Libertarian Syndicalist Union

The union was founded on 5 October 2003, after a congress that accepted its founding declaration.^[1] Initially, it participated in the International Libertarian Solidarity (ILS) while it was ongoing, while maintaining links with the International Workers' Association (IWA).^[1] The union is independent of any political party and is organized around local (or professional) assemblies based on the principle of direct democracy.^[2] The union proclaims its solidarity with anti-capitalist and anti-fascist struggles.^[2]

During the Greek economic crisis, the union was part of the Greek anarchist organisations that were critical of the idea of cooperativising the economy.^[3] Additionally, it assisted in the reception of migrants in Greece.^[4]

In 2016, it left the IWA along with the Confederación Nacional del Trabajo (CNT), the Argentine Regional Workers' Federation (FORA), and the Italian Syndicalist Union (USI).^[5] In 2018, these organisations founded the International Confederation of Labour (ICL), where they reunited.^[5][6] The union has become one of the most active and numerous anarcho-communist and anarcho-syndicalist organisations in Greece.^[7]

In 2023, the organisation published a translation of Breaking the Chains: A History of Anarchism by Lucien van der Walt.^[8]
