The International Trade Union Confederation (ITUC) is calling on governments to sign and ratify the Treaty on the Prohibition of Nuclear Weapons (TPNW), on the eve of a special signing ceremony for the Treaty at the UN in New York this week. The Treaty was adopted by the UN in July 2017, with a vote of 122-1, and requires ratification by 50 countries for it to come into force. So far 70 countries have signed it and 26 have completed ratification.
