Teachers could be the latest group to threaten industrial action in response to possible further cuts on pay and service.
The INTO will ballot their members on strike action this evening.
The union is asking teachers to support its call for up to three days industrial action.
In March of this year, primary teachers voted for industrial action. However, strike action was deferred to facilitate further talks with government.
The INTO said "no meaningful engagement" had taken place in the intervening months.
