Workers at a Mansfield factory walk out as part of UAW strike

Workers at a Stellantis facility in Mansfield walked out on the job as part of the expanding United Auto Workers strike, the labor group’s leader said Friday.

Nationwide, another 5,600 additional workers joined the strike on top of the 13,000 of the 146,000 members that began the strike one week ago.

"This expansion will also take our fight nationwide. We will be everywhere from California to Massachusetts, from Oregon to Florida," said UAW President Shawn Fain during a liv broadcast on Friday. "Across the country, people are going to know that the UAW is ready to stand up for our communities, and ready to stand up against corporate greed."

The expansion targeted General Motors and Stellantis distribution centers. Ford was spared additional strikes because the company has met some of the union’s demands during negotiations over the past week, Fain said.

“We’ve made some real progress at Ford,” Fain said during an online presentation to union members. “We still have serious issues to work through, but we do want to recognize that Ford is showing that they are serious about reaching a deal.”

“At GM and Stellantis, it’s a different story,” he said. Those companies, he said, have rejected the union’s proposals for cost-of-living increases, profit sharing and job security.

The union is pointing to the companies’ huge recent profits as it seeks wage increases of 36% over four years. The companies have offered a little over half that amount. The UAW has other demands, including a 32-hour work week for 40 hours of pay and a restoration of traditional pension plans for newer workers.

The companies say they can’t afford to meet the union’s demands because they need to invest profits in a costly transition from gas-powered cars to electric vehicles.

The UAW’s contract with the automakers expired at midnight on Sept. 14, and workers walked out of a Ford assembly plant near Detroit, a GM factory in Wentzville, Missouri, and a Jeep plant run by Stellantis in Toledo, Ohio.

Fain said earlier this week he would call on workers at more plants to strike unless there was significant progress in contract negotiations with the carmakers. Bargaining continued Thursday, although neither side reported any breakthroughs, and they remained far apart on wage increases.

The companies have laid off a thousands of workers, saying some factories are running short on parts because of the strike.

Still, the impact is not yet being felt on car lots around the country – it will probably take a few weeks before the strike causes a significant shortage of new vehicles, according to analysts. Prices could rise even sooner, however, if the prospect of a prolonged strike triggers panic buying.

The union is seeking pay raises of 36% over four years, an end to lower pay scales for new workers, and most boldly, a 32-hour work week for 40 hours of pay. The car companies say they can’t afford the union’s demands despite huge profits because they need to invest in the transformation to electric vehicles.
