The Minister for Transport has called for the uncertainty over Kenny Jacobs' position as daa chief executive to be brought to a conclusion as "expeditiously as possible".
Darragh O'Brien said he wants to see "a resolution one way or the other" and "as quickly as possible".
An exit deal was reached between Mr Jacobs and the board of directors of the operator of Dublin Airport and Cork Airport in mid-September, after a mediation process.
The agreement, which requires approval from the Minister for Transport and the Minister for Public Expenditure Jack Chambers, has not been signed off.
It is believed Minister O’Brien is reluctant to approve the severance package, amid concerns such a move could set a precedent.
The deal is estimated to be in the region of €1m, given the period of time remaining in Mr Jacobs' contract.
The minister wrote to the daa board last week urging the two sides to consider further mediation in a bid to reach a reconciliation, but it is understood the board indicated its position had not changed.
Speaking at an event in Dublin this morning, Darragh O’Brien would not be drawn on the matter other than to say he has "asked that this situation be brought to a conclusion as expeditiously as possible".
He said the issue is a matter between the chief executive and the board of the daa.
"I'd rather that that be worked through between the board and indeed, the executive in Dublin Airport Authority, which is a very successful state enterprise and a really critical part of our infrastructure, both Cork and Dublin Airport indeed," Mr O'Brien said.
"All I will say is that I have been engaged with the board on this. I have met with the chairperson and the board. I want to see a resolution one way or the other," he added.
"I know the board, and indeed the chief executive will work towards that, and I want to see that done as quickly as possible."
The exit deal followed a breakdown in relations between the daa boss and members of the board, which is chaired by Basil Geoghegan, in relation to two protected disclosures against Mr Jacobs.
The complaints were not upheld, after being investigated.
Kenny Jacobs, who is currently due to leave his role leave in the new year under the agreement on the table, is continuing to run the daa.
The 51-year-old, who previously worked as chief marketing officer at Ryanair, was appointed as chief executive of the daa in November 2022.
Mr Jacobs took up the role in January 2023, meaning he has served less than three years of his seven-year term.
