About UAW Local 578

On February 16, 1938, eighteen members of Oshkosh Truck Corporation were officially approved by the International Auto Workers to obtain a charter. The very charter that created Local 578 to serve the newly formed membership of Oshkosh Truck has not changed. Over 70 plus years, the vigilant Union honors those who stood united in the beginning with their dedication to the best possible workplace for the membership of Oshkosh Truck and will remain strong for the future.

UAW Local 578 is located in Oshkosh, Wisconsin, and is a part of UAW Region 4.


The International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW) is one of the largest and most diverse unions in North America, with members in virtually every sector of the economy.

UAW-represented workplaces range from multinational corporations, small manufacturers and state and local governments to colleges and universities, hospitals and private non-profit organizations.

The UAW has more than 390,000 active members and more than 600,000 retired members in the United States, Canada and Puerto Rico.

* The first employer-paid health insurance plan for industrial workers
