In contemporary post-professional times, social work expert knowledge and authority have been challenged by the new managerialism, proletarianisation and technocratisation. This chapter responds to the potential of broadening the scope of social work to incorporate para- and non-professional lay practitioners from within local communities in social service delivery. Post-professionalisation is experienced, in this way, as an opportunity to renew social work professionalism, and not necessarily as a threat. This chapter provides a case study that examines community health work in peri-urban Maputo City, Mozambique, illustrating that the widespread adoption of Western state-directed social work and its modernist ideas of professionalism, are ill suited for many countries of the Global South. The community health worker engagement model proposed here is applicable to Nordic countries, but to try to transfer the model, the prevailing ideas of social work professionalism need to be decolonised.
