Migrant sex work
Because of their illegal and vulnerable economic status, some migrant sex workers may find themselves in situations where coercion and forced sex work may be present. Under international legal definitions of human trafficking, forced and coercive forms of sex work are considered to be instances of involuntary sex trafficking. However, many scholars caution against categorizing sex workers as either completely voluntary or completely involuntary. They often argue that sex work, like other forms of labor, can span a spectrum between the two extremes, with most circumstances falling in the middle through various labor rights violations. Nevertheless, the vulnerability of migrant sex workers can make them susceptible to exploitative or coercive labor practices that can resemble or be human trafficking.
Human trafficking
Although human trafficking can occur at local or domestic levels, it has international implications, as recognized by the United Nations in the Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children (also referred to as the "Trafficking Protocol" or the "Palermo Protocol"), an international agreement under the UN Convention against Transnational Organized Crime (CTOC) which entered into force on 25 December 2003. The protocol is one of three which supplement the CTOC. The "Trafficking Protocol" is the first global, legally binding instrument on trafficking in over half a century, and the only one with an agreed-upon definition of trafficking in persons. One of its purposes is to facilitate international cooperation in investigating and prosecuting such trafficking. Another is to protect and assist human trafficking's victims with full respect for their rights as established in the Universal Declaration of Human Rights. The "Trafficking Protocol", which had 117 signatories and as of November, 2018 173 parties, defines human trafficking as:
In 2014, the International Labour Organization estimated $150 billion in annual profit is generated from forced labour alone.
