The Teachers Union of Ireland is to recommend its members reject the new public sector pay deal.
It follows a meeting of its executive committee yesterday evening, which heard that the proposals did not allay a number of significant concerns.
Union members will be ballotted on the measures hammered out last week in the Autumn.
The union says second-level teachers are "frustrated and disillusioned by the extra hours of bureaucracy and administration".
Lecturers at institutes of technology are said to be experiencing high levels of stress due to additional 'flex' hours introduced by the Haddington Road Agreement - with 'a multiple of hours in terms of preparation and associated work' said to also be required due to the additional two hours of lecturing.
Gerry Quinn is the President of the TUI. Speaking to Shane on Coleman on today's Pat Kenny Show, he explained that they are objecting to provisions in previous pay agreements being kept on for the new deal:
However, the Public Expenditure Minister this morning defended the Lansdowne Road Agreement.
Minister Brendan Howlin says the deal is a fair one, and it will keep ‘peace’ with the public sector in a responsible way:
The proposals agreed last week by unions and government representatives will see most public servants having their pay restored by around €2,000, over three phases between January 2016 and September 2017.
The agreement - which will be known as the Landsdowne Road Agreement - will also see the protections of the Haddington Road Agreement extended to September 2018.
