Yes, you can cancel a shift by going to your 'booked shifts' and selecting the cancel button on that shift.
That said, uPaged takes cancellations very seriously as it can mean that a hospital is not able to find a replacement to care for their patients. Similarly, when a hospital cancels a nurse with short notice the nurse may not be able to find a replacement shift, resulting in a loss of income. Our aim is to create transparency around this. If a nurse or hospital cancel a shift within four hours of the shift start time, this will be recorded in a cancellation rate on their profile, to help everyone make the best possible decision next time they choose.
