INMO members are set to take nationwide action from March 7th
The Irish Nurses and Midwives Organisation (INMO) has said its members not looking for a pay rise.
Following a meeting of their executive committee yesterday, the organisation said it will exercise the 90% mandate it received in a ballot of its members before Christmas.
It will serve notice of nationwide industrial action commencing on Tuesday, March 7th.
The action will take the form of "an immediate and continuous work to rule" involving nurses and midwives working to contract.
In addition, the organisation also say it will commence a series of rolling stoppages if the dispute is not resolved.
The nursing union says industrial action which starts next month is over the ability to attract and retain staff.
INMO General Secretary Liam Doran told Newstalk Breakfast: "The key demand, let's be quite clear, is measures that will attract and retain nurses & midwives.
"If you can't get them in on current arrangements, you have to get more money - but we're not seeking a pay claim."
The Health Minister, meanwhile, says the last thing the health service needs is industrial action.
Speaking in the Dáil, Minister Simon Harris says he is determined to avert the work-to-rule.
"They've now provided three weeks and six days before a work-to-rule takes place across the Irish health service," he said. "A work-to-rule I believe - and the INMO have conceded - would be detrimental to Irish patients.
"You only resolve any dispute by sitting around a table and trying to sort it out. What we don't need in the Irish health service, what nobody needs, is industrial action," he added.
