No "agency scene"? Could be a business opportunity for somebody, then (although the market may be a bit small).
How about "freelancers" ... are they tolerated?
"Coming over to train" ... could be short-term (presumably); "locums", then. Greybeard biomeds from Oz taking a break, perhaps.
How is it in NZ ... are in-house biomeds directly employed by the government hospitals (Health Boards, whatever)? Who looks after the small government hospitals and clinics?
Is much use made of service contractors?
Are there many private hospitals (and clinics)? Do they have their own biomeds?
