The UAW won’t be fighting its next battle alone, either. One of the most interesting aspects of the new UAW tentative agreements at Ford, GM, and Stellantis is that they are all timed to expire on April 30, 2028. If those contracts expire without reaching a satisfactory new deal, the UAW will be ready to strike on May Day, otherwise known as International Workers Day.
…
What’s more, the UAW hopes it won’t be hitting the picket lines alone. Fain has called on other unions to time their contracts to expire during the same period and “flex [their] collective muscles.” No, you’re not imagining things — the head of a major US labor union is calling on the rest of the movement to come together and start planning a general strike.
This article makes it sound realistic. It would be several parallel strikes by unions across various industries. Leadership is always the struggle for these causes, and the plan discussed here is handling that perfectly.
Oh yeah this action specifically is totally doable, I mean the broader political context and labor as a political faction that breaks through the partisan culture war.
