Here's an idea.
Have her file for benefits and see what the state says. There is no penalty for being wrong; it does not cost anything except a little time; if the state says no, you're no worse off than if you never filed in the first place.
Two things I am tired of typing: 1.) A wrongful termination does not mean that you were fired for something you didn't do; it means that you were fired for a reason prohibited by law. 2.) The above answer, whatever it is, assumes that no legally binding contract or CBA expressly says otherwise. If it does, the terms of the contract apply.
