Teachers have rejected a Welsh government pay offer and are set to go on strike next month.
The National Education Union postponed Tuesday's strike but will now walk out on 2 March following a meeting between officials.
Ministers had offered an extra 1.5% pay rise, plus 1.5% as a one-off payment.
Teachers in the NEU and the National Association of Headteachers (NAHT) previously rejected this year's pay rise of 5%.
Had they accepted the new offer, that would have meant a 6.5% pay rise with an additional one-off 1.5% this year.
Two further strikes are planned for 15 and 16 March.
