For some reason the Public Service Loan Forgiveness program forgiving gov't loans doesn't allow you to work for a labor union. Does anyone know of a way to get around this(i.e. still work for a labor union (or perform work that significantly affects them), and still have your loans forgiven)? As in, are there closely related employment positions maybe in gov't or non-profits that work hand in hand with unions where I might still qualify for PSLF?

Thanks.

The NLRB, of course (though if you're a 3L the application period for next year's honors program has passed).
