The first legal steps taken to end the occurrence of child labour was enacted more than fifty years ago. In 1966, the nation adopted the UN General Assembly of the International Covenant on Economic, Social and Cultural Rights. This act legally limited the minimum age for when children could start work at the age of 14. But 23 years later in 1989 the Convention on the Rights of Children was adopted and helped to reduce the exploitation of children and demanded safe working environments. They all worked towards the goal of ending the most problematic forms of child labour.
