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
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.
