> And from the student perspective, the recent votes at places like Chicago to unionize (and, more importantly, the justification provided by the student groups that organized those votes)

I'm at a school that underwent a grad student unionisation drive, and pretty much everything that the union proposed would have amounted to further empowering the administration at the expense of the academics (e.g. introducing new mediator officials with extensive compulsive power over advisors if their students should feel wronged in one way or another, hiring more staff to enforce diversity-friendly admissions and hiring outcomes, ...). At least the politicised end of the student body seems to consider the administration, rather than the academics, to be their natural ally.
