Social work in Namibia is practised in a context marked by extreme levels of poverty and socio-economic inequalities. These interrelated challenges remain deeply entrenched despite several development efforts at national, regional and international level. As a social justice and human rights-oriented profession that has a global footprint, social work pledges to promote socio-economic equalities in view of realising a just and equal world. Such a structural emphasis on tackling socio-economic inequalities is a radical departure from the micro-level centred approaches that have historically dominated social work practice in Namibia. In this qualitative study, we explored 10 purposively selected Namibian social workers’ perceptions of socio-economic inequalities through semi-structured one-on-one interviews. The findings indicate that social workers are intricately aware of the socio-economic inequalities that characterise the Namibian society, but that their focus on micro practice restricts them to deal with the structural causes that retain socio-economic inequalities. Adopting a developmental approach as policy framework for social welfare and social work will enable social workers to bridge micro and macro practice, challenge oppressive structures and contribute to social transformation and a just and sustainable world.
