Child trafficking can be likened to modern-day slavery. Child victims of trafficking are recruited, transported, transferred, harbored or received for the purpose of exploitation. Children are exploited and forced to work in brick kilns and sweatshops, on construction sites, in houses as domestic slaves, on the streets as child beggars, in wars as child soldiers, on farms for agriculture, in traveling sales crews, in the tourist industry in restaurants and hotels, in the commercial sex industry in brothels, strip clubs, and escort and massage services. Some of these conditions are easy to see—but most are hidden. That's why putting a stop to child slavery is critical to UNICEF's work.
