Drop-in centers are often the only places where sex workers can access health care, legal counseling, and other direct services. They also provide a safe space for sex workers to congregate, document abuses, and mobilize for advocacy. The role of drop-in centers is critical given the extreme and rampant violations of sex workers’ human rights in most places around the world. Common violations include physical and sexual violence, unsafe and unjust working conditions, extortion, and lack of access to justice, health care, social welfare, and other services.
