The recent wins at UPS will no doubt inspire other workers and provide a practical way foward for their liberation. However I do take issue with how unions from Teamsters to the SAG-WGA don't leave many channels for public feedback. I can't even join the Teamsters if I'm unemployed. And revolutionaries of past have made criticisms like this.
Rudolf Rocker wrote an entire chapter in Anarcho-Syndaclism- Theory and Practice about how trade unions didn't think and beyond the needs of their own, especially negating to engage and unite with the unemployed.
Not at all trying to cancel UPS workers, as the issue is beyond them. In fact, we should look to organize the student debt strike for the end of August 2023 that inherently incorporates both the employed and unemployed under one campaign.
