Unions threaten fresh strike over public sector pensions Strike ballots held last year are still active, so no further votes would be needed although unions will have to give seven days' notice of any more stoppages. Some unions are currently consulting their members on whether to accept the Government's deal as the best that can be achieved through negotiation, but a number of large unions are said to be "standing firm." Chris Keates, general secretary of the NASUWT teachers union, said: "The heads of agreement document signed up to by four unions before Christmas is set to wreak massive injustice on the overwhelming majority of teachers. The NASUWT will be seeking to mitigate the worst aspects of the agreement by demanding that teachers do not bear an unfair burden of unjustified increased contributions, whilst employers see the level of their contributions reduced. The NASUWT will be insisting that the Government obeys the law by providing a detailed Equality Impact Statement and by exercising its duty to advance equality. The scandal is that none of these changes are about making the pension scheme viable, affordable or sustainable. These changes are part of the Government's privatisation scheme to make education more attractive to predatory business interests. It is understood that motions from local branches supporting fresh strikes have been sent to the NUT.
