All three of Unite’s sectors involved in the dispute have voted to reject.
That covers workers in health, local government and government departments such as the Ministry of Defence.
Members of Unite’s executive have also forced a meeting to be called, set to take place this Thursday.
NUT and NASUWT, the two biggest teaching unions by far, have both refused to sign the “heads of agreement”.
So has EIS in Scotland, Ucac in Wales and Into in Northern Ireland.
But no teaching union has yet named a day for further strikes.
The NUT executive met last week and unanimously voted to keep up the pensions fight.
A proposal calling on the union to canvass support for strikes in February and March was lost by 26 votes to 13.
NUT executive member Nick Grant said, “We have no option but to continue the fight with more strikes as soon as possible.”
The ATL has signed up and the NAHT is surveying its members.
The main civil service union, PCS, rejects the deal. But Prospect and the FDA have signed up.
UCU general secretary Sally Hunt has called for a ballot on the deal instead of rejecting it.
Members of the union’s executive are campaigning to overturn this decision.
