This day is celebrated on 2nd June not only in Europe but around the world. International Sex Workers' Day is observed on 2nd June because on 2 June 1975 approximately 100 sex workers occupied at Sant-Nizier Church in Lyon, France, to express anger about their exploitative living conditions and work culture. The Church was brutally raided by the police forces on 10 June. This action becomes a national movement and so, is now celebrated in Europe and worldwide.
