Open Labor is currently an informal group, so “joining” is a notional thing. When we have events and discussions we send out a Mail Chimp email. So sign up.
We have a small core group of activists, a few hundreds of key supporters, and thousands on our subscribe lists. So, pick your position and make yourself known: write an article, a comment below the line, an email, a tweet, make a phone call, makes some new friends, or do it all. And that’s joining.
