Yea, I don't think there will be a fighters union either. I do however think the Ali Act will be applied to MMA eventually. It's only a matter of time before someone at the level of GSP, Rousey, or McGregor take the UFC to court to have the Ali Act applied to their contracts. GSP was the closest we've come. When he came back to fight Bisping, before the details were finalized, he wanted to re-do his old contract. Obviously the UFC refused at first, and so he hired lawyers. This was inevitably marching towards a court case that would have brought up the Ali Act, but in the end the UFC relented and they worked out a new deal. Sadly, it would be such a long, drawn out battle that only the wealthiest MMA fighters could afford such a court case. And in the end, the UFC will always relent if they have any real sense of a court case bringing up the Ali Act.
