Minister of State Brian Hayes has indicated that all of the €300 million in savings from the public service being sought for 2013 may not be reached this year under proposals currently being examined at the Labour Relations Commission.

He said the big objective was to get savings of €1bn euro between now and 2015.

Mr Hayes said negotiators are now looking at alternative plans which will still achieve that figure but may require some changes to the amount to be saved for this year.

He said the Cabinet is due to be briefed on Tuesday as to how the process is going.

Mr Hayes also said the talks on finding a successor to the Croke Park agreement were at a crucial stage and hoped agreement can be reached in the next 48 hours.

Meanwhile, the Executive of the Irish Federation of University Teachers is to hold an emergency meeting tomorrow morning to discuss whether it will enter talks on a revision of Croke Park II

According to IFUT General Secretary Mike Jennings, members are angry that they provided enormous concessions on productivity as part of the original Croke Park proposals, on the basis that there would be no further pay cuts or related demands.

Three of the other teachers unions - the INTO, TUI and ASTI - have all said they will attend the LRC tomorrow for talks.
