The Health Minister Simon Harris has said he intends to turn down a €4,000 pay rise.
Government Ministers are set to reject the increase, which will otherwise kick in on April 1, at a cabinet meeting tomorrow.
Junior Health Minister Finian McGrath has said TDs need to "stop whinging" and also give up their €2,700 pay rise.
Minister Simon Harris agrees, but added TDs pay should stay linked to the Civil Service.
He said: "TDs being linked to civil service pay - going down when they go down and going up when they go up - largely serves the country well.
"Politicians setting their own pay - I don’t think that's a good policy.
"I certainly have no intention of taking the increase."
