But why? If they are not scholarship athletes, then how is it different from any other student who gets a campus job?
Every on-campus job is subject to Title IX. If the school didn't allow women to hold certain positions in the book store, they would be in violation of Title IX.
Title IX is not an NCAA thing, it's part of the Civil Rights Act and merely states that no person, on the basis of sex, can be discriminated against if they receive Federal Financial Aid. The U receives financial aid and therefore they cannot discriminate on the basis of gender.
Like all well-intentioned government actions, that simple concept was the seed of this bureaucratic mess/utopia (depending on your opinion). Title IX isn't cooked into the NCAA and athletic scholarships, the Title IX offices are the judge, jury, and executioner for accusations of sexual assault amongst college students. It's grown to be an all-encompassing force on college campuses.
The interpretation of Title IX, in the NCAA, is what lead to the requirement in number of scholarships, financial backing, etc.
Right now, there is a lawsuit in Oregon , where female students are suing the U of Oregon because they do not believe they have the same NIL opportunities as male students. Mind you, all of the NIL $ is coming from private entities. Their argument is essentially that U of Oregon, is giving more NIL opportunities to men because the private entities are really just a proxy for the Universities.
Sorry if that was way more than you wanted and I am not attempting to derail the conversation into some political debate about Title IX. However, it was hard to explain without some background that Title IX would still rule if any funds are coming from the University (and potentially even if they aren;t).
