This offer was rejected by PSA members who say they were not consulted.On Monday, the group marched to Sassa's regional offices and handed over a memorandum listing their demands.

She said: "We work under risky conditions. They are lying to the media and saying everything is well at Sassa. Nothing is well. We have raised the issue of safe working conditions. People are sick. Imagine serving a person with multidrug-resistant TB."Everything has increased. Petrol is high. We can't provide for our families. We are paid peanuts," said Mbhele.PSA member Zodwa Nene said: "They back paid us on Friday. That was the agreement with their unions. PSA was not consulted. We stand by the percent we demanded. Sassa must respect us."Perfect Zulu, acting provincial manager of the PSA, said the union tabled its demands in February.Also read: Sassa urges patience, assures beneficiaries grants will be paid despite difficulties"Ever since we started negotiations with Sassa, there has been no agreement. If Sassa does not meet the demands, the strike will continue. Employees will down tools until their grievances are attended to.""What is important is that the employees were paid. I'm not sure how much was given. Money was paid and they are refusing to take that offer."
