Good for her that she got her job back, and with all back pay included. But that school still does not want her back.
She would realistically be better off looking to transfer to another school.
The School officials at her past job won’t forgive her for outsmarting (and exposing) their bias, or for overturning their decision. They would very likely get even in petty little ways, or push her to accept early retirement.
You’re right. The bureaucrats will find a way to screw her.
