I'm not smart enough to fully understand all the implications of how unionization and title ix could be at crossroads but I've read a handful of articles that have said it will have to be hashed out and there will be title ix challenges/lawsuits.
SI: We’ve talked before about Title IX implications. What happens if the bargaining unit is ruled to be just football players, who are male athletes?
MM: That’s a great question. If it’s only football players, and those players negotiate contracts in which they’re paid something, then there will be female athletes and attorneys undoubtedly arguing that this is a violation of Title IX. Even though Northwestern is complying with one area of law — labor law — it would be in violation of another area of law: Title IX. There would likely be a Title IX challenge forthcoming. The size of the bargaining unit could play a big role here. If it doesn’t include female athletes, a Title IX challenge will likely occur pretty soon.
