Tánaiste Eamon Gilmore has warned against a "season of kite-flying" in advance of December's budget.
Mr Gilmore said last year there had been a leak a day about what might be in the budget, which he said was unfair, particularly to the elderly worried about what it might contain.
Pointing out that much of the speculation was inaccurate, Mr Gilmore said he hoped there would not be a season of kite-flying and leaks in the run-up to the Budget.
Asked about a suggestion by MEP Nessa Childers that the party could split, Mr Gilmore replied: "That's news to me".
He said he was "absolutely confident" in the support of the party in taking tough budgetary decisions.
Mr Gilmore added that he was confident that when they met this time next year, Ireland would be on the eve of exiting the EU/IMF bailout programme.
Earlier, he said there will be no "unilateral withdrawal" by the Government from the Croke Park Agreement, indicating it could jeopardise a follow-up to the deal.
Speaking on RTÉ’s Morning Ireland, he said the deal was constantly under review and that is what was going on at the moment.
He said there had already been significant pay cuts under the agreement.
Mr Gilmore said what the agreement did was say there would be no more such cuts, provided there was co-operation in cutting numbers and getting the work done.
The Tánaiste said not keeping the agreement could endanger any possible new Croke Park deal with unions.
He said change had to be achieved through co-operation and rejected any suggestion that the public service had a "veto".
"If you make an agreement, you keep the agreement, and there's a good reason for that. Because if you break an agreement, the people you make it with are unlikely to reach agreement with you again," he stated.
Mr Gilmore also said that he had confidence in Minister for Health James Reilly.
He said that the health portfolio was a difficult one, which was in need of reform, and that Mr Reilly was leading that effort.
"He has my support and the support of the entire Government," Mr Gilmore said.
Mr Gilmore also rejected any suggestion that the Government would stall in making a decision on abortion.
He said there was an obligation on it to act following a European Court judgment, and that it was waiting for a report from the Government-appointed expert group on the issue.
Meanwhile, education and children's rights topped the agenda at the final session of the party's seminar before the start of the new Dáil term next week.
TDs and Senators, who met in Maynooth, Co Kildare, also discussed the national broadband plan.
The first discussion today was about education, with Minister for Education Ruairi Quinn outlining his plans to achieve equality through reform.
Minister for Communications Pat Rabbitte led the discussion on the national broadband plan.
The main speakers for the discussion on the children's rights referendum were Fine Gael's Minister for Children Frances Fitzgerald and Fergus Finlay of Barnardos.
