Unions served their purpose a long time ago, but now merely exist to grab as much money as they can without giving a shit about the consequences as well as to pay exorbinant amounts to those running them.
Yale has unionized cleaning staff, and while I worked in two different finished buildings there doing renovation work as a union carpenter, their staff would work for approximately 2 hours of their 8 hour day on a good day and spent the rest either sleeping or congregating where they knew a 'boss' wouldn't find them and just bullshitting for hours. It was the biggest joke I've ever seen.
My union has our local's president driving an expensive sports car, the union cutting benefits and pushing up the age for retirement to get your full pension, whilst we had over 1400 members out of work across the 3 locals in the state.
Unions for a long time now stopped being a good thing and are now just a money grabbing operation that exist to increase wages far higher than they SHOULD be, especially for people who don't deserve a job in the first place.
