The Papua New Guinea Teacher's Association is calling for the Enga provincial government to do more to protect teachers.
The threat of illegal high powered guns in the province is keeping schools shut and causing a teacher shortage.
Children and teachers are reported to be frightened of going to school due to ongoing tribal fighting that involves illegal weapons.
The acting general secretary for the Teacher's Association, Gordon Kavop, says the government needs to take law and order more seriously.
"The security involved in making sure our teachers do their job properly is basically our main concern. The other stakeholders like the government, is not very serious about protecting and ensuring teachers are safe and protected in their place of work."
