Like all American car plants, the production lines at Fremont seldom stopped, and when mistakes were made cars continued down the line with the expectation that they would be fixed later. By the early 1980s, the adversarial relationship had deteriorated to the point where employees drank alcohol, smoked marijuana (at the time, an illegal activity), were frequently absent (enough so that the production line couldn't be started), and even committed petty acts of sabotage such as putting "Coke bottles inside the door panels, so they'd rattle and annoy the customer." It was stated at times on Mondays and Fridays there weren't enough workers to start the line, so GM would often go to the bar across the street to hire workers to take their place. Employees at the Fremont plant were "considered the worst workforce in the automobile industry in the United States," according to a later recounting by a leader of the workers' own union, the United Auto Workers (UAW). Attempts to discipline workers were often met with grievances or even strikes, putting the plant into near-continuous chaos. By 1982, GM had had enough and closed Fremont Assembly and laid off its thousands of workers. Partially demolished (south end and water tower), the remaining plant was refurbished and was used for the more successful NUMMI (New United Motor Manufacturing, Inc.) joint-venture between GM and Toyota between 1984 and 2010 and later became the Tesla Factory in 2010.
