Homelessness is an increasing social challenge both locally and globally. Social problems associated with street homelessness and services provided to homeless people by social workers are well documented in South Africa. Little is known though concerning the collaborative role of social workers and homeless people in addressing street homelessness. This study explored the role of social workers in promoting social justice through a collaborative purpose amongst the homeless people in addressing street homelessness. A qualitative, explorative, descriptive, and contextual study was undertaken with 14 homeless participants aged 21 to 63, and eight social work participants aged 25 to 38. This study was informed by an amalgamation of two theories, indicating the collaboration theory and the structural theory. Data were collected through semi-structured interviews, analysed by following Tesch’s eight steps (Creswell, 2009:186). The data was collected and verified, employing the Lincoln and Guba’s model of trustworthiness. The ethical considerations adhered throughout this study are informed consent, confidentiality and anonymity, management of information and debriefing. The major findings identified first, poverty and unemployment as major homelessness causes. Second, deprived, or non-existing family support, family or marital breakdown, substance use, migration of individuals from rural or foreign countries to city centres, as major contributing factors towards homelessness. Third, homeless people are more vulnerable to personal harm than the housed population. Fourth, the society and derogatory labels, such as crazy, nyaopes, and criminals are often used to describe these individuals. Finally, homelessness places homeless people at substantial risk of elevated mental health conditions. Implications for social work and recommendations for future research are presented. / Social Work / M.A. (Social Work)
