More than 100 nurses in Vanuatu are calling for the removal of the health minister, Serge Vohor.
The nurses, who are members of the Vanuatu Nurses Association, have sent a petition to the prime minister, Moana Carcasses.
They are unhappy at Mr Vohor's revamping of the health sector which has led to the suspension of three senior doctors.
The changes have also caused division within the Nurses Association, with some backing Mr Vohor.
Government officials say they are aware of the petition and the issue is now with the Public Service Commission.
