Approximately 1,350 workers represented by the International Association of Machinists and Aerospace Workers (IAM) Local 778 are continuing their strike at the Lake City Army Ammunition Plant in Independence, Missouri, according to an April 9 statement from the union. The workers are calling for a fair contract and urging Olin Winchester to address concerns related to pay, high turnover, and mandatory overtime.
The ongoing strike is significant because the Lake City facility is a key part of the U.S. defense industrial base. It produces small arms ammunition critical for national security and is described as the only site capable of rapidly scaling production to meet defense demands. Disruptions at this plant could impact timely ammunition supply for U.S. forces and allied partners during a period of escalating global conflicts.
Union representatives said that negotiations with company officials have taken place recently, but no agreement has been reached yet. “The company needs to recognize the highly skilled work being done at this facility and deliver a contract that keeps up with inflation, reduces excessive mandatory overtime and addresses the high turnover that is hurting this operation,” said IAM Union Local 778 Directing Business Representative Scott Brown. He added that members are ready to return if presented with a fair deal.
Sam Cicinelli, IAM Union Midwest Territory General Vice President, said: “This facility plays a vital role in our nation’s defense, and it takes a highly trained, dedicated workforce to keep it running at full capacity.” Cicinelli called on Olin Winchester to offer “a serious proposal that respects these workers and ensures the long-term stability of this operation.” IAM Union International President Brian Bryant stated: “As global conflicts continue to escalate, the importance of this work cannot be overstated… Our members are standing up for a fair contract that reflects their skill, their sacrifice and the essential role they play in supporting our nation and its allies.”
The union also highlighted previous advocacy efforts in Congress which helped prevent federal funding cuts affecting both Olin Winchester operations and jobs in recent years. According to IAM Union sources cited in their release, economic activity generated by these workers supports nearly 50 local businesses with over $108 million contributed annually.
Looking ahead, IAM Local 778 plans to hold a solidarity rally on Saturday, April 11 as negotiations continue.
