Over 11 and a half thousand Gardaí will be balloted on a vote of no confidence in the Garda Commissioner.
Drew Harris's leadership is being called into question over the recruitment and retention of officers during his tenure.
The Garda Representative Association has decided it will ballot members following the announcement of a return to pre-COVID rosters.
Vice President of the GRA, Brendan O'Connor says the decision wasn't taken lightly.
He said: Our members and our executive have decided to take this unprecedented step unfortunately to try and highlight the issues and [what is] the level of discontent in the force and legitamise our position on a number of topics.
[The topics] which have been disputed by senior management and has been told that our perception and our take on the situation is not reflective of our members.
