Members of the National Education Union (NEU) have backed strike action over pay and funding in an indicative ballot.
The vote only just reached the turnout threshold that would need to be met in a formal ballot to authorise walkouts.
The indicative ballot was announced in January amid fears among unions that the government will only raise pay by between 1 and 2 per cent from September.
Today, the NEU announced that among voting members in England, 90.3 per cent said they supported strike action. The turnout was 50.3 per cent.
