Today in Labor History March 14, 1954: Salt of the Earth premiered. The film depicted the 1951 strike of Mexican-American workers at the Empire Zinc mine, in New Mexico. The film was one of the first to portray a feminist political point of view, particularly through Actress Rosaura Revueltas’s role as Esperanza Quintero. When the Company uses the new Taft-Hartley Act (which also bans General Strikes) to impose an injunction preventing the men from picketing, their wives go walk the picket line in their places. LGBTQ and labor activist Will Geer also played in the film. Writer Michael Wilson, director Herbert Biberman and producer Paul Jarrico had all been blacklisted for their alleged communist ties. Only 13 of the 13,000 theaters in the U.S. showed the film.
