The country's psychiatric nurses have suspended their industrial action.
It followed talks between the Psychiatric Nurses Association and the HSE yesterday.
Nurses had been on an overtime ban since Thursday because of a dispute over recruitment and retention issues.
The PNA's Peter Hughes says the HSE has promised to fill vacant mental-health nursing posts.
He says they held intensive talks yesterday and made a lot of progress on a number of issues.
Talks with the HSE will continue early next week and are set to conclude on Wednesday.
After that the union will meet on Thursday to review the situation.
