The INMO says plans for reopening society need to include extra capacity and supports for burnt out and exhausted staff.
It's after the union described the overcrowding at Cork University Hospital as "out of control and extremely dangerous".
738 patients were forced to wait on trolleys at the hospital's Emergency Department in August, with the INMO warning the figure is having an impact on infection control.
The hospital say they are taking measures to tackle the overcrowding and are asking people to consider all options before turning up at the Emergency Department.
Speaking to RedFM News, Liam Conway from the INMO in Cork says more resources are urgently needed.
"It's extremely difficult for our members, they're already burnt out.
"Even for example if we look at maternity services as well, there's staffing deficits here in the maternity service here in CUH, and they've seen one of the biggest demands that have ever been placed in their service.
"There's huge demand for service at present, and there's simply not enough staff, not enough services, not enough out of hours services, and obviously not enough beds as well.
"That's really creating a serious difficulty for members and a very dangers environment in terms of a work place for Covid-19>"
