Like-for-like replacement

I currently work at a hospital operated by St John of God.  What is the like-for-like replacement policy when absences occur?

Clause A8(c) of the St John of God Health Care Hawkesbury District Health Service and New South Wales Nurses and Midwives’ Association/ANMF NSW Branch Nursing and Midwifery Enterprise Agreement 2017 sets out that when a nurse or midwife is absent and a replacement needed, the level of skill required will be determined by the NUM or ward management based on operational requirements.  If ‘like-for-like’ is found necessary (e.g. registered nurse for a registered nurse), the hospital will need to undertake all reasonable avenues to fill this requirement.
