The Homeless Workers Movement is a social movement in Brazil. It originated from the Movimento dos Trabalhadores Rurais Sem Terra. Although the MTST can trace its first urban activism efforts to the occupation of Campinas in São Paulo during the 1997 National People's March, this intervention was organized within the Landless Rural Worker's Rural Movement structure. The first proper occupation as a new sociopolitical actor, distinct from the MST, took place in Guarulhos in 2002. It was named after Anita Garibaldi, considered to be a radical social reformer during her lifetime.
Struggle for housing
Through direct confrontation and negotiation with the local, state or the federal government, MTST attempts to reduce Brazil's housing deficit by staging squatters' occupations in unoccupied plots marked as Special Social Interest Zones that owe property taxes. Determining an exact number on the housing shortage in Brazil is a difficult task to achieve, but several estimates have been provided. In 2019, The Guardian reported 7.7 million while Habitat for Humanity places the number between 6–8 million. By resisting attempts by local governments to evict the poor and negotiating for their conversion into low-income housing, MTST has challenged the neoliberal model. In fact, at the national level, previous governments have undermined affordable housing projects, including the emblematic Minha Casa, Minha Vida, but have failed at doing so due to MTST interventions.According to MTST, there are over 5 million housing units available in abandoned buildings in Brazil. São Paulo, for example, was short of housing units in the 500,000 – 700,000 range as of 2017. As noted before, MTST originally emerged as a faction within MST and focuses on urban reform. Although fully autonomous, the organization has a strategic alliance with MST and also works closely with other Brazilian urban social movements such as the União Nacional de Moradia Popular and the Centro dos Movimentos Populares.
