5. Harlem Hospital
In 1962, Harlem Hospital workers, who were largely black and Puerto Rican, went on strike for better wages and benefits. Malcolm X headlined a coalition of activists and politicians who supported the workers. The strike was successful, and the union, Local 1199, went on to organize many of New York City’s hospitals, and today is one of the most powerful unions in New York. Harlem Hospital is also where Martin Luther King Jr. was taken after he was stabbed in New York City.
