Ambulance personnel who are on strike say their dispute with the HSE is unnecessary.
500 workers who are members of the Psychiatric Nurses Association are on picket lines across the country, including outside University Hospital Kerry, for a second day today.
They want the HSE to recognise the PNA, which has a specific branch for ambulance workers.
The HSE has so far refused, claiming that engaging with another union will harm good industrial relations.
Paramedic Tony Gregg says the HSE could easily put an end to the strike.
