As an Administrator, you can set it up so that managers can approve or decline holiday requests direct from the email. To do this, please follow the steps below:
- Click the 'Settings' tab
- Ensure you're in the Holiday & Absences tab
- Scroll down and check the box, which says 'Authorise Holidays from Email':

To learn how a manager can approve holidays via the desktop or through email, please see: http://help.peoplehr.com/holiday-entitlements-requests/approvedecline-holidays
