Prostitution law
However, sex worker activists and organizations distinguish between human trafficking and legitimate sex work, and assert the importance of recognizing that trafficking is not synonymous with sex work. The Sex Workers Alliance Ireland organization explains: "victims of human trafficking may be forced to work in industries such as agriculture, domestic service as well as the sex industry. It is critical to distinguish human trafficking, which is a violation of human rights, from voluntary migration." The Open Society Foundations organization states: "sex work is done by consenting adults, where the act of selling or buying sexual services is not a violation of human rights. In fact, sex workers are natural allies in the fight against trafficking. The UNAIDS Guidance Note on HIV and Sex Work recognizes that sex worker organizations are best positioned to refer people who are victims of trafficking to appropriate services."

Anti-trafficking agendas from different groups can also be in conflict. In the movement for sex workers rights, sex workers establish unions and organizations, which seek to eliminate trafficking. However, law enforcement also seek to eliminate trafficking and to prosecute trafficking, and their work may infringe on sex workers' rights and agency. For example, the sex workers union DMSC (Durbar Mahila Samanwaya Committee) in Kolkata, India, has "self-regulatory boards" (SRBs) that patrol the red light districts and assist girls who are underage or trafficked. The union opposes police intervention and interferes with police efforts to bring minor girls out of brothels, on the grounds that police action might have an adverse impact on non-trafficked sex workers, especially because police officers in many places are corrupt and violent in their operations. Critics argue that since sex trafficking is an economic and violent crime, it calls for law enforcement to intervene and prevent violence against victims.
