The Importance of a Collective Bargaining Agreement in MMA

Would you prefer the passing of the Ali Act for MMA fighters or fighters union, in which case the fighters or employees of the UFC with a CBA? I mean, the argument is that if you had a union, first of all, it'd be very difficult to get one. The way in which the union works in a league where teams are bidding for services is not the way it would work with the UFC. And by virtue of that, the amount of concessions you could draw at the bargaining table would be somewhat minimized.
