As president, Díaz Ordaz was known for his authoritarian manner of rule over his cabinet and the country in general. His strictness was evident in his handling of a number of protests during his term, in which railroad workers, teachers, and doctors were fired for taking industrial action. A first demonstration of this new authoritarianism was given when he used force to end a strike by medics. Medics of the Institute for Social Security and Services for State Workers, especially residents and interns, had organized a strike to demand better working conditions and an increased salary.
