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 was instrumental in negotiating a new pay deal for officers. It is considering becoming a fully fledged union once the current pay issue is resolved.
