Johannesburg - Political parties have asked President Cyril Ramaphosa to urgently act on Eskom and stabilise the organisation following the resignation of its chief executive, Phakamani Hadebe.
He quit on Friday citing health reasons and the unimaginable demands of the job which he said was taking a toll on him and his family.
Eskom chairperson Jabu Mabuza said Hadebe would leave at the end of July.
The power utility has to find a new chief executive as it goes through the unbundling process.
Cosatu has opposed any job losses at Eskom after Ramaphosa announced the entity would be split into three entities.
