About 13,000 U.S. auto workers stopped making vehicles and headed for the picket lines Friday after their leaders couldn’t bridge a giant gap between union demands in contract talks and what Detroit’s three automakers are willing to pay.

About 13,000 U.S. auto workers stopped making vehicles and went on strike Friday after their leaders couldn’t bridge a giant gap between union demands in contract talks and what Detroit’s three automakers are willing to pay.

Members of the United Auto Workers union began picketing at a General Motors assembly plant in Wentzville, Missouri, a Ford factory in Wayne, Michigan, near Detroit, and a Stellantis Jeep plant in Toledo, Ohio.

It was the first time in the union’s 88-year history that it walked out on all three companies simultaneously as four-year contracts with the companies expired at 11:59 p.m. Thursday.
