On the day the National Union of Teachers begins balloting members on strike action, Graham Lane, chair of the LGA's education committee, said: 'If they withdraw their labour, we will deduct money from their pay for as long as they refuse to work.
'It is the duty of employers to deduct pay from people who break their contracts, and we will have no hesitation in doing so.
'If people take industrial action of any sort, they will have to accept the consequences. We could not allow people to break their contracts without doing something about it.'
Ministers are currently engaging in talks with the three main teaching unions and the two headteachers' organisations in a bid to stall industrial action before it begins.
