Thousands of ambulance workers across five services in England will strike on February 10 in the long-running dispute over pay and staffing, Unison has announced.
The walkout involves ambulance workers in the South West, including Wiltshire.
Other areas affected by the walkout include workers in London, Yorkshire, North East and North West.
Strikes will now be happening across the NHS every day next week apart from Wednesday.
Unison urged the Government to stop “pretending the strikes will simply go away” and act decisively to end the dispute by improving pay.
The union warned that unless the Government has a “major rethink” over NHS pay, and gets involved in “actual talks” with unions, it will announce strike dates running into March.
During the last strike action affecting local ambulances, we were urged to use 999 appropriately and to call only if it is a life-threatening or life-altering emergency.
On days where there is strike action, patients should continue to call 999 if there is a medical or mental health emergency [when someone is seriously ill or injured and their life is at risk]. Ambulances will be able to respond in these situations, but this may only be where there is the most immediate risk to life.
