Firefighters are preparing to merge with the Psychiatric Nurses Association (PNA) in a bid to create a breakaway trade union and revolutionise frontline services.


The move comes following revelations by the Sunday Tribune that disillusioned members of the Dublin Fire Brigade were attempting to break ranks with Siptu – the main union – over a perceived lack of representation.


While the move has been galvanised by disquiet at the recent Croke Park deal, sources close to the merger have ruled out any prospect of immediate strike action.


Application forms for the new firefighters union, which were discreetly circulated in recent months, have now been completed by between 1,500 and 1,800 members around the country, a figure representing up to 45% of the overall service.


The newly established Irish Fire and Emergency Services Association (IFESA), as it is currently titled, is understood to be concerned over Siptu's representation and is keen to bring about change independently.


"The reason it's getting a lot of uptake is pretty simple," said a source close to the IFESA.


"We are paying 15% into our pension and now we are paying a pension levy. Some of the young lads are coming in and saying, 'I can't afford my house.'"


Aside from representing members on pay issues, a new union would focus on the formation of a national fire and ambulance body, replacing the fractured service currently in place.


Sources have indicated that paramedics may sign up alongside firefighters and psychiatric nurses. The move is expected to attract opposition from Siptu.
