Only eight of the 41 member states of the Council of Europe have signed its Convention on the Rights of Migrant Workers, 1977. Those states are France, Italy, the Netherlands, Norway, Portugal, Spain, Sweden and Turkey.
The substance of this convention was incorporated into the Council of Europe's Revised European Social Charter, 1996, which Ireland signed and ratified on 4 November 2000.
Articles 18 and 19 of the Revised European Social Charter – the Right to Engage in a Gainful Occupation in the Territory of Other Parties (Member States of the Council of Europe) and the Right of Migrant Workers and Their Families to Protection and Assistance – are the main articles dedicated to the issue of migrant workers.
Ireland signed and ratified the revised charter because it is a new human rights treaty which updates the rights protected in the original European Social Charter of 1961 in areas such as employment, social protection, non-discrimination, education and health. It also incorporates the Convention of the Rights of Migrant Workers, 1977.
