The Garda Representative Association has voted overwhelmingly that they are willing to take industrial action if their pay demands are not met.
Over 95% of the 6,000 members that took part in the ballot said they were in favour.
The ballot was arranged earlier this month, before a draft agreement on a pay deal between the Department of Justice and the GRA was reached last Friday.
That agreement is to be discussed at a meeting of the GRA executive tomorrow.
GRA President Ciarán O'Neill said a draft deal reached with the Government over the weekend has been brought to the central executive committee and will be presented to members of the GRA at its delegate conference tomorrow.
Speaking on RTÉ's News at One, Mr O'Neill said that the executive has not made a recommendation, yet, to its members and that he cannot predict if members will accept the deal.
He said that members want pay to be restored but this will not be done under the Lansdowne Road agreement. There would be some restoration of pay but it did not go far enough, he added.
Mr O'Neill said it was for the membership to decide whether the deal was acceptable but there was a huge level of anger and frustration among gardaí.
He said that members do not feel they are seeing the benefits of improved economic circumstances.
Mr O'Neill said that no one else puts on protection gear going into work and the GRA did not see the Lansdowne Road agreement as the "only show in town."
He added that the Lansdowne Road deal needs to be revisited and that the special role of gardaí has to be acknowledged by Government.
"We don't see that the Government are seeing us as a unique role. We're being tied in with every other public service employee. I think Lansdowne Road needs to be revisited."
