The Executive Council of the Irish Nurses and Midwives Organisation (INMO) have decided to hold off on making a recommendation on the proposals for pay restoration.
The decision comes amid concerns about inadequate recruitment of additional nurses.
Last April, the Health Service Executive, the INMO and SIPTU agreed a target of 1,208 additional funded nurses to be recruited by the end of December 2017 to plug vacancies across the health service.
The organisation said that recruitment remains very low and retention continues to be problematic.
The Executive Council also expressed frustration that the organisation is being put through a "tedious process" of having to ensure that the national agreement is implemented in all locations.
Dave Hughes, INMO Deputy General Secretary commented: “There is huge frustration among the nursing and midwifery workforce on the frontline at the slow progress in providing adequate numbers to care for a growing number of patients.”
Phil Ni Sheaghdha, INMO Director of Industrial Relations said: “In spite of a National Implementation Group, operating at senior level, progress is slow at regional level and the barriers to recruitment and retention remain. The INMO is committed to working proactively with the HSE and the Department of Health at national level throughout the summer months to get a workable implementation process at regional and local level.”
