UAW workers reject Mack Trucks contract offer and vote to go on strike

• The tentative agreement also included a 10% general wage increase in year one for all employees and a guarantee of no increases in health insurance premiums through the term of the contract, according to a Mack Trucks statement emailed on Sunday night.

Zoom out: Some 25,000 UAW members have been on strike against General Motors, Ford and Stellantis since Sept. 15, though the union reported "significant progress" in contract talks with the Detroit Three automakers on Friday.

What they're saying: "I'm inspired to see UAW members at Mack 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.

The other side: Mack president Stephen Roy said in an emailed statement he was "surprised and disappointed" with the strike announcement following the tentative agreement that was "endorsed" by both the International UAW and the UAW Mack Truck Council.

• "We are committed to the collective bargaining process, and remain confident that we will be able to arrive at an agreement that delivers competitive wages and benefits for our employees and their families, while safeguarding our future as a competitive company and stable long-term employer," Roy added.

• "We look forward to returning to negotiations as soon as possible."
