Nurses at one of the country's busiest hospitals have served notice of industrial action, and will work to rule later this month.
Members of the Irish Nurses and Midwifery Organisation at Beaumont Hospital in Dublin voted in favour of industrial action last night.
Their decision came after after a day which saw record numbers of patients on hospital trolleys nationwide.
The overcrowding at Beaumont Hospital led to the decision by all INMO members there for a work-to-rule on January 27th.
Ballots by other members at four other hospitals will take place later today.
The General Secretary of the INMO Liam Doran said public beds need to be re-opened and more staff needs to be recruited to deal with the problem.
