Some facilities would allow you to just add leave and it will be approved automatically. In most circumstances you will be requesting leave for another person to approve.
To request leave - follow the instructions here:
1. Either click on Leave on the left pane menu (A) or click on Profile under the profile's name(B).
2. On the next screen, click on Request Leave (C).
3. Make sure that the leave type (i.e. Annual, Sick, Carer, etc.) and the leave dates are correct (D). There is also an option to attach files (i.e. leave form, approvals, etc.) (E).
Save the leave request (F).
4. All pending and approved leave requests are in the Dashboard.
