The head of United Auto Workers, Shawn Fain, has declared he will unleash additional strikes across manufacturing facilities of General Motors Co., Ford Motor Co., and Stellantis NV on Friday. This move is contingent on the three automakers not properly addressing the union’s demands for a new four-year labor contract for its 146,000 members.

“Either the Big Three get down to business and work with us to make progress in negotiations, or more locals will be called on to stand up and go out on strike,” UAW boss Fain said in a YouTube video published Monday evening.

Fain said, “We’re not waiting around, and we’re not messing around. So, noon on Friday, Sept. 22 is a new deadline.”
