uPaged nurses are employed as a casual employee by your hospital. Your hospital is their employer.
When a uPaged nurse is accepted and booked into a shift for the first time, your HR department will receive an email notification to onboard the nurse. The onboarding process includes sending a casual contract to the nurse to sign.
This means the nurse becomes your hospital's casual employee. They will be paid by your hospital's payroll system and covered by the hospital's insurances.
uPaged nurses are not employed by uPaged.
