The Los Angeles streetcar strike of 1919 was the most violent revolt against the open-shop policies of the Pacific Electric Railway Company in Los Angeles. Labor organizers had fought for over a decade to increase wages, decrease work hours, and legalize unions for streetcar workers of the Los Angeles basin. After having been denied unionization rights and changes in work policies by the National War Labor Board, streetcar workers broke out in massive protest before being subdued by local armed police force.
