CNA stands for Certified Nursing Assistant or Certified Nurse Aid. These are people who are underpaid, frequently
unappreciated and provide
back-up and support to doctors and nurses. They are the people who do the menial or unpleasant jobs people don’t think about which, if they weren't done would make the patient’s life intolerable. They carry out this work without fuss or drama and usually bright, cheerful and efficient. They are often treated with disdain by nurses and frequently
berated by patients; despite this they do their work without complaint. Unkindly referred to as 'Cleaners of Nasty Arses' their work is essential to the effective running of both hospitals and care institutions.
