Overcrowding in hospitals should be treated as a "national crisis", the Irish Nurses and Midwives Organisation (INMO) has said.
INMO General Secretary, Phil Ní Sheaghdha, said the same problem arises every year and is "not acceptable".
The INMO will begin to consult nurses and midwives on possible strike action next week in response to the overcrowding crisis because their working conditions are "so bad".
