Approximately 1,350 workers represented by the International Association of Machinists and Aerospace Workers (IAM) Local 778 are increasing efforts to reach an agreement with Olin Winchester after a strike began at the Lake City Army Ammunition Plant in Independence, Missouri. The union announced on April 9 that negotiations have resumed but no resolution has been reached yet.
The ongoing labor dispute is significant because the plant is considered one of the most important facilities in the U.S. defense industrial base, manufacturing small arms ammunition such as 5.56 mm, 7.62 mm, and .50-caliber rifle rounds for the military. The facility is noted as being capable of rapidly scaling production to meet national defense needs.
Union members went on strike after rejecting what they described as a substandard contract offer from management on April 4. IAM sources say that production at the plant has slowed considerably due to the absence of its trained workforce, raising concerns about timely ammunition supply amid rising global conflicts.
Scott Brown, Directing Business Representative for IAM Local 778, said: “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. Our members are ready to get back to work, but it takes a fair agreement that reflects their value and the critical role they play.”
Sam Cicinelli, Midwest Territory General Vice President for IAM Union, 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. Olin Winchester needs to come to the table with a serious proposal that respects these workers and ensures the long-term stability of this operation.”
Brian Bryant, International President of IAM Union added: “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.”
Olin Corp., which operates Olin Winchester at Lake City Army Ammunition Plant under federal contracts since receiving over $53 million in state and local subsidies since 2001—and more than $81 million in loans or other public support—has not yet presented terms acceptable to union members.
IAM Local 778 plans a solidarity rally on Saturday April 11 while negotiations continue.
