The Irish Medical Organisation is to ballot its public service members with a recommendation to reject the Croke Park proposals.

The IMO was one of four unions that walked out of the talks before their conclusion.

The council of the IMO decided unanimously to hold the ballot and to recommend rejection.

They also endorsed the decision of IMO negotiators to walk out of the talks.

The Croke Park deal is aimed at cutting an additional €1bn from the State payroll bill over the next three years.

SIPTU’s National Executive Council yesterday deferred a decision on whether to recommend the proposals to members until 14 March.

SIPTU president Jack O'Connor described the proposals as the most controversial proposition that trade unions have ever had to consider.
