I took a quick look through your profile and your audience is small and you generally get low engagement but you seem earnest so I would love to help you get involved with organizing. The good news is you don't need your audience! The fastest and easiest way to get involved is to contact SWU.

sbworkersunited.org is their website. Contact them, tell them where you are and that you want to get involved. They should be able to tell you where and when you can join a picket line. You don't have to be a member of the union. Keep showing up, talk to them, know the people in your community

Bring a friend, keep bringing that friend. As your friend gets more committed and gets to know your new friends at SWU you both bring to new friends.

Talk about the time you spend on the picket line in casual conversations at work, with strangers in line at the grocery store, wherever it makes sense. Don't be preachy about it, just describe what you're doing, share interesting moments (protect the identity of strikers). Normalize it in your life
