Members of the Irish Nurses and Midwives Organisation (INMO) in St Camillus Hospital, Limerick suspended their work-to-rule from 8am this morning.
The decision follows an interim agreement reached at the Workplace Relations Commission (WRC).
According to the INMO, the HSE has agreed interim rosters, with the INMO and SIPTU, which acknowledge the staffing requirements.
"Intensive efforts are being made to recruit the additional nurses required," an INMO statement read.
"Other measures related to the permanent filling of nurse manager posts and professional development will be progressed.
"The HSE has committed to monitoring, on a daily basis, the admission of patients in tandem with the availability of staff."
The Workplace Relations Commission has agreed to reconvene the parties for a review next Monday.
