Juno Mac is a sex worker and activist with the Sex Worker Open University (SWOU), a sex worker-led collective with branches in London, Leeds and Glasgow. SWOU is focussed on advocacy, campaigning, cultural events and community support for sex workers.

Through their organizing, SWOU activists support each other through stigma and isolation, demand better working conditions by fighting criminalization and provide public education around issues relating to sex worker rights. Mac's activist work with SWOU has included delivering workshops in universities, political lobbying and campaigning, consulting with human rights organisations (including Amnesty International), appearances on radio and TV, and taking part in public panel discussions at festivals and conferences.

Mac has also curated an exhibition of sex worker art, contributed to magazines and a live storytelling night, facilitated skill-sharing and support spaces for fellow sex workers, and helped to organise SWOU's Open Conference of The Advancement of Sex Worker Rights 2015.
