The Office to Monitor and Combat Trafficking in Persons, an agency of the United States Department of State, says that “’modern slavery’, ‘trafficking in persons’, and ‘human trafficking’ have been used as umbrella terms for the act of recruiting, harboring, transporting, providing or obtaining a person for compelled labor or commercial sex acts through the use of force, fraud, or coercion”.
Besides these, a number of different terms are used in the US federal Victims of Trafficking and Violence Protection Act of 2000 and the United Nations Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children, including “involuntary servitude”, “slavery” or “practices similar to slavery”, “debt bondage”, and “forced labor”.
