Oh...I am with you IRA...its wrong. It undermines the union and ability to negotiate a deal in good faith. I'm on your side with this. I am just not sure anything is going to happen until the bid closes.
Also--if the union hasn't already stood up to fight this, then I have no idea how the process gets started. My belief is that someone will have to file a grievance. I think Edgar would be the proper guy to do this...
