The United Auto Workers union is prepared to strike Fiat Chrysler Wednesday. The strike would be the first in the industry since 2007, affecting about 40,000 workers. Take a look back at the 10 biggest strikes in U.S. history.
1. Great Southwest Railroad Strike -- In March 1886, the Knights of Labor went on strike over unsafe work conditions and unfair hours and pay at the Union Pacific and Missouri Pacific railroads, affecting 200,000 workers in five states. Nonunion workers and violence and scare tactics forced an end to the strike in September that year.
