DETROIT (Michigan News Source) – With two tentative contracts on the table for Ford and Stellantis, the United Auto Workers union appeared to use that leverage with General Motors as it expanded its strike to a plant in Tennessee on Saturday night.

The union walked out at a GM factory in Spring Hill, Tennessee. The UAW said on social media , “Local 1853 members who work at GM Spring Hill Manufacturing have received the call and are joining the Stand Up Strike!”

GM released a response to the strike expansion, stating, “We are disappointed by the UAW’s action in light of the progress we have made. We have continued to bargain in good faith with the UAW, and our goal remains to reach an agreement as quickly as possible.”

Ford’s UAW national council will vote on Sunday whether to send a contract to members. The UAW reached a tentative deal with Stellantis just hours before the GM plant walkout.
