Humus, the union is already involved. I think they're appealing the district's decision to fire the OP.OK, thanks for all the clarifications.
I don't think they will fire you. I think they will have to find you a position, since you have been there 6 years.
But if they do fire you - I think you will have to get the union involved, and a settlement would have to occur for their mistake. I can't promise that, but let us know how it plays out!
