For reasons I won't go into I'm not able to support strikes and such in person, but I am able to donate money to the workers if that helps. The problem is I'm not familiar with what sites or orgs I can donate to. I wanted to ask people here for help.
Holy shit... I spent a few hours poking around the internet... Its kinda difficult to find specific unions that are striking if they aren't making headlines.
Going to have to do a bit of research on your own, comrade.
Start by "union organizations in [state name]" and move down the list.
Maybe check local newspapers for mentions of labor strikes. Possibly use a throw-away account on reddit and ask for some leads specific to your area in the labor union subreddits.
