How is she still getting hired? Is she lying about her job history or are schools that desperate?
AFAIK, she left schools off her resume. Jewish schools also only confirm employment, they don't discuss the performance.
FTFY
No thank you. I think that there is no reason to refer to someone in a manner they do not wish to be called. So if she wants to be called she, I can do that. I also don't call people by nicknames they don't like or even by their full name if they don't like that. You can be kind to someone even if you don't agree with their choices.
