Workers who answer 999 emergency calls have given notice of a 12 hour strike on the day before the general election - Thursday 25th of February.
The CWU, which represents the workers, says to protect the service, the work stoppage will take place only at the Navan 999 centre between 8am and 8pm.
It means the other centres, in Ballyshannon Co. Donegal and in Dublin will operate as normal.
The Communications Workers Union has indicated that it remains open to dialogue, with a view to resolving the issues at the centre of this dispute, namely a living wage of 11.50 an hour, a fair on-call policy and collective bargaining.
