Over a hundred Eskom shopstewards from the National Union of Mineworkers (NUM) have taken a unanimous decision that members employed at the parastatal should go on strike action on May 26, a move that could impact the World Cup which begins in June.
The strike - which was suspended last year pending negotiations- would begin on May 26 and a massive march would take place to Megawatt Park, Eskom's headquarters.
"Workers demand that Eskom should address all their outstanding issues from last year's negotiation cycle," the NUM said in a statement.
This included a housing allowance.
"Amid several marches and memoranda delivered to Eskom, the parastatal is yet to respond to the demands."
Eskom was not able to comment immediately.
