If there are no authorisers available to sign off your shift via the app, you can do any of the following:
Request sign-off - this will send an alert to the department requesting them to sign the shift off remotely.
Get the shift signed off via the app when you’re next doing a shift.
Email your department manager, CC-ing in the consultant on duty at the time of your shift and include the shift ID in the email. The department manager will manually sign off the shift for you.
