Members of the Irish National Teachers' Organisation (INTO) and the Teachers' Union of Ireland (TUI) have voted to accept the new public sector pay deal.
Last month, the Government reached agreement with unions and staff associations on a set of proposals that would see public sector workers receive a 6.5% pay increase over two years.
The deal would deliver increases of 3% backdated from 2 February 2022, 2% from 1 March 2023 and 1.5% or €750, whichever is the greater, from 1 October 2023.
This would come on top of a 2% increase already included in the existing public sector pay agreement, 'Building Momentum'.
After agreement was reached, the Irish Congress of Trade Unions (ICTU) said that individual unions should ballot their members on whether to accept or reject the deal.
Today, the INTO said that 57% of its members cast ballots and of them, 80% voted in favour of the deal with 20% voting against.
"After prolonged and intensive negotiations, we secured an agreement that our members have welcomed as it will provide significant salary increases and pay certainty," said INTO General Secretary John Boyle.
"We will be determined to ensure that any successor agreement negotiated after Easter addresses outstanding union claims and further improves the pay and conditions of our members, who always give their utmost to provide the highest quality learning experiences in our primary and special schools," he added.
TUI members voted by a margin of 85% to 15% to accept the proposals.
Other public sector unions are due to announce the results of their ballots in the coming days.
The results will then be aggregated at a meeting of the ICTU Public Services Committee on Friday 7 October.
