Most Northern Ireland teachers are to go on strike for the first time in five years following the half-term break in a dispute over pay.
The half-day strike action by the three main teaching unions here - the UTU, INTO and NASUWT - will take place next month.
Teachers will withdraw their labour from schools for 12 hours on Tuesday, February 21, before returning to their normal afternoon duties over the failure to offer "a fair and decent" pay award.
