The National Education Union, NEU says Teachers in England will strike over pay again on two dates in July.
It said the National strikes are scheduled for 5 and 7 July and many schools are likely to fully or partially close.
The NEU has called for negotiations with the government to start again and says strike action is a last resort.
The Department for Education said further strike action would cause real damage to pupil learning.
Education Secretary, Gillian Keegan has previously said strike action was extremely disappointing.
Keegan said there have already been five national and three regional strike days since February by members of the NEU, which is UK’s largest education union.
NEU’s joint general secretaries, Mary Bousted and Kevin Courtney said the education secretary had turned her back on teachers in England.
They called on the Education secretary, Keegan, to get round the negotiation table, saying their calls have time and again fallen on stony ground.
The Department for Education described it as a fair and reasonable offer, saying that schools would receive an extra £2.3bn over the next two years.
