"If we don't make serious progress by noon on Friday, Sept. 22, more locals will be called on to stand up and join the strike," Fain said in a video posted by the union Monday evening. "Autoworkers have waited long enough to make things right at the Big 3. We're not waiting around and we're not messing around."
Fain didn't say how many additional plants would join the work stoppage, which began Friday. His comments suggested that the UAW could decide not to add plants even without deals in place by Friday, so long as the union is satisfied that the talks are productive.
