Very similar experiences here. My first job was in a union shop, but you could not be forced to join. Whether you joined or not, though, you had dues taken from your pay. I refused to join initially because I could choose to join at any moment, it wasn't a locked decision. I immediately had people trying to convince me to join, while within months of working there I realized how little pride or effort anyone took in their work. I worked at that company for three years and never joined the union, which apparently made the management think I wanted to be in management because they kept trying to promote me. I never wanted to be in management (then). I was easily 6x as productive as anyone else there, and I saw lots of really ridiculous petty corruption take place amongst the union members. Really soured me on unions, despite the general high level idea being something I agree with. I can't imagine ever joining a union.
