There are a few different ways to set up how Time Off requests are approved and by whom.
If no other approval set up has been done all requests, for policies that require approval, will go directly to the line manager.
Only have one person who approves Time Off requests?
You can appoint a sole approver to replace all direct managers here:
Have a two-step approval process?
Once you've flicked the switch on two-step approval, indirect managers will be appointed as the second approver by default. However, you can also appoint a sole second stage approver to replace all indirect managers.
You can now set custom approvers on bob. To view the first and second approver you can select to see them through the column picker.
