So you haven't been balloted to strike then - which is what Mum2Be said. 
This is from the NASUWT:
98 per cent of teachers were deeply angry about the Coalition Government's proposals to change teachers' and other public service workers' pensions. The overwhelming majority were prepared to take strike action should the Coalition Government proceed with its proposals.
Chris Keates, General Secretary of the NASUWT, said:
"This is a staggeringly high response, which in itself illustrates the intense anger the Coalition's proposals have generated. "This survey is a clear warning to Coalition ministers.
"On the basis of this, I have written to the Chief Secretary to the Treasury, Danny Alexander, lodging a formal dispute over pensions.
"I have warned him that, should the Coalition Government either fail to take seriously the concerns of teachers or fail to use the negotiations with the TUC genuinely and seriously to seek an agreed outcome, then the overwhelming support for industrial action among NASUWT members will be translated into reality with inevitable widespread disruption.
