Health unions will hold the latest in a series of lunchtime protests as part of an ongoing dispute over staff shortages.
Demonstrations will be held at St Luke's General Hospital, Kilkenny, and at Connolly Hospital Blanchardstown in Dublin.
Protests were held last week in Dublin and Cork, and more are planned this week in Dublin, Louth and Offaly.
The group of trade unions, which includes the Irish Nurses and Midwives Organisation (INMO), Fórsa and SIPTU, has said that continuing recruitment restrictions in the health sector are putting patient services under enormous strain.
The unions said that the HSE's recruitment moratorium means that thousands of unfilled vacancies have effectively been scrapped, resulting in staff shortages that are having a detrimental impact on patient care.
INMO and Fórsa members will be balloted for industrial action from 14 October.
"While the HSE may maintain that the number of employees across the organisation has never been higher, the reality is that, against the backdrop of increased services and higher demands from an ageing demographic with more complex needs, the HSE remains under-resourced," said Linda Kelly, an official with Fórsa’s Health & Welfare division.
The ICTU group of healthcare unions is made up of representatives from the INMO, SIPTU, Fórsa, the Irish Medical Organisation, Unite, Connect and the Medical Laboratory Scientists Association.
"Our members will be protesting to highlight the fact that, despite talk of record-breaking levels of investment in the public health service, certain frontline roles have not benefitted to the same extent as others from that increased investment," said SIPTU Sector Organiser, Damian Ginley.
The HSE described the action as "regrettable" against the background of additional funding for the health service.
It said that its Pay and Numbers Strategy has enabled it to stabilise its workforce numbers and also allowed it to increase to 129,000 whole time equivalent staff by the end of 2024 (excluding disability services) which it said was unprecedented.
"We welcome the additional developments to be funded in 2025, which will add additional HSE staff to our overall workforce," a HSE spokesperson said.
"Each of the six HSE Health Regions and each national service has now been provided with its own specified number of whole time equivalent staff, and can within that approved number, replace and recruit staff according to the priorities in their regions."
"Against the background of such funding it is regrettable that the unions have given notice of protests, and of their intention to ballot," the HSE said.
