Implementing Leave Management
In addition to managing and approving daily timesheets, it is also possible to install an Odoo Human Resources application that will manage holidays, leave, and other information related to employee time off. We install Leave Management
in the same way as we installed the other Odoo applications:

After you have installed the Leave Management
application, you will have yet another new menu, the Leaves
menu. One departure from earlier editions of Odoo is that now Odoo installs many of the Human Resource applications as separate menus. This leads to having more and more main menus within the Odoo application. Fortunately, however, the menu automatically collapses down into a drop-down list when there is not enough room to display the menu horizontally across the screen:

The primary purpose of this Leave Management
application is to provide an easy mechanism for employees to request leave and for their managers to approve or deny the request.
