To be straight I doubt she will make it official. The problem with accusations (even if they are of the non-racist sort) is that management will always side with the accuser, even though there is no concrete evidence. They do this to protect their own positions and to hell with someone's career. I have a few friends who have had to resign over unsubstantiated claims, even though they have 20+ years of dispute free employment. In their cases none of the accusations were in the racist vein, but cowardly brass hats protected their asses by taking the easy route. As per usual, feces always sides with gravity.
