The deal saw a threatened strike action averted earlier this month
Garda sergeants and inspectors will begin voting today on the Labour Court proposals that averted their strike action earlier this month.
More than 2,000 mid-ranking officers can vote in the ballot.
The Association of Garda Sergeants and Inspectors (AGSI) is recommending acceptance of the deal.
A result is expected by early December.
The AGSI and the Garda Representative Association (GRA) both called off threatened industrial action in early November.
Recommendations in the proposal are believed to include the introduction of parade duty payments, clarifications over annual leave - and a recommendation that the rent allowance removed from new entrants be restored, increased, and integrated into pay scales for all gardaí.
Speaking after the Labour Court talks, AGSI President Antoinette Cunningham said: "A fundamental and historic wrong has been put right tonight as a direct result of the sustained four-year AGSI campaign to gain access to the Workplace Relations Commission and the Labour Court.
"This has always been a key part of our commitment to members and that commitment intensified in recent weeks."
The offer said to be worth up to €3,639 a year.
