Employees are unable to delete their own sickness records - this will need to be done by either the employee's manager or a system administrator.
If a system administrator has a manager, the same rule will applies - either their manager or another administrator will have to delete this.
To delete an employee's sickness:
Click on the 'Employees' tab
Find and click on the specific employee
Locate the sickness entry you wish to delete and click on it
A delete button will then appear in the bottom left-hand corner.
