Dozens of NHS trusts will be affected by strike action in December as 100,000 nurses with the Royal College of Nursing (RCN) walk out in a dispute over pay and conditions, Sky News reports.

Previously, RCN announced that its members had voted for the first time ever to take part in national industrial action amid the worsening cost of living crisis.

The strikes will take place in half of the NHS boards in England where a legal mandate was achieved, all but one in Wales and across Northern Ireland.

The Scottish Government has made a separate pay offer to the RCN and its members.

Pat Cullen, RCN general secretary, and chief executive said: "Ministers have declined my offer of formal pay negotiations and instead chosen strike action.

"It has left us with no choice but to announce where our members will be going on strike in December.

"Nursing is standing up for the profession and their patients. We've had enough of being taken for granted and being unable to provide the care patients deserve.

"Ministers still have the power and the means to stop this by opening negotiations that address our dispute."

The Union said that despite a pay award of £1,400, nurses are still 20% worse off in real terms due to inflation which has exceeded 10%.
