I don't have to imagine that I work in it every day, I think it's pretty standard to have a few A students a bunch of C students and a few F students. The problem with the union is the F students don't get fired and if they do they just move them to another open slot assuming they have seniority. On the plus side you're not going to get replaced at 45 by some low-end college grad because they'll work for half the price, is job security worth carrying a little extra load?
