I disagree. Your anti-corporate bias is showing through again. While that might be true at some firms it is definitely not true of all of them. HR and other management officials at a number of companies certainly will act when given solid evidence of the wrongful behavior. As you don't know the people at the firm she works for, you are not really in position to flat out say that HR "will not help you." It might, and she probably should start there with the evidence she gets, and then escalate it from there if needed.
