Health workers, under the aegis of Joint Health Sector Unions (JOHESU), have begun their planned strike.
The action took effect at 12 a.m on Monday, following the alleged inability of the Federal Government to meet their demands.
JOHESU urged its members to withdraw their services across the country to key into the industrial action.
The union said it took the decision at its expanded National Executive Council (NEC), which took place on Sunday.
