60 ward administrators and communication officers in Kiambu County were sent on compulsory leave on Wednesday pending their performance evaluations.
The communication officers were asked to take a 30-day leave from August 22.
In a letter signed by chief officer Marie Mugo, the team was told to hand over the working equipment to their supervisors and obtain clearance for the same.
They were also asked to surrender vehicles and any other county material in their possession.
They will be on leave until October 3 after which they will be told whether or not they will retain their jobs.
"The county has not specified the reason we are proceeding on compulsory leave," an employee was quoted by The Star.
New Kiambu governor Ferdinand Waititu is set to clean up the county offices and plans to remove workers who were hired without due procedure.
Nonetheless, Public Service Commission chair Margaret Kobia has warned incoming county administrations against sacking workers.
She says this will subject counties to numerous legal battles that may see them make settlements using county funds.
Kobia said the sackings, which many of the new county bosses are considering, will also destabilise the human resource.
In Machakos, Governor Alfred Mutua sent 437 workers home in what he termed as a "radical surgery" meant to improve service delivery to the people.
In Kajiado, employees are jittery amid claims Governor Joseph ole Lenku is planning a clean-up of the workforce.
