Members of United Auto Workers walked off the job Monday morning at Mack Truck facilities in three states, after rejecting a tentative contract agreement with the company.

According to a statement from UAW, 73% of the 4,000 workers voted to reject the tentative agreement with Greensboro, N.C.-based Mack, which was reached shortly ahead of an Oct. 1 deadline. The Associated Press reported the contract would have included a 19% pay raise.

“I’m inspired to see UAW members at Mack Trucks holding out for a better deal, and ready to stand up and walk off the job to win it,” UAW president Shawn Fain said in a statement Monday. “The members have the final say, and it’s their solidarity and organization that will win a fair contract at Mack.”

Fain said in a letter to Mack company officials that there were several topics that remained at issue, including wage increases, cost of living allowances, job security, work schedules, health and safety, pensions, and overtime.

UAW Locals 171, 677, 1247, 2301, and 2420 in UAW Region 8 and Region 9 represent workers at Mack Trucks locations in Macungie and Middletown, Pennsylvania; Hagerstown and Baltimore, Maryland; and Jacksonville, Florida, the union said.

Mack Trucks president Stephen Roy said in a statement, the company was “surprised and disappointed” by the strike “which we feel is unnecessary.” The tentative agreement  was endorsed by both the International UAW and the UAW Mack Truck Council, Roy added.

With Monday’s strike, there are now more than 30,000 UAW workers on strike in 22 states, the union said. That includes workers at several locations of the Big Three Detroit automakers, Ford, General Motors and Stellantis, who went on strike Sept. 15.

President Biden visited one of the UAW’s picket lines in Michigan on Sept. 26, believed to be a first for a sitting president. Biden has touted his stance as the “most pro-union president,” in recent campaign events.
