The Irish Nurses and Midwives Organisation will meet today to discuss its plans for a series of 24 hour strikes.
95 per cent of nurses and midwives voted for industrial action last month in a row over staff shortages and pay.
If a national strike goes ahead, it would see INMO members providing only lifesaving and emergency care.
Finance Minister Paschal Donohoe has said a pay rise for nurses would be "unaffordable and unsustainable".
Professor of Employment Law at Maynooth University, Michael Doherty, says it's difficult to see how the strikes can be avoided.
