Anyone Know a Good Labor Attorney?

So rather than go out on a high-note here at my soon to be former SLAC, it's going to be a struggle. I'm still working to get paid what others were for a canceled class from last summer (the university incorrectly canceled classes, and when the mistake was pointed out, paid $1,000 to all the faculty this happened to except me because mine was a graduate course).

This summer, when I pointed out that I was in the same situation that caused the courses to be erroneously canceled in violation of the union contract last summer and that I expected the university to adhere to the contract this time, I've been informed that even though I'm teaching two summer courses (they've met for two days now), the union contract doesn't apply to me because I gave my letter of resignation. Of course, things being what they are, I was never offered a different contact to work under.
