Fórsa, the country's largest public sector trade union, is recommending acceptance of the public sector pay deal agreed earlier this week.
The union's national executive has voted overwhelmingly to recommend that its members vote in favour of the proposals.
Fórsa is to commence a ballot of members next week and voting will conclude in early October.
The pay proposals will see public sector workers receive an increase of 6.5% across this year and next year.
A 3% increase would be paid this year, backdated to February 2022. That would be followed by 2% from March 2023 and 1.5% or €750, whichever is the greater, from October 2023.
This is in addition to increases of up to 3% agreed under the existing public sector pay deal 'Building Momentum'.
Fórsa General Secretary Kevin Callinan, who led the union side in the talks, said his executive accepted that the deal was the best that could currently be achieved through negotiations.
"We'll now be explaining this package to Fórsa members, who will decide the union’s position when a final decision is taken next month," Mr Callinan said.
"While neither side achieved all it sought in the negotiations, this package is a significant improvement on the pay terms of Building Momentum," he added.
Fórsa said workers expect the Government to honour its promise to supplement pay measures with cost-of-living supports in the forthcoming budget and a failure to do so could affect the outcome of the ballot.
