A restavek (or restavec) is a child in Haiti who is sent by his or her parents to work for a host household as a domestic servant because the parents lack the resources required to support the child. The term comes from the French language rester avec, "to stay with". Parents unable to care for children may send them to live with wealthier (or less poor) families; often their own relatives or friends. Often the children are from rural areas and relatives who host restaveks live in more urban ones. The expectation is that the children will receive food and housing (and sometimes an education) in exchange for doing housework. However, many restaveks live in poverty, may not receive proper education, and are at grave risk for physical, emotional, and sexual abuse. The restavek system is tolerated in Haitian culture, but not considered to be preferable. The practice meets formal international definitions of modern day slavery and child trafficking, and affects an estimated 300,000 Haitian children.
