Educational psychologists working at most councils across England have voted in favour of strike action over pay.
The Association of Educational Psychologists revealed today it had achieved a 70 per cent turnout in its national ballot.
Eighty-six per cent voted in favour of industrial action, comfortably surpassing the thresholds set by government.
Ballots for strike met the thresholds in 130 out of 157 council areas, while a further six voted for action short of a strike.
