We know things happen and sometimes you wont get the chance to post the shift on the platform before it happens. If you need to post a shift that has already happened you can do this on the platform.
To do this:
Select 'Post a Shift'
Select the unit you want to post the shift for.
Select the worker type.
Select the shift
Input the reason you need cover
Then you can select the toggle that says 'Shift Worked in the past'
This will allow you post a shift from a previous date.
