Which principle of bureaucracy did the employees violate

Standardized rules and procedures

Explanation:

The bureaucracy sets standardized standards and procedures to be developed during the work. When a superior tells the employee what should be done after each work activity, he / she is establishing the standards and standardized procedures for that activity.

In such a case, when an employee is told that certain documents should be destroyed immediately after being read as a safety precaution and that employee does not destroy those documents, the employee is violating the bureaucratic principle of standardized standards and procedures.
