Personally, I’ve always loved the process of taking things apart, understanding how they work and putting them back together. I turned that into a degree in mechanical engineering and eventually a career in power plant operations. Couldn’t be happier with my work than I currently am. Its WORK but I don’t hate it and I feel like I’m doing something important.
Unions are made up of human beings, and unfortunately most human beings suck. Unions are the only way we know to fix bad workplaces though.
I know, I like/support them conceptually and hate them in anecdotal experience.
