Talks aimed at averting next week's strike by 10,000 health support staff have adjourned but will resume on Monday afternoon.
SIPTU Health Division Organiser Paul Bell said there had been no progress, but as there has been no great expectation, there was no disappointment.
Mr Bell said the parties had stated their positions and had a number of engagements.
He said SIPTU had accepted a Workplace Relations Commission invitation to return to talks on Monday.
The dispute will see around 10,000 health support staff stage a 24-hour strike next Thursday.
Speaking as he arrived for exploratory talks at the WRC, Mr Bell warned that the grades in question will not wait any longer for payment of wage increases, which they say have been due to members since 2018.
He noted that health support staff were due a total of €16.2 million, while chefs whose roles were assessed in a similar exercise were due €2.9 million .
Mr Bell said members were not talking about a mere "down payment".
He warned that if the strike of health care assistants, porters, caterers, cleaners and other support staff went ahead, 38 institutions would experience a significant impact.
Mr Bell stressed that his members had never deviated from the rules of the Public Service Stability Agreement and they expected the Government to honour its side of the deal.
He noted that if the Government did not do so, it would have serious implications for any future public service pay agreement.
He said members would query why they would enter into a future agreement when the Government believes it can select "a la carte" what it implements and what it does not implement.
Mr Bell also criticised what he called a "staggering" and "deafening" silence from Minister for Health Simon Harris on the dispute. He said he had no reason to be optimistic about the prospect of a resolution.
He said his message to the HSE was that they had agreed SIPTU’s members were owed these monies, and management must work with the Department of Public Expenditure and Reform to ensure payment.
The HSE the Department of Health and the Department of Public Expenditure and Reform are also attending the talks, but were not available for comment.
If the dispute is not resolved, SIPTU has scheduled five further days of strike action on 25 and 26 June, as well as 2, 3 and 4 July.
