Employees of the centre for emergency medical help in Sofia on January 8 went on protest and relay hunger strike.
They accuse the director of depriving them of extra pay because of denunciations.
A meeting was held at the health ministry late last week and an inquiry has been assigned.
The protest was organised by “Zashtita” (Protection) trade union.
