On 24th October, thousands of ambulance workers can vote on whether to take strike action.
The GMB union has announced that a ballot will start on 24th October for ambulance staff at 11 trusts across England and Wales.
15,000+ members could vote on taking industrial action in the current pay dispute, with the GMB having said that any strike that takes place could take place before Christmas.
The Department of Health and Social Care (DHSC) has asked unions to "carefully consider" any effect that this may have on 1,000’s of patients.
A spokesperson from the GMB has said that ambulance staff were angered at the government's stated 4% pay rise, which they are of the view that it is a "massive real terms pay cut".
Staff from trusts all over the Wales and England trusts will take part in the ballot, which closes on 29 November.
"Pay has been systematically slashed for more than 10 years and we now face the worst cost of living crush in a generation. Meanwhile vacancies are at record highs and we have the worst A&E delays ever - and it's not even the winter flu season yet” said Rachel Harrison - GMB national officer.
"Members feel like they are unable to deliver safe standards of patient care".
A spokesperson from the DHSC previously said industrial action was a "matter for unions".
They also added that the government valued the "hard work of NHS staff" and had given more than "one million NHS workers a pay rise of at least £1,400 this year".
