The International Labor Organization (ILO), the United Nations body which regulates the world of work, launched the World Day Against Child Labor in 2002 in order to bring attention and join efforts to fight against child labor. This day brings together governments, local authorities, and civil society and international, workers and employers organizations to point out the child labor problem and define the guidelines to help child laborers. According to ILO's data, hundreds of millions of girls and boys throughout the world are involved in work that deprives them from receiving adequate education, health, leisure and basic freedoms, violating this way their rights. Of these children, more than half are exposed to the worst forms of child labor. These worst forms of child labor include work in hazardous environments, slavery, or other forms of forced labor, illicit activities such as drug trafficking and prostitution, as well as involvement in armed conflict.
