Textile workers strike (1934)

St. Louis unemployed protest, 1934
Wikipedia - "The textile workers' strike of 1934 was the largest strike in the labor history of the United States at the time, involving 400,000 textile workers from New England, the Mid-Atlantic states and the U.S. Southern states, lasting twenty-two days. The strike's ultimate failure and the trade union's defeat left the Southeastern United States an unorganized and anti-union region for the next 50 years."
