As a manager, you have access to all the features of an employee, plus the opportunity to accept or decline your team members' leaves.
Time-off request notifications will appear in your email, and the leave of absence requests showcased on your Dashboard.
Overall all the functionalities you benefit from by using LeaveBoard as a manager are:
Within LeaveBoard, a user who supervises direct reports (usually above them in the organizational hierarchy) automatically gets manager access.
Just ask the HR leader who invited you to the platform to assign you as an approver, for your new direct reports from Employees > New employee > Profile.
From My account > Profile, you can see the employees you will have to approve the leave requests submitted by them.
