This book is about the illicit crime of Forced Labour, from a global perspective. Forced labour can be imposed to adults and children, by State authorities, by private enterprises or by individuals. It is observed in all types of economic activity, such as domestic work, construction, agriculture, manufacturing, sexual exploitation, forced begging, etc. and in every country. "traditional practices of forced labour, such as vestiges of slavery or slave-like practices, and various forms of debt bondage, as well as new forms of forced labour that have emerged in recent decades, such as human trafficking." also called "modern-slavery" to shed light on working and living conditions contrary to human dignity. Forced labour is different from sub-standard or exploitative working conditions. Various indicators can be used to ascertain when a situation amounts to forced labour, such as restrictions on workers' freedom of movement, withholding of wages or identity documents, physical or sexual violence, threats and intimidation or fraudulent debt from which workers cannot escape. In addition to being a serious violation of fundamental human rights and labour rights, the exaction of forced labour is a criminal offence.
