Teachers at a high school in Kompong Cham went on strike to protest the corruption of the school's principal.
Mr. Rong Chhun, the president of independent teachers said he had written a letter to the ministry of education asking it to intervene.
Mr. Rong said the ministry official promised to return to settle the allegations but the official never returned.
The teachers accused the principal of stealing money from the school and for using school property for private gain.
VOA stringer could not contact the principal for her comments. The official at the ministry of education told VOA stringer that the minister of education was busy and could not answer the phone
