Members of the Congress of South African Trade Union (Cosatu's) will hold pickets at the offices of the National Treasury in protest against changes to retirement fund laws.
Cosatu claims that National Treasury lied to Parliament about the consultation process over the new pension laws.
EWN reporter Govan Whittles said that Cosatu members will also picket outside of National Development and Labour Council (Nedlac) offices on Friday.
Listen to the full conversation from The Midday Report with Stephen Grootes:
They want the new tax laws to be taken back to Nedlac and consulted with from scratch and believe it should be repealed immediately.— Govan Whittles, EWN reporter
They say they don't plan on abandoning the campaign. The national strike against the tax reform will commence on 1 March 2016, when the law comes into effect.— Govan Whittles, EWN reporter
