UAW Members at Mack Trucks Reject Tentative Agreement, Walk Out on Strike

After voting by 73% to reject a tentative agreement, nearly 4,000 UAW members at Mack Trucks in Pennsylvania, Maryland, and Florida walked out on strike at 7 a.m. on Monday, October 9.  

“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,” said UAW President Shawn Fain. “The members have the final say, and it's their solidarity and organization that will win a fair contract at Mack.” 

After weeks of failing to address core economic issues, the company reached a tentative agreement with just minutes to spare before the initial deadline on October 1. On Sunday, October 8, Mack Trucks UAW members voted down the deal. UAW leadership then issued a strike notice to the company, citing “many topics [that] remain at issue, including: wage increases, cost of living allowances (COLA), job security, wage progression, skilled trades, shift premium, holiday schedules, work schedules, health and safety, seniority, pension, 401(k), healthcare and prescription drug coverage, and overtime.” 

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

The Mack Trucks strikers bring the total number of striking UAW members to over 30,000 workers across 22 states.
