Let's break it down for you.
Starting around 1978 Jack Welch reniged on the contract workers had with companies. Before him, American workers union or not could expect to work at 1 company till they retired. It's called job security. We don't have it? That's why we aren't having kids. Let's the CEO's have all the kids. They can afford it.
Since that time CEO pay went up 1322% our pay 18%. Wake up
In that same time the percent of workers who belonged to unions went from 35% to 9%.
How come wages went down with union membership? I think you know the answer to that fool.
