Agrupación de Trabajadores Latinoamericanos Sindicalistas or ATLAS was a Latin American trade union confederation in the early 1950s.
During the first presidency of General Juan Perón, "workers attaches" were stationed at Argentina's Latin American embassies encouraging the creation of Peronist trade unions.
After years of preparation, the Argentinian CGT called a conference of trade unions in Asunción, Paraguay in February 1952.
With the help of the Mexican trade union CROM a general congress was held in Mexico City which launched the new Agrupación de Trabajadores Latinoamericanos Sindicalistas.
[1] The CGT had been barred from addressing the founding conference of Confederación Interamericana de Trabajadores (forerunner of ORIT), due to their criticism of U.S. trade union policies.
