Lower -paid civil servants are seeking the Government to speed up the pace of pay restoration.
Their trade union also said the outcome of the Luas and Dublin Bus pay disputes, which resulted in pay increases, "needed to be reflected within the public service".
It also warned that tolerance of additional unpaid hours which public servants were obliged to work was “running out fast”.
The Civil Public and Services Union (CPSU)wants the €1,000 payment due from September next year brought forward to January.
The union, which has members working in clerical roles alongside gardaí in An Garda Síochána, said it would be watching developments carefully in the campaign by gardaí for improved pay and conditions.
Meanwhile Siptu president Jack O’Connor has said additional money that public service staff would be envisaged to receive under a successor to the Lansdowne Road accord after 2018 should be paid earlier.
He also urged the Government to bring forward the date for paying the second tranche of increases under the existing Lansdowne Road deal, which is currently scheduled to be paid in autumn next year.
Yesterday Minister for Public Expenditure Paschal Donohoe said the Government was worried about the possible “domino effect” of the planned Garda strikes.
Mr Donohoe said that any solution to public sector strikes must be through the Lansdowne Road Agreement.
