So I'm posting this here because I need to ask for help. I just got a job offer from the steel mill, and expect to start working there next month. It's a blue-collar job, and I expect there to be plenty of disparity between what value the workers produce and how much we are paid. So, I want to unionize. I'm currently in Australia, and last time I posted a question to the subreddit (My uncle is a politician, how do I convince him?), I got way more answers suggesting I unionize my workplace rather than try to flip a career-long conservative politician in a conversation. Unfortunately the subreddit got removed, and all the resources they gave me for unionizing your workplace got removed with it. So yeah, I'm here asking for them again, knowing that this time I'll use them, for unionizing, and especially unionizing in South Australia.
I wanna emphasize the "small victories" part in @SickleRick's excellent message. Have a concrete and popular ask. Something everybody wants. Then get another one. And another one. A dedicated break room. Some safety equipment. Some "minor" wage theft thing. Figure out what people don't like about the place and get a small victory. You can and should organize for workplace improvements before you have a union and use that experience and the connections you build to have credibility and support when it comes time to use the big "U" word.
