Boeing defense workers ratify new contract to end 3-month strike in the Midwest

“We’re proud of what our members have fought for together and are ready to get back to building the world’s most advanced military aircraft," the International Association of Machinists and Aerospace Workers said in a statement.

With their new contract in hand, the machinists are set to return to work Sunday at manufacturing plants in the Missouri cities of St. Louis and St. Charles, as well as in Mascoutah, Illinois. The workers build fighter jets, weapons systems and the U.S. Navy’s first carrier-based unmanned aircraft at those facilities.

Boeing said in a statement that it looks forward to "bringing our full team back together.”

While the strike was smaller than last year's walkout by 33,000 Boeing workers who build commercial jetliners, it still threatened to slow the aerospace company’s efforts to regain its financial footing. Boeing’s Defense, Space & Security division makes up more than a third of its revenue.

Union leaders said talks broke down over pay and retirement benefits, while Boeing argued workers' demands went beyond the Midwest's cost of living. The breakdown in negotiations prompted the Congressional Labor Caucus to send a letter to Boeing CEO Kelly Ortberg, urging the company to return to the bargaining table.

“Boeing Defense workers produce planes and other defense equipment that the United States government and our men and women in uniform rely upon,” the letter said. “These workers are essential to the success of your company, and they deserve a fair contract that reflects their hard work and sacrifices.”

Tensions rose long before the strike, with the workers rejecting a proposed 20% raise over the contract's term and $5,000 ratification bonuses. Boeing responded with an offer that kept the same pay increases but dropped a scheduling rule that limited overtime opportunities. Workers turned that down as well and went on strike the next morning, later rejecting two other company offers.

Amid those failed votes, the union drafted its own four-year contract, which members quickly ratified. And in a move that flipped the script on traditional bargaining practices, the union sent the pre-approved contract to Boeing for its consideration. The company rebuffed the union's terms.

Last year's strike, meanwhile, shut down Boeing’s factories in Washington state for more than seven weeks at a bleak time for the company. Boeing was under several federal investigations last year after a door plug blew off a 737 Max plane during an Alaska Airlines flight, an incident that renewed safety concerns surrounding that particular plane.

Two 737 Max jetliners crashed off the coast of Indonesia and in Ethiopia less than five months apart in 2018 and 2019, killing 346 people.
