United Sisterhood Alliance is an alliance of four social groups in Cambodia. It evolved from an organization established in 1999 called the Womyn’s Agenda for Change (WAC). They work as a solidarity organization dedicated to address the needs of the people (in particular, women and marginalized groups) and to realize socio-economic development and justice in Cambodia. They pursue change in the lives of women, and society more broadly, by supporting the empowerment of women workers towards realization of their rights.
