Which employees do not authorize destruction for any document? Give me their employee ids.
SELECT employee_id FROM Employees EXCEPT SELECT Destruction_Authorised_by_Employee_ID FROM Documents_to_be_destroyed
SELECT employee_id FROM Employees EXCEPT SELECT Destruction_Authorised_by_Employee_ID FROM Documents_to_be_destroyed
[{'Employee_ID': 25}, {'Employee_ID': 57}, {'Employee_ID': 71}, {'Employee_ID': 99}, {'Employee_ID': 136}, {'Employee_ID': 138}, {'Employee_ID': 159}, {'Employee_ID': 173}, {'Employee_ID': 181}]
