Kinda wish I spent more time with my coworkers and tried to work towards a union, even though I was a contractor. Not sure if I would have been successful because my coworkers were pretty right-wing and anti-union. Perhaps after trucking and after I save for and attend school and become an electrical engineer, I will try to talk to my coworkers more, organize board game nights or help support my coworkers when they need help in their personal lives, hopefully build solidarity and community, and eventually educate them and push them towards unionization.
There were some good tips in this blogpost I hadn't thought of, and it would have probably helped me in the past.
