Pearson, but despite his previous assurances that he is there to help, she arrives to find that he has invited Pavich to the meeting, along with several other executives and offers to accept her resignation immediately. She refuses, and after Pearson implies he believes the rumors about her promiscuity, leaves devastated. Later, after being sexually assaulted by Bobby at work, she resigns and asks Bill White, a lawyer friend of Kyle and Glory, to help her file a lawsuit against the company.
