A ballot over strike action is underway among nurses and midwives in a dispute about understaffing and safety in the health service.
The INMO says low pay is making it impossible to recruit and retain staff, which is risking patient safety, limiting hospital capacity, and contributing to overcrowding.
Voting will take place in offices, hospitals and workplaces across Ireland until December 13th.
If the vote is passed, nurses and midwives will stop work for 24 hours.
Meanwhile, there are 386 patients on hospital trolleys around the country today - including 32 at University Hospital Galway, 21 at Sligo University Hospital and 11 at Mayo University Hospital.
