The nurses and the nursing union are definitely a major contributor to the malaise afflicting public hospital systems. The administrators/executive level staff - often nurses anyway - have to contend with nursing bureaucracies and entrenched cultures of laziness. You cannot do Mr. Smith's operation because we are on tea break.
More like; the list can't start because the Doctor hasn't shown up yet - he's still seeing outpatients in his rooms.
Or; there is an Emergency Caesar, followed by a Triple-A, and there is a car accident victim on it's way in, so Mr.Smiths colonoscopy will have to be pushed back until tomorrow.
You have to cancel Mr. Smith's admission because the assistant trainee nurse has called in sick
At this point the NUM is on the phone, calling every staff Member they have to see who can work. It's last minute, and many are not contactable, not available and/or have something else to do.
Next, she is calling up the various agencies to see who they can send. The agency rep tells the NUM that the earliest available nurse is 2 hours away, or no-one at all as it's too short notice, or no-one trained in that field to come in.
You have no clue.
Your Honor; the prosecution rests. No further questions.
