Title: Mack Trucks Workers Strike After Rejecting Tentative Agreement


Nearly 4,000 members of the United Auto Workers union (UAW) are on strike at heavy truck manufacturer Mack Trucks after voting down a tentative agreement reached a week ago. The rejection of the proposed deal, which included improved wages, benefits, and bonuses, was supported by 73% of the workers. The strike at Mack Trucks comes as the UAW continues its strikes against three major car manufacturers, marking the first time in the union’s history that it has struck all three simultaneously.

Union’s Demands and Mack Trucks’ Response

The UAW’s bargaining goals at Mack Trucks align with its demands in negotiations with General Motors, Ford, and Stellantis—the Big Three automakers. These demands include better wages, healthcare, and pension benefits. The rejected contract offered an immediate 10% pay raise, additional pay increases over the five-year contract period, a signing bonus, improved vacation and holidays, and no increase in insurance premiums paid by members.

Stephen Roy, president of Mack Trucks, expressed surprise and disappointment at the union’s decision to strike. He emphasized that the tentative agreement had been endorsed by both the International UAW and the UAW Mack Truck Council, demonstrating the company’s commitment to good-faith bargaining.

Background on Mack Trucks and Ownership

Mack Trucks, a major US manufacturer of heavy-duty and medium-duty trucks, delivered 27,000 trucks in 2022 and 16,000 in the first half of 2023. The company is owned by Sweden’s Volvo Group, which is separate from the Volvo car brand owned by China’s Geely.

Strike Impact and Presidential Support

The ongoing work stoppage at Mack Trucks has joined the UAW’s strikes against other car manufacturers, resulting in over 25,000 union members across the nation participating in strikes. President Joe Biden showed his support for the striking workers by becoming the first sitting president to visit a picket line, demonstrating his solidarity with their cause.

Increasing Struggles for Labor Agreements

In recent years, rank-and-file union members have increasingly voted down tentative labor agreements reached by their union leadership, marking a shift in labor dynamics. A similar trend was observed with FedEx pilots, who voted against a proposed contract earlier this year. However, their inability to immediately strike, unlike workers at Mack Trucks, highlighted differences in labor laws.

Escalating Strikes in a Strong Labor Market

With a strong labor market, unions have been emboldened to demand better pay, benefits, and work conditions for their members. As a result, the number of strikes involving 100 or more strikers lasting a week or more has significantly increased. According to Cornell University School of Industrial and Labor Relations, there have been 56 such strikes in the first nine months of this year, a 65% increase compared to the same period last year.


The strike by nearly 4,000 UAW members at Mack Trucks highlights the union’s determination to secure a more favorable deal for workers. As negotiations continue, the union’s demands for improved wages, benefits, and working conditions not only align with those presented to the Big Three automakers but also reflect a larger trend of increasing labor strikes in the US. The coming weeks will determine the outcome of these labor disputes and potentially shape the future of worker-employer relations across various industries.
