Earlier this week, a majority of United Auto Workers union members voted in favor of a new contract with Mack Trucks, bringing an end to a 39-day strike at the company’s three plants. The approval of this five-year deal followed the rejection of a previous contract, which had been tentatively agreed upon between the union negotiators and the company. The earlier proposal, which offered a 19% wage increase, was turned down by the union members who deemed it insufficient. The specific details of the newly ratified contract have not been disclosed to the public.

“The new agreement guarantees significant wage growth and delivers excellent benefits for our employees and their families,” said Mack President Stephen Roy. “At the same time, it will safeguard our competitiveness and allow us to continue making the necessary investments in our people, plants, and products.”

The recently approved agreement applies to approximately 3,900 workers at Mack facilities situated in Pennsylvania, Maryland, and Florida. These employees are anticipated to resume their duties starting this Monday.

This development in the United Auto Workers’ negotiations with Mack coincides with the union’s ongoing efforts to conclude contracts with major automakers such as Ford, General Motors, and Stellantis.
