Dublin firefighters have voted in favour of strike action.
SIPTU members voted overwhelmingly for the action in a row over attempts by senior management in Dublin City Council to break up DFB's Emergency Medical Service by outsourcing its ambulance call and dispatch function.
They voted 93% in favour of the action.
SIPTU Organiser John King said: "What the senior management of Dublin City Council is attempting by seeking to outsource the ambulance call and dispatch function of the DFB Emergency Medical Service would compromise the safety of our members, who deliver this critical lifesaving service, as well as expose the public to increased risk.”
