Cape Town - Cosatu has vowed to take Eskom on over its plan for a further electricity tariff hike on top of the 12.69% for direct customers that will kick in on April 1.
Cosatu's national spokesperson Patrick Craven told Fin24 on Monday that if its submission to energy regulator Nersa to reject Eskom's application for a further tariff increase fails, the trade union federation would consider rolling mass action.
