Make sure the approver is set correctly
First, make sure that the employee who is submitting the leave has the correct line manager or leave approver set up on their post.
To do this:
Search for the employee submitting leave and go to their profile.
Click Position then click Post Details.
Click Approval then click Approvers.
Click Edit next to Reports To (Line Manager).
Select the relevant post that needs to be line manager for this post.
Click Edit next to Leave.
Select the relevant option for the leave approver.
Check the approver's work email address
It is also possible that the approver doesn't have the correct email address added in the system and because of this they are not receving leave approval emails.
To resolve this please refer to our article on changing an employee's work email address.
