Thousands of ambulance workers across the country are walking out in a dispute over pay today after unions announced strike action with paramedics and 999 call handlers.
Up to 15,000 Unison ambulance workers are striking on Monday for the third time in five weeks, and will be joined by 5,000 of their NHS colleagues at two hospital trusts in Liverpool.
Almost 1,000 ambulance workers across the West Midlands in the GMB union will also strike, including paramedics and emergency care assistants.
Ten further days of strike action have been announced by ambulance workers at Unite for February and March.

Yorkshire Ambulance Service
Ambulance crews working for five services in England represented by Unison will also go out on strike. These include:
The North West
The North East
The South West
What calls will paramedics respond to?
It is expected that ambulance workers will respond to the most life-threatening conditions classed as category 1, including heart attacks or sepsis.
Some ambulance trusts have also agreed exemptions with unions within category 2, which covers conditions such as suspected strokes. However, most conditions within categories 2 to 4 will not covered.
Sir Stephen Powis, the national medical director for NHS England, said on Wednesday: "We've been working very closely with the unions to ensure that emergency services for life-threatening conditions are maintained, and that will include stroke and heart attacks.
"There are increased clinicians in call centres to ensure that the right response goes out to the right incident."
He said strokes fall into the higher end of category 2 cases, so clinicians will determine what response is needed, and he advised people to dial 999 "as usual" if they have a life-threatening condition.
What to do if you need emergency help during a strike
The Department of Health and Social Care have said the advice remains for people to call 999 in an emergency.
A spokesperson said: "Health leaders are also concerned that the prospect of strike action may affect how people decide to engage with the NHS, but the advice remains that if it is an emergency, it is vital they should still call 999."
Therefore, people should continue to call 999 if they believe they need immediate response to a life-threatening condition.
