I am sure the school is trying to placate both sides: the parents, and Ms. Klug. I expected something like this would happen and while it could be worse (here is a list of substitute teachers the school could choose from and they could have reinstated her and just never called her again), they will keep her busy until the end of the school year which is not that far away, and then they will be free to not continue her employment.
I do not understand why people (as a majority) attack what they do not understand. I wish Ms Klug nothing but the best. I sincerley hope that she is able to fulfill her dream as a pilot.
