We describe human rights violations against migrant workers at the Thailand-Myanmar border, and evaluate differences by gender and industry. This mixed methods study pairs key informant interviews ( n = 40) with a cross-sectional quantitative survey of migrant workers from Myanmar ( n = 589) recruited via respondent-driven sampling. Key informants described significant hazards during migration, including deception, theft, and physical and sexual abuse, the latter primarily for women. Quantitative results confirmed prevalent mistreatment and abuse, with significant gender differences, most notably women's disproportionate burden of sexual abuse. Current evidence on the nature of experiences, and significant differences by gender, can position prevention and response programming.
