Cleveland's Conservative PCC Steve Turner says nursing walk-outs will hit police forces.
Unison, the largest health union, is recommending its members vote in favour of walking out,In England and Wales, NHS staff, including nurses, are being given an average pay award of 4.75% more, with extra for the lowest paid, while in Scotland, 5% has been given. In Northern Ireland, nurses are yet to receive a pay award.
Mr Turner told the BBC's Politics North programme: "Strikes like this are criminal [because of] the pressure they put on other services. "From a policing perspective, if there isn't an ambulance or [people] can't get hold of a healthcare professional while [nurses] are striking, they're going to pick up the phone and ring a police officer.
"What I'm saying is you're putting people's lives at risk and you're putting other people under pressure by taking this action."with inflation running at 10.1%Responding to Mr Turner's comments, Liz Blackshaw, the TUC regional secretary for the North, said: "We're not looking at people who are making these decisions lightly, but we are looking at services on their knees.
"If you look at average waiting times for ambulances, if you look at patient waiting times, if you look at how many people are now going to private practices rather than NHS services, we're in an unsustainable position."
