Teaching union chiefs have failed to secure support for strike action after not enough staff turned out to vote.
Nine out of 10 members of the NASUWT in England and Wales voted for strikes over pay.
However, the turnout was 42 per cent, below the 50 per cent legal threshold, the teachers’ union announced.
Various teachers’ union chiefs had threatened to bring chaos to schools after saying “no concrete progress” was made during last-ditch talks with Gillian Keegan, the Education Secretary, last week.
Ballots of the NASUWT, National Education Union and the NAHT all closed this week.
The dispute centres on this year’s pay deal, which is worth 5 per cent to most teachers and leaders.
In response to the disappointing result on Thursday afternoon, the NASUWT general secretary Patrick Roach lashed out at the Government’s “anti-trade union legislation” requiring 50 per cent turnout rates.
Despite the low turnout, he said it was “clear that our members are sending a strong message” to ministers.
“Whilst the Government’s anti-trade union legislation prevents members in state-funded schools and colleges from taking industrial action, we remain in formal disputes with ministers and employers and will be continuing to take forward our campaigning for a Better Deal for Teachers,” he said.
“The readiness of our members to support industrial action demonstrates the anger of the profession and the need for governments in England and Wales to engage in meaningful negotiations to address the deep concerns of our members.
“Our campaign to fight for the real-terms pay awards that teachers and headteachers deserve continues.”
