The largest teachers' trade union in Northern Ireland has called a programme of rolling strike action to begin in November.
The NASUWT, said the action was over pay, workload and job cuts. Union officials said, in comparison to those in England who received a 1% pay increase, teachers in Northern Ireland were offered no pay rise for the current year.
Thousands of teachers are expected to take part with hundreds of schools affected.
General Secretary Chris Keates said: "The continuing failure of employers and the Department of Education to recognise and address the serious concerns of teachers over pay, workload and job loss have caused deep anger and frustration across the teaching profession.
“The final straw, adding insult to injury, is that after months of so-called negotiations, the employers have belatedly put zero per cent on the table for teachers for 2015-16.
“Teachers’ pay in Northern Ireland is now not only failing to keep pace with trends in the graduate labour market, it is also failing to keep up with teachers across the UK, who have at least had the one per cent funded by the Treasury.
“It is disgraceful that the employers and the Department of Education, rather than paying teachers, are simply banking the one per cent from the Treasury."
Chris added: "The NASUWT is putting employers on notice that unless they come forward with a pay award for 2015-16, and unless the Department of Education agrees to genuine engagement to seek to resolve the NASUWT’s trade dispute, they will be responsible for forcing the dedicated and committed teachers of Northern Ireland to demonstrate their anger and frustration through strike action."
The Department of Education has been asked for a comment.
