A United Auto Workers union member holds a sign outside Stellantis Sterling Heights Assembly Plant, to mark the beginning of contract negotiations in Sterling Heights, Michigan, U.S. July 12, 2023.
About 73% of workers - covering 4,000 workers in Pennsylvania, Florida and Maryland - voted against the deal, the UAW said.
After Mack workers voted down the deal, the UAW sent a strike notice to the company saying "many topics" remain at issue, including wage increases, cost-of-living allowance, job security and wage progression.
"We clearly demonstrated our commitment to good faith bargaining by arriving at a tentative agreement that was endorsed by both the International UAW and the UAW Mack Truck Council," Roy said.
"UAW members and workers across the economy are mobilizing to demand their fair share," the UAW said in a letter to Mack.
