Alabama law specifically and in so many words gives the employer the right to claim the jury fee you earn from the courts. However,remarkably enough Alabama is also one of the very few states for which you must be paid for jury duty time.
Were you? I am not asking if you were punched in during that time; I am asking if you were paid for it.
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.
