This is how the so-called unions work. The chosen few form their own elite complete with privileges unavailable to the members, and in time begin to work for themselves as just another elite, and so against their own members.
One is seeing this with some unions in Germany now, as the union elite sellout the rank-and-file for their own connections and betterment. One observes that this sort of thing in endemic in PUBLIC sector unions.
I remember an NBA strike a number of years ago. The negotiations were run by top players and their agents. The lesser players, and especially the bubble player were thrown under the bus.
