Hundreds of employees of the Eastern Cape health department have been issued with final warnings aft.
Mandla Mandela is pleading with his cousin, Ndileka Mandela, to reconsider her decision not to vote for the governing ANC any more.
Mandla wrote an "open letter" in response to Ndileka 's statement last week that she would no longer vote for the party. The eldest granddaughter of former President Nelson Mandela said she had taken the decision in the wake of the Life Esidimeni scandal and the social grant crisis.
Ndileka, 52, said both matters could have been prevented.
In response, Mandla said Ndileka should rather try to "breathe new life to the ANC" and not turn away when "the house is on fire".
He wrote: "I read your heart-wrenching decision with empathy and understanding. I am sure this was not an easy step for you to take as the ANC has been the heartbeat of our family for many years.
"I call on you to reconsider your decision," Mandla wrote.
"What we are dissatisfied with in the ANC, it is our obligation to set right. Abandoning the ANC does not serve the people of South Africa; it only serves to weaken the ranks of those who want to restore our beloved organisation to the pride of place it deserves."
But when contacted for comment by Sowetan's sister newspaper, Daily Dispatch, Ndileka said: "Granddad once said when faced with a dilemma, people of integrity, of purpose, of public morality must always look to their conscience".
Ndileka was on Friday quoted as saying that she was highly upset by the Life Esidimeni incident and South African Social Security Agency scandal.
