The British Medical Association (BMA) has warned the government is refusing to cooperate in talks over cuts to the NHS pension scheme.
It said the government has "no desire to talk" to health unions and is insisting on implementing a 6% hike in GP pension contributions, Pulse reports.
Such an increase in contributions will cost GPs up to £125,000 each over their careers, BMA research found.
Dr Andrew Dearden, chair of the BMA pensions committee, said the government will only allow discussion on how to introduce the contribution hike, not the increase itself.
Meanwhile, Dr Hamish Meldrum, chairman of council at the BMA, said the contribution hike is "a tax on public sector workers" and the NHS pension scheme is already affordable.
"The NHS pension is currently delivering a massive surplus to the Treasury," he said.
"It underwent major reform only three years ago, which saw doctors' contributions increase significantly."
The BMA in Scotland has also rejected the proposed changes to the NHS pension scheme.
Last week, the chairman of the BMA in Scotland Dr Brian Keighley called for the Scottish government to undertake a national consultation on the proposed changes.
