Unitarians and revolutionaries. The trade unionism of the MC and the LCR in CCOO

ABSTRACT This article aims to analyse the trade union trajectory of the Movimiento Comunista (MC) and of the Liga Comunista Revolucionaria (LCR) within the Comisiones Obreras (CCOO), the main workers’ organisation during the Transition. Both, the MC and the RCL actively participated in its construction, seeing the CCOO as the materialisation of the workers’ United Front (FU). Both organisations maintained relations within the CCOO for many years. These relations went through moments of collaboration and sympathy, moments of distancing and later moments of stable alliance against the Partido Comunista de España (PCE) inside of CCOO. From this alliance came the Izquierda Sindical (IS), a trade union platform which for many years brought together trade unionists from the two organisations until its absolute dissolution at the end of 1991. The history of their trade union intervention can help to better understand the history of these organisations, which are still in the process of being re-discovered by the academy.
