BOISA was first created in 2012 and was officially registered in 2014. Their constitutional mandate is to advocate, represent and promote the rights and wellbeing of all informal economy workers. The organization officially joined StreetNet as an affiliate in 2019. They often work with the Botswana Federation of Trade Unions (BFTU), but are not formally affiliated.
