Between the establishment of DENOSA on 5 December 1996 and 1998, DENOSA was not affiliated to any trade union federation. In 1998, however, and after intense internal discussions within DENOSA, it was resolved that DENOSA be affiliated to COSATU as a means to advance the socio-economic interests of its members in the workplace.
A reflection and assessment of this decisions are done every four years during national congresses, whether to remain affiliated to COSATU or not.
