Schools minister Nick Gibb has been heckled by teachers while giving a speech at the Association of Teachers and Lecturers' (ATL's) annual conference.
The politician told teachers that the government could not "ignore the realities of the cost pressures" of the pension scheme, the BBC reports.
"This is why long-term reform of public service schemes is needed - and why teachers and other public-service scheme members are being asked to pay a higher pension contribution from April 2012," Mr Gibb commented.
However, he added that public service pensions "should remain a gold standard".
ATL general secretary Dr Mary Bousted said: "If ATL is so angry, where is the government going to go on its pension reforms. We're middle England, if you alienate us where do you go?"
Speaking earlier this week, Lesley Ward said the government is attempting a "wholesale dismantling of state education".
He argued that the coalition's education reform plans are beginning to spiral out of control.
