The Secretary General of the nurses and midwives union says he has never been as worried heading into a winter period.
Liam Doran was speaking as the INMO prepare to consider balloting for industrial action tomorrow.
Union members met with Health Minister Leo Varadkar earlier, who said he does not see how industrial action will help patients.
Liam Doran from the INMO says that there needs to be an increase in the numbers of nurses and beds to ease the crisis.
"I always try to be an optimist but I've never been as concerned going into a winter period.
"I mean all the indicators are that the overcrowding is getting worse, our staffing levels are very low, our ability to recruit is very limited, the management side and the government have not yet got the fact that they need to make recruitment and retention an absolute priority."
