OSHKOSH, WI (WTAQ)-Oshkosh Corporation says the company and the bargaining committee for UAW Local 578 have reached a contract agreement. The vote is scheduled for Sunday at noon. The current contract between the company and the union expires in 2016, but the company is seeking an extension through 2021. Oshkosh Corporation is in the running for a roughly $13 billion contract with the Army and Marine Corps to build the replacement vehicle for the Humvee. A contract extension would give the company a predictable cost structure.
