Just two unions have backed the proposals to slash €1bn from the state payroll.
The fate of the pact will not be decided until Wednesday when all 20 unions have issued their ballot results.
The big players – who hold the greatest voting strength – SIPTU and IMPACT – will not issue their verdicts until tomorrow at the earliest.
Earlier today, four unions rejected the deal after three unions voted against it in recent weeks.
Two unions whose members face pay cuts over 5.5pc or more under Croke Park II overwhelmingly rejected the proposed agreement.
The Irish Federation of University Teachers (IFUT) and the Association of Higher Civil and Public Servants (AHCPS) voted against the deal.
IFUT rejected it by 75pc, with 25pc in favour, while the AHCPS balloted against it by a majority of 85pc, with 15pc in favour.
Both unions hold just a 1pc share of the 20 public service unions’ votes each.
The UCATT, representing construction workers, has also rejected the deal.
General Secretary of the AHCPS, Dave Thomas, said the proposals were not fair and accused the government of “heavy handed interventions” that had only served to strengthen the no vote.
He said an assistant principal officer earning €69,884 will see a loss over the three year deal of €24,630, while a principal office on €84,132 would be down €34,931.
The Civil, Public and Services Union, representing 13,000 lower-paid civil servants, also rejected the deal.
The union, which has a four percent share of the vote, voted by 87pc against it, with 13pc in favour.
The Teachers' Union of Ireland, the Medical Laboratory Scientists Association and the Technical, Engineering and Electrical Union have already rejected the deal.
Earlier, two unions representing construction workers and plasterers became the first to back the proposed deal.
The Building and Allied Trades Union, representing 125 construction staff, have voted in favour of the deal by 72pc to 28pc against.
It said a key factor was the fact that its members' basic pay would not be hit by the proposals.
OPATSI, which represents over 50 plasterers in local authorities, the HSE, OPW and Department of Defence, said 66pc voted in favour, with 34pc against.
"If this deal isn't accepted the first thing government will do is make staff compulsorily redundant, and I've no doubt they'll hit our members first," said General Secretary Billy Wall.
However, both unions are among the smallest of the public sector unions, and hold less than 1pc of the vote each.
The proposals, if ratified by all public sector unions, will mean pay cuts for public servants earning more than €65,000-a-year.
They also mean freezes and delays in the payment of increments, extra working hours, cuts in premium pay, and more flexible redeployment arrangements.
The government has warned it will legislate for pay cuts, in the region of 7pc, for all 290,000 public servants if the agreement is not carried.
The final result will be revealed when the Public Services Committee of the Irish Congress of Trade Unions meets on Wednesday.
