"Tonight for the first time in our history we will strike all three of the big three at once," Fain stated in a Facebook live broadcast. He singled out the General Motors facility in Wentzville, Missouri, the Stellantis plant in Toledo, Ohio, and the Ford plant in Wayne, Michigan as potential targets for retaliatory strikes.

Production at GM, Ford, and Stellantis, which assembles vehicles for the Jeep, Ram, Dodge, and Chrysler brands in North America, might come to a halt even if only three local unions went on strike.

Strikes are risky business for the union and the public at large for many reasons, including the potential for economic upheaval, worker hardship, and, perhaps most importantly, insight into the future of manufacturing jobs in the United States.

"If we need to go all out, we will," Fain declared at the Facebook gathering. That's right, "everything is on the table."

On Thursday, negotiations between the union and the automakers came down to the wire. On Thursday afternoon, GM presented a fresh offer that matched Ford's and increased pay by 20%.
