Book VIII Print 30: Inaugural session of the 10th Congress of the Confederación de Trabajadores CubanosYale University. Department of Manuscripts and Archives1958 November 18engspaInaugural session of the 10th Congress of the Confederación de Trabajadores Cubanos [CTC], Cuba's largest umbrella syndicate of labor unions, held November 18, 1959, in Havana. The congress was considered the first "liberated" meeting of the CTC because Batista's political allies, such as Eusebio Mujal, who had formerly controlled its elections and decisions through corruption and intimidation, were no longer present. Although the congress was supposed to begin in the early afternoon, it did not start until 10:30 PM when Fidel Castro finally arrived to give the opening address. In the background of the stage, there are two signs posted, which read "Trabjadores: De tu peso depende la liberación económica de la CTC" and another one simply saying "4%." These signs reference two government-initiated campaigns for worker donations to the industrialization of the country and the purchasing of arms for its defense against U.S.-based incursions that had garnered the support of CTC leaders aligned with Fidel Castro's 26th of July Movement. The highest ranking of these leaders, David Salvador (with beard), is seen sitting at the front table on stage, one man down from the right of Che Guevara (with beret). At the far end of the front table is President Osvaldo Dorticós (in glasses). Others in attendance include Augusto Martínez Sánchez, the Minister of Labor. See also Print 37.
