Fresh school closures loom this autumn as a major teachers' union voted overwhelmingly for walkouts over pay.
In a bitter dispute over pay and working conditions, a staggering 88.5% of eligible members of the NASUWT voted to back strike action.
The union, which has 300,000 members across the UK, failed to meet legal turnout rules earlier this year. But anger at the Government's measly pay offer has pushed its members to back walkouts on a turnout of 51.9%.
