45,000 HSE staff and former workers are still waiting for increments that were promised to public sectors workers over 12 months ago.
That's according to Senator Robbie Gallagher who says hundreds of staff across Cavan and Monaghan have also been impacted.
He says the agreement has seen other public sector workers like Gardai and teachers paid their wage increase but those working in the HSE have been left in limbo.
Speaking to Shannonside Northern Sound this week, Senator Gallagher said the situation is "unacceptable" and he highlighted how HSE staff and pensioners are now owed between €1,500 and €2,000 each.
He added that he has written to the Minister for Health, Stephen Donnelly, asking him to address the matter with the utmost urgency.
"When I looked into this all the HSE employees and indeed HSE pensioners, some 45,000 people involved here, are still waiting on their increments 12 months on and we're talking a sizeable amount of money here. We're talking anywhere between €1,500 to €2,000 which is a significant amount of money and it's very disappointing because these healthcare workers, doctors, porters, physiotherapists, caterers, are the people we lauded, and rightly so, during COVID".
