If a staff member does not have any absence showing on their profile or on Staff absence reports, this may be because there was no absences recorded in the timeline being looked at. i.e. 2017-2018. To check the dates in question, you are able to go to Admin>Personnel>Manage Staff Attendance
If there are Absence codes entered for the staff member on the dates in question, you are able to go to the profile, click on the white cog beside the word Absence and add the data here.
