A pro-union sign is seen in front of the United Auto Workers Union building in Oshkosh, Wis., on July 15, 2022. The UAW shop is located across the street from the Oshkosh Defense facility. Oshkosh Defense announced in 2021 that it would not build up to 165,000 postal trucks using its existing Oshkosh assembly lines but shift production to a new $155 million plant in Spartanburg, S.C.
