UASIN Gishu has recalled sacking letters for more than 100 nurses who had been hired on contract.
The nurses have been asked to return the letters to the area Public Service Board.
Kenya National Union of Nurses has however rejected the board's demand that the nurses write apology letters before they are reinstated.
"The nurses did not make any mistake to write apology letters. They have to be reinstated unconditionally and as a union we will not withdraw the case we filed in court," union secretary John Bii said yesterday.
Nurses said they will go on strike from tomorrow to protest the counties decision to sack their colleagues who had been hired on contract.
However, Governor Jackson Mandago says the nurses hired on contract have to adhere to terms and conditions issued by the county and withdraw a court case against the Uasin Gishu.
"You can not take me to court and then expect me to pay you so that you use that money against the county. No way," said Mandago who was speaking in his office on Friday.
He accused the nurses of being misled by the union not to sign evaluation forms yet all county workers must be evaluated.
"The county is not a walk-in-walk-out kiosk. If they want to be hired and paid then they have to adhere to employment requirements by the county public service board," Mandago said.
The nurses through the union filed a lawsuit against the county government to demand permanent positions.
