Secondary school teachers will hold a one-day strike before the General Election.
The action comes after members of the Teachers' Union of Ireland voted 89% in favour of industrial action over issues of pay and security of employment for young teachers.
Members will engage in a one-day strike on a date yet to be decided.
They say the stoppage will go ahead unless their demand for meaningful talks is met.
Lecturers in Institutes of Technology will also strike on February 3 over serious concerns in their sector.
Their union, the TUI, has said key concerns include chronic underfunding of the sector, a rise in student numbers when the amount of lecturers has dropped and the precarious nature of many lecturers' employment status.
