The red umbrella is an important symbol for sex worker rights and is used for events that are held on December 17. The red umbrella symbol was first used by sex workers in Venice, Italy, in 2001. Slovenian artist Tadej Pogacar collaborated with sex workers to create the "Prostitute Pavilion" and CODE: RED art installation for the 49th Venice Biennale of Art. Sex workers also held a street demonstration, the Red Umbrellas March, to protest inhumane work conditions and human rights abuses.
