This study by Standup Movement Sri Lanka examines the status and experiences of female sex workers (FSWs) in Sri Lanka, with comparative insights from India and Thailand. The report highlights how legal frameworks, social attitudes, and economic structures perpetuate their marginalization. Despite their significant contributions to the informal economy and family livelihoods, FSWs face criminalization, stigma, health risks, exclusion from welfare systems, and lack of recognition as workers, which reinforces cycles of poverty, insecurity, and social exclusion. The research seeks to identify pathways for integrating FSWs into the informal labour sector through legal reforms, public health initiatives, and community support, aiming to improve their access to services, protect their rights, and ensure dignity and economic security. It contributes to broader policy and human rights discussions by offering evidence-based recommendations for a more just and equitable approach to sex work in Sri Lanka.
