More than 2,000 trade unionists have been killed and 138 have been victims of enforced disappearance in Colombia over the last two decades. In more than 90 per cent of cases, those responsible have not been brought to justice. Amnesty International considers that the human rights situation facing trade unionists remains serious. The Colombian authorities have taken some steps to improve their safety. However, more decisive action must be taken to ensure that freedom of association rights are respected, in practice as well as in law.
