I've seen some parents on Twitter looking for videos and books about the labour movement for their kids who aren't crossing the picket line. I recommend watching for any adults, but I don't know what age group this would be good for. So far, I'd be comfortable showing this to anyone 12 and up, or younger if you have a particularly sensible kid. I was obsessed with Newsies as a kid and this would have been perfect for me earlier than 12.
Feel free to add more videos and book titles/links in the comments. This is important stuff to learn if we're going to save the social safety net and have an equitable response to climate crisis.
