How can I assign time off by Workplace, Department, or to The entire company?
If you want to assign time off by Workplace, Department, or to The entire company, go to Configuration >> Calendars >> Time off.
As the new time off will be "empty", click on "Add" and assign the time off by Employee, Workplace, Department, or to The entire company.
Note that if this time off is already assigned to an employee, workplace, or department, you will only see those entities that have not yet been assigned.
Moreover, when an employee is registered or a user is added to a specific workplace or department, time off will also be automatically assigned to that entity.
