It's a stretch to sell this story this way.
The employer says she was turfed for poor performance (at the old job), and because she wasn't a cultural fit at the new place and they didn't need a person in the role she wanted. She says she got the shaft because the people in her workplace couldn't handle working with her and she took a lateral transfer just to get out of there. Let the arbitrators deal with it. I have some empathy for her situation, having had a similar experience with a manager who seemed to want to make my life as unreasonably difficult as possible (although I'm only average-looking) and which resulted in me taking a large step backwards (in pay and seniority) to get out.
Whether her assertions are correct or not, based on what's in the article it seems as though the corporate culture at the place she worked at isn't exactly healthy or helpful (unless you're a man). She might have made a few political opponents in the workplace, and they may have been able to squeeze her out accordingly. After she moved, it was a matter of business need versus what she felt she was entitled to - but she was only in that position because of how the first workplace in the same company operated.
