The International Labor Organization (ILO) elaborated a series of indicators in order to identify cases of severe labor exploitation. These indicators include the threat or use of force, the limitation of freedom and movement, the imposition of a debt on the worker, withholding the salary and confiscating documents.
The main work sectors involved in this phenomenon are agriculture, manufacturing, domestic assistance, and the construction sector.
Exploited workers are often unconscious of their situation, because in many cases their life conditions have improved compared to their previous life in the country of origin. Many times they also belong to minority communities or social groups that have historically suffered severe forms of discrimination.
