Re: union nurse vs nonunion non-nurse
There are layers that are a bit hard to figure here, so I'm having to make assumptions.
I'll assume that the reason nurses are doing the job now is that you are analysing medical info and it requires your knowledge background to do it properly.
Depending on your contract, the fact that there is a past practice of having this be a nurse job may give some leverage for a grievance against hiring a non-nurse for the job.
In our union, we'd probably file the grievance to preserve the right to while we were deciding whether or not to proceed with it - you can always withdraw a grievance, but there are time limits on filing them.
if there are several nurses with similar job - it sounds like that's the case? - then consider a campaign via petition, asking for meeting with your manager, etc.
There is almost certainly no legal barrier to this, since you aren't performing actual patient care activities, it's your nursing knowledge that's needed, not your nursing license. So likely no regulatory angle to pursue.
In all your actions, important to de-personalize: not against an individual, but for a principle.
In general, outright refusal to orient the person is a bad idea. Once you venture into the area of insubordination, you can create a situation that's hard to defend. I never advise nurses to outright refuse something, unless there is real danger to a patient. Better to do it while documenting the reasons you believe it is wrong.
