New York CNN  — 

The United Auto Workers union is expanding its strike against GM and Stellantis but raised hopes that progress is being made in talks by saying it would not have workers at Ford join the strike at this time.

UAW President Shawn Fain made the announcement on Friday morning. “At noon Eastern today, all parts distributions centers at General Motors and Stellantis will be on strike,” he said. “We will shut down parts distribution until those two companies come to their senses and come to the table with a serious offer.”

But Fain said that there has been significant improvement in offers from Ford and that is the reason the strike will not be expanded there.

“We do want to recognize that Ford is serious about reaching a deal,” he said.

As of 10:30 am ET, Stellantis (STLA) is up 0.98%; Ford (F) is up 3.57%; and GM (GM) is up 0.7%.
