The allocation of employees to managers is only used for the holiday request process. Holiday requests are sent to allocated managers. Employees can also be allocated to an administrator who has wider permissions than a manager.
A user can be allocated to one manager or several managers. Managers and administrators should also be allocated to a manager. Upon initial registration, the administrator is allocated to him/herself. This can be changed as soon as other users (such as a line manager) are created.
Managers and the administrator can be allocated to themselves if they are free to authorise their own holidays.
