Amicus, the trade union representing staff at non-commercial semi-State bodies, has called for taxi-drivers to be paid mileage for driving to and from Arklow, where they will have their taxi meters certified every year when decentralisation goes ahead.
Currently taxi-drivers, the majority of whom live and work in Dublin, have their meters certified at a centre in Ballymun.
However, the Legal Metrology Services department of the National Standards Authority of Ireland, which certifies meters, is to be decentralised to Arklow. Amicus, which represents the metrology services staff, has said the planned move is "absurd".
Mr Frank Barry, chairperson of Amicus's public services committee, said: "People are going to be out of pocket with the cost of travelling to another county to get their meters checked, not to mind the extra inconvenience involved."
