I'm guessing the "student" part of "graduate student" is the confusion.
Fyi... grad students are also employees of the university. So a labor union applies to the "workers" aspect of graduate students. Grad students get paid a stipend (salary) for research, teaching, etc. It's a "workers union" and not a "student union".

2. Get dental insurance for the students. Almost no US graduate school offers this.
That said, to a graduate student, $3k can be a non-negligible amount of money, and the school is likely kicking in money to pay for the plan. In my position, if my company didn't subsidize the plan, I'd be happy to just go without.

Eventually, Pournelle’s Law Iron Law of Bureaucracy takes hold and the purpose of the union is to strengthen the union regardless of the needs of its members.
Labor labors are an established thing. If a union is approved by the government, then they would have protections.
TAs striking has been somewhat effective, but RAs mostly don't actually strike.
Failure to accept feedback makes for a fragile institution. Since the students decided to unionize, clearly their issues are not being heard, and a union will have a much stronger public voice than any individual student, perhaps on par with the university's brand and PR campaigns.
