A rolling day of action is due to be held on January 31 by National Association of Schoolmasters/Union of Women Teachers (NASUWT) members in schools across Londonderry and Strabane, Mid Ulster, and Fermanagh and Omagh.
It follows a walk out in Belfast and Newtownabbey on November 30.
Teachers have rejected an offer that would have delivered a 1% rise this year, with rates for 2015/16 remaining frozen.
Education minister Peter Weir has claimed a bigger increase could only be afforded by making redundancies. NASUWT has 12,000 members in Northern Ireland across primary and secondary schools.
