The Frontlines Initiative is a joint project of four national public sector unions - the Canadian Union of Postal Workers (CUPW), the Public Service Alliance of Canada (PSAC), the Canadian Union of Public Employees (CUPE) and the National Union of Public and General Employees (NUPGE) - which joins forces with sister unions in Colombia to fight against the privatization of public services and to strengthen each other’s struggles to defend human and labour rights. The delegation in Colombia received an important briefing on the Trade in Services Agreement (TISA), a proposed international trade treaty that, if ratified, will put public services in Colombia, Canada and 48 other countries at extreme risk.
