It takes no more evidence these days, with practically any HR department, than a claim that some sort of racism or discrimination is “perceived”. Facts and reason are irrelevant. I have seen this, though fortunately not as the hapless individual against whom such a charge has been made.

My point was she will only get a few times to cry wolf and the company will find a way to get her out the door before wasting HR time and resources anymore on this nonsense...
