The GMB union is expected to announce further ambulance worker strike dates this Wednesday, Sky News understands.
Members held a meeting that lasted more than two hours on Monday following a long-running dispute over pay, jobs and conditions.
They will announce the outcome of today’s ambulance committee meeting at 1pm on Wednesday, Sky News can reveal.
Up to six more dates are being discussed after talks with Health Secretary Steve Barclay last week broke down.
Lib Whitfield, from GMB, said: “There’s a huge amount of anger from our members working in the ambulance service and from the representatives that Steve Barclay is not taking this seriously.
“Our members are saving lives day in, day out, and that is actually at risk because of the cuts they’ve made to the service. Our members will not back down in this fight and they need Steve Barclay to actually take them seriously.”
GMB members at the meeting were said to be “very angry”, especially over the anti-strikes bill being debated in parliament today, which will mean key industries will have to legally ensure minimum service levels during walk-outs.
Last Wednesday, about 25,000 ambulance workers across England and Wales went on strike.
Staggered walkouts by paramedics, call handlers, drivers and technicians from the Unison and GMB unions took place over a 24-hour period.
NHS England figures released last week show average ambulance response times in England last month were the longest on record.
In December, the average response time for ambulances dealing with the most urgent incidents – defined as calls from people with life-threatening illnesses or injuries – was 10 minutes and 57 seconds. The target is seven minutes.
