Chukwudubem Ifeajuna, a nurse in the south of England, loves his job, but next month will walk out for two days as part of British nurses' biggest ever strike action, which he says is necessary for staff and patient welfare alike.

The industrial action on Dec. 15 and Dec. 20 is unprecedented in the British nursing union's 106-year history, and comes as the state-run National Health Service (NHS) braces for one of its toughest winters ever.

Ifeajuna has seen members of his team leave to work in supermarkets, where there is less stress and better pay, while he has had to cut back on spending.

"I have a few staff who are using food banks at the moment. I've had to cut down on a lot of things with the kids which I can't afford to provide for them because of the high cost of living. So it's really really tough, for everyone, not just myself," he told Reuters.

"We are striking because we deserve to be paid better. We haven't had decent pay for over a decade now."

Strike action is also impacting Britain's rail, postal and education sectors as workers struggle with soaring prices.

Patricia Marquis, director of the Royal College of Nursing (RCN) union in England, said the government must listen.

"This is not something that nurses do at the drop of a hat," she told Reuters.

'Most vicious cycles'

The RCN says experienced nurses like Ifeajuna are 20% worse off in real terms than they were in 2010 after a string of below-inflation pay awards, and are seeking a pay-rise of 5% above RPI (retail price index) inflation.

That would amount to a payrise of 19.2%, based on October's inflation data. The government says the RCN demands would cost 10 billion pounds ($12.14 billion) a year and are unaffordable.

But the RCN's Marquis said that without higher pay, staff would continue to leave the profession, increasing the pressure on those who remain and ultimately damaging patient care.

Billy Palmer, at the Nuffield Trust health think-tank, told Reuters that those who were considering leaving "often cite issues around not having enough staff to do a good job", but their departure further exacerbates the staffing problem.

"It's the most vicious of cycles," he said.

Ifeajuna says he has also sometimes considered quitting.

"But each time I've had the chance, I sort of had to pause for a minute and say 'I can't leave my patients. I can't leave my colleagues to suffer alone'," he said.
