Teachers in a Co Limerick secondary school have voted in favour of taking industrial action as a result of grievances related to the management and operation of the school.
Teachers at Coláiste Chiaráin in Croom were balloted on the issue late last week.
It has not yet been decided what form the action will take.
The staff are members of the Teacher's Union of Ireland.
The TUI said the union would continue to seek resolution of the matter through the established industrial relations mechanisms.
It said it would not be making any further comment on the matter.
Coláiste Chiaráin has grown dramatically in recent years, largely as a result of large numbers of students from Limerick city travelling out by bus to the rural school.
The school is run by Limerick and Clare Education and Training Board.
