Rank and file gardaí are to cease working the additional 30 hours a year that were imposed in the Haddington Road Agreement from 1 January 2016.
Last week, the Garda Representative Association and the Association of Garda Sergeants and Inspectors rejected the Lansdowne Road Agreement negotiated in May this year between the Government and public service unions this year.
The GRA leadership today decided members will cease performing the 30 additional Haddington Road hours.
This was an obligation which was due to expire at the end of this year, but which would have continued under the LRA had it been accepted.
Sources expressed frustration that a review of Garda pay and industrial relations which was due to be completed by 1 January 2014 under the terms of the Haddington Road Agreement still has not been completed.
They said the GRA wants that review completed by the end of February 2016 at the latest.
The GRA will also be seeking ongoing reviews of Garda pay, and access to the dispute resolution mechanisms of the Workplace Relations Commission in line with other public servants.
