No surprises here. After the NLRB ruled that graduate students were employees, Columbia University students voted by a margin of more than 2-1 in favor of unionization. here
Of course, within 2 or 3 years it is very likely that the "Trump Board" will reverse Columbia University and return to the holding in Brown University (that students are not employees).
Welcome to politics as usual at the Labor Board. My students are all very familar with political influence in NLRB cases. This is just another illustration of why elections matter.
