The Government's e1bn public sector pay-cut plan has further support after gardai and nurses gave it their backing.
The Garda Representative Association (GRA) and the Irish Nurses and Midwives Organisation (INMO) have both voted in favour of supporting the Haddington Road agreement.
The deal – the successor to Croke Park – will see public sector pay cuts of e300m this year and e1bn over three years.
GRA general secretary PJ Stone confirmed 84pc of members voted in favour of the deal drawn up by the Labour Relations Commission. Almost three quarters of the INMO – 71pc – voted to support the deal.
The GRA and INMO join Siptu and the Irish National Teachers' Organisation, the largest teaching union, in supporting the proposals.
The executives of the Association of Secondary Teachers of Ireland and the Teachers' Union of Ireland have rejected the Haddington Road deal and not put it to a ballot.
The Unite trade union, which represents about 6,000 people in the public sector, put it to a vote and members refused to support it.
The Government has warned that it will impose unilateral pay cuts if unions do not support the Haddington Road Agreement.
