The council of the doctors' union, the Irish Medical Organisation, is to call for rejection of the Lansdowne Road Agreement.
The union said last night it will hold a ballot on the proposals.
President of the union Dr Ray Walley said that IMO Council had no option but to vote to reject the agreement and to recommend rejection.
"It does nothing to address the real crisis in our health services - the inability of the system to retain existing doctors and attract new doctors.
"Our highly trained doctors are much sought after and valued by other countries where they are resourced to carry out the work for which they have spent long years training.
"This is bad for the future of our services but, more importantly, it is creating serious safety issues with long waiting lists and insufficient resources" he said.
Dr Walley said the IMO has continuously warned Government of the "inevitable consequences of the basic unfairness of two-tier pay".
He added: "Even now, when we have vacancies all over the country, the Government still refuses to address the principle of equal pay for equal work".
He said while the IMO had worked with Government to address these issues through the new entrant consultant agreement, it was being "blocked and hampered" by Government Departments adding: "Doctors have no confidence that anything has changed."
