The "Employee Visible" column indicates if the Employee can see the document on the Employee Experience. This value is calculated whenever the Documents page loads and is not stored in the database and therefore it cannot be reported on.
Depending on the User Role rights, this value may or may not appear within the Information Panel. In order to view the Employee Visible section on the Information Panel, the user role must have access to <Documents - Visible on Employee Experience Override> screen section rights.
