GMB, the union for health workers, has responded to Labour’s call for an urgent NHS rescue plan.
Analysis by the party shows patients are routinely waiting more than 18 weeks for treatment.
Rachel Harrison, GMB National Officer, said:
"After ten years of pay cuts and underfunding, morale among NHS staff is at rock bottom.
"The health service faces a crippling recruitment and retention crisis, leading to 75,000 vacancies and huge waits for routine surgery.
"GMB is calling for a restorative 15% increase to make up for a decade of slashed pay under the Conservatives.
"We have no hesitation in recommending members vote to reject the 3% and no hesitation in supporting members if they want to take action."
