Both the National Union of Teachers (NUT) and University and College Union have agreed to take action on March 28.
The decision came after a national survey of the NUT showed that 95 per cent of members disagreed with the government’s attacks on pensions, and 73 per cent backed further strikes.
Christine Blower, General Secretary of the National Union of Teachers, the biggest teachers’ union, said: “The Government is well aware that teachers do not accept the changes that they propose to make to our pensions.
“The vast majority of teaching unions have not signed up to the latest pension proposals which still mean that teachers will have to pay much more, work much longer and get much less in retirement.
“The NUT believes it is essential that the teaching profession stands united on this issue. Working and taking action together in June and November 2011 brought some concessions from Government, but they do not go far enough. We have no evidence whatsoever that teachers’ pensions are unaffordable.
“We will be writing to the other teaching unions to look at the ways we can work together to defend the profession and our pensions, and will be discussing how to take the campaign forward at the NUT Annual Conference this Easter.”
Other unions for NHS and civil service workers also plan to take new industrial action over the deal, which would force members to work for longer and pay more.
A spokeswoman for the Department of Education said: “This is very disappointing. The deal on the table is as good as it gets and talks are not going to be reopened.”
