Everybody knows the fighters in the UFC are officially "independent contractors." So, my first question is whether this means they are legally prohibited from unionizing? If so, I will automatically have the answer to my second question, which is why no viable union has already formed? But if they are already free to unionize, what's the impediment? I always hear about the top fighters not joining in, but why should that be decisive? Everybody else could still unionize anyway. Even though I'm mainly thinking about the UFC, it occurs to me that a union might need to be industry wide, or at least across multiple organizations. This is because fighters are constantly leaving one organization and signing with another. Another thought, team sports wouldn't appear to be a logical model for a MMA Fighter's Union. Would it need to be similar to the PGA or The Association of Tennis Professionals?
