The spectre of a large strike among ambulance workers has loomed after union members voted 82% in favour of industrial action.

Unison’s 1,500 A&E members at Yorkshire Ambulance Service have launched a dispute amid claims management were not keeping to agreements made with the union.

The union says the ambulance service has backtracked on policies over meal breaks, promises that end-of-shift overtime would be reduced, the use of private ambulances and a five year workforce plan which includes a pay rise for middle grade medics.

A spokesman said: “Unison A&E members have given the branch committee a clear and resounding mandate that they are willing to take industrial action due to the Trust not adhering to recently agreed policies and procedures.”

Union chiefs are meeting on Friday to discuss what action to take.

Ian Brandwood, Executive Director of People and Engagement at Yorkshire Ambulance Service NHS Trust, said: “We are disappointed by the result and do not feel that industrial action will help us respond to the challenges we face. We will continue to work with Unison representatives to try and develop a response to staff concerns and avoid any industrial action.

“The Trust is already making changes to address some of the concerns raised and our focus remains on the well-being of our staff whilst continuing to provide high levels of patient care.

“Further meetings with Unison have been arranged and we will also be meeting jointly with ACAS next week in an attempt to resolve the current dispute.”
