When the ICFI split in 1972, the League for a Workers Vanguard changed its name to the "Workers League" and became an official affiliate of an ICFI dominated by Gerry Healy's Socialist Labout League. The Leagues activities involved general recruitment, the running of classes in Marxism, the selling of, first, The Workers' Press and, later, News Line- both published in England - and attempting interventions in industrial disputes'. In the mid-seventies, the League ran a Right to Work Campaign which involved a number of demonstrations in Dublin, one of which culminated in a 'mass' meeting in the Mansion House. Jack O'Connor, who would later become General President of SIPTU in 2003, and President of ICTU in 2009, was an activist and organiser with the League for much of the 1970s. In the early 1970s, the League's General Secretary was Donal O'Sullivan. For a while, the League published Marxist Journal a general magazine that dealt with political and theoretical issues, which was edited by Paul McGuirk. The League became moribund sometime around 1978.
