Backstory and Context
General Motors started to produce trucks from the Janesville assembly plant in 1923, after producing tractors for the first four years of their existence. During World War II, the plant manufactured artillery to support the Allied War efforts. It wasn’t long after the war that the plant started producing cars again. At it’s peak in 1977, the Janesville assembly plant employed 7,100 workers which was roughly 14% of Janesville’s population. Due to declining profits and the need for cutbacks, General Motors decided to shut down the Janesville assembly plant in 2008 and officially closed in 2009. The plant has produced over 16 million automobiles in its 89-year existence.
