Kenya's government has sacked some 25,000 striking nurses for failing to return to work.
Spokesman Alfred Mutua has appealed to "all qualified health professionals who are unemployed or retired" to report to public hospitals for jobs today.
The public health workers, who are mainly nurses, have been on strike for four days demanding better pay, allowances and working conditions.
The unions have dismissed the move as a negotiating tactic.
Last week employees at Kenya's state broadcaster also downed tools.
The government threatened them with the sack and advertised their posts in the newspapers.
However the dispute was revolved and no jobs were lost.
