By 1946, "Trabajo" had a circulation of 7,500, which made it one of the most widely read newspapers in the country. Publication of "Trabajo" had ended by the time of the outbreak of 1948 Civil War. Whilst the Costa Rican communist were unable to maintain publication of "Trabajo", the communist-controlled trade union organ "Combate" (1943–1953) continued to appear. Later the Popular Vanguard Party founded "Adelante" as a successor to "Trabajo".
