Ambulance personnel belonging to the Psychiatric Nurses Association (PNA) have mounted another day of strike action nationally.
Speaking outside University Hospital Galway, John Dillane of the National Ambulance Service Representative Association (NASRA) said they would continue to campaign for their right to join, and be represented by the PNA as the union of their choice.
The PNA National Ambulance Branch will hold an Extraordinary General Meeting (EGM) of its members later this month in Mullingar, Co Westmeath to consider further escalation of industrial action.
Up to 2010, SIPTU represented most frontline personnel in the National Ambulance Service - but since then, the PNA says up to 500 staff have left SIPTU to join NASRA.
However, the Health Service Executive insists that recognising another union for the ambulance grades would lead to fragmentation and impair good industrial relations. It has also refused to deduct and remit union subscriptions for members.
