Kenya Medical Practitioners and Dentist Union officials have moved to court seeking the extension of a court order requiring them to be jailed.
According to KMPDU officials, they need more time to allow time for more talks.
Labour Relations court judge Hellen Wasilwa had given KMPDU bosses up to Thursday to call off the strike or go to prison for one month.
The request comes at a time when talks between the government and the officials failed.
The doctors have rejected government's 40 per cent salary increase.
