By design, when an employee submits Emergency Time Off it show up on the Employee Schedule in the Absent section.
Emergency Time Off does not open an employee flag since there's no way to dismiss (approve or deny) Emergency Time Off until the employee has submitted an excuse. It is now the employees responsibility to upload an excuse before the Emergency Time Off day can get approved or denied by the Office Staff.
What determines when your Emergency Time Off request appear for requested time off, is determined by the number of hours you have set under Company > General > Employee Schedule Settings > Hours Before Shift Considered Emergency.
