No forced labour may be used, including debt bondage, slavery, prison labour and hard labour. Human trafficking activities are also forbidden. Suppliers are obliged to monitor all third-party companies supporting them in recruitment or employee placement to ensure that persons seeking employment at their facilities are not compelled to do so by force, deceit, intimidation, coercion or as a punishment for the adoption or expression of political views. (ILO Conventions 29, 105, 182)
