Union of Cinema Production Workers

Union of Cinema Production Workers (Sindicato de Trabajadores de la Producción Cinematográfica) was an autonomous (non-"charro"-led) Mexican trade union. It was formed in 1944 after splitting off from the CTM-affiliated Union of Cinema Industry Workers (Sindicato de Trabajadores de la Industria Cinematográfica, (STIC)). Mario Moreno "Cantinflas" served as its first secretary general.
