Stanford Graduate Students Won Their Union Vote
It was a disaster at Wisconsin. Union favored the 8th year humanities students at the expense of the 1 and 2 year STEM students, and traded cash for benefits that really only affected people with families.   Stipends were the lowest in the country among major research universities, and  the union refused to let wages rise for in-demand TAs, so a bunch of them went off and got private sector jobs instead, limiting the size of the undergrad population.  Scott Walker killed it, and those problems haven't come back.
