This article examines the contribution of the FILEF (Federazione Italiana Lavoratori Migranti e Famiglie) to the European debate on the human, social and civil rights of migrant workers during the 1970s. Through the project of an ‘International Statute of Migrant Workers’ Rights’, presented to the European Parliament in 1971, FILEF submitted a proposal for the reform of the 1968 Community Regulation on the Free Movement of Migrant Workers in Europe in order to extend to workers from non-European countries the same rights and protections accorded to those from the EEC area. The analysis is focused on the discussion around the proposal in the committees of the European Parliament as well as on the debate that developed within the transnational network of the FILEF during the international conferences organised by the Federation from the mid-1970s until the early 1980s.
