Don't get lost in the wave of calls for far-fetched, ultra-radical actions that will never materialize.
Start small. Organize a union at your job. Fight for realistically achievable demands: wage increases, stable hours, whatever you need.
When people focus on taking things seriously, by actually starting small and focusing on the long-term game, that's how one day you build up to doing something big.
Don't just walk in your job and say “union” and get fired, but actually look up guides on how to subtly promote it, slowly convince people, get in touch with a bigger labor union, get help from their organizers etc.
