Goes a bit deeper than that, Cassie. Way, way back when the union movements began just about all over the world, there was organized opposition to them. Most trade unions came into being during the great Industrial Age on the 19th and early 20th Centuries. The ideal was to get better wages and working conditions for the people the unions represented.
This was fought tooth-and nail by the big industrialists. They, in turn, hired thugs to put down and intimmidate the union leaders. In many instances they even saw to it that those leaders were done away with - killed in some instances. I believe there was a wholesale massacre of trade union leaders by such 'hired gangsters' on a ferry boat somewhere in America in the 1920s or 1930s.
It got so fire was fought with fire. It was only after long and arduous conflict that here in Australia Aussies got the 40 hour week, paid recreational leave et cetera. It didn't come about out of the kindness of the hearts of their employers.
Study your history. You might be quite surprised who the 'baddies' used to be.
