This national social justice network is dedicated to promoting the human rights of sex workers and their communities. The network consists of 27 local chapters that vary in size and include both sex workers and allied activists. SWOP-USA focuses much of its attention on ending stigma and violence against sex workers through education and advocacy. The network is active at local levels through its SWOP chapters, as well as at the national level. Through a dedicated website and related communications, SWOP actively encourages and supports sex workers in the United States and worldwide to honour December 17 as the International Day to End Violence Against Sex Workers.
