Civil servants working in An Garda Síochána will expect matching pay increases if gardaí are awarded rises in an upcoming review of their pay and conditions.
Gardaí are currently refusing the work the additional unpaid hours imposed under the Haddington Road Agreement.
However, addressing the Civil Public and Services Union Annual Delegate Conference in Killarney, General Secretary Eoin Ronayne said that any deal agreed for gardaí as part of that review would be seen by the union as having knock-on implications for them.
He said there was "no special bubble" for any grade in the Gardaí.
Deputy General Secretary Derek Mullen added that civil servants would find it hard working alongside garda officers who were not currently working the additional hours imposed by the HRA.
Separately, Mr Ronayne said that in a period of economic growth the union would seek to have elements of the Lansdowne Road Agreement brought forward - including the €1,000 payment due in September 2017.
Delegates also passed a motion calling for a ballot for industrial action if the government did not implement full restoration of pay within six weeks of the expiry of the LRA.
Earlier the conference heard that new entrants to the civil service are earning up to €7,000 a year less than their longer serving counterparts on the same grade, according to the CPSU which represents 12,000 low-paid civil servants.
The union has criticised the lower pay rates introduced for new entrants during the recession - and has joined other unions in calling for accelerated restoration of all cuts in pay and conditions.
Mr Ronayne said the lower new entrant scales meant a new recruit starting on €9.70 an hour would take six years to reach the living wage of €11.50.
He described the €9.70 starting rate as unacceptable, particularly as such workers had no opportunity to boost their incomes through allowances or other premium payments.
He claimed that new recruits - including some with third-level qualifications - were leaving the public service when they realised it could take 18 years to attain a salary level of around €35,000.
He said this phenomenon was particularly evident in Dublin.
In his speech, CPSU President Tony Conlon called on the incoming government to repeal the financial emergency "FEMPI" legislation underpinning the cuts in pay and conditions in the public service.
He noted that private sector workers who had not had pay cuts were now receiving increases of up to 3% - adding the civil servants were only seeking restoration of pay cuts.
Delegates will also be discussing the imminent loss of 1,200 members as the Staff Officer grade represented by the CPSU is merged with the Executive Officer grade represented by the Public Service Executive Union.
The Transfer of Staff Officers to the PSEU will mean an annual loss of subscription revenue of around €500,000 for the CPSU.
At last week's PSEU conference, delegates voted to launch a claim for extra annual leave to compensate for the fact that in future, members will face extra competition for promotions from the 1,200 staff officers transferring in.
