Durham, Newcastle and Manchester are the only Russell Group universities that have policies in place to support their students who work in the sex industry. There is an estimate that there are 214,200 student sex workers. That does sound high to me, but not all those student sex workers would be student escorts.
It is a pity that other Universities do not provide advice to those who are sex workers. Advice on STIs, the law, and organisations they can turn to for help.
Outside the Russell Group unis, Leicester University released the Student Sex Work Toolkit. The safety resource includes details for staff on how to communicate with students about their sex work and signposting of further sources of information. They also outline a guide on the legalities of sex work and tips for students to keep themselves safe.
None of this is encouragement to students to work as escorts, but rather to help those who already work in the sex industry to be safe.
