The main transport workers union (Satawu) has announced plans for a national truck driver strike after failed negotiations attempts with truck employers. Satawu said truckers are seeking and increase of 12% for 2013 and 2014. The transport union refused to say how much the employers' association is offering, but local radio station Talk 702 put the figure at 8%.

South Africa's central reserve bank has forecast inflation will hold steady at around 5% percent through 2014. There was no immediate comment from the The Road Freight Association of transport employers. A strike could disrupt fuel supply chains and retail businesses in the country . The fear of violence is a concern as to what has happened in the mining sector of strikes.
