Final answer:
A CMA is generally allowed to bypass the chain of command in the event of an ethical conflict involving their supervisory authorities, to ensure impartial resolution and to maintain organizational integrity.
Step-by-step explanation:
The statement that a Certified Management Accountant (CMA) is permitted to bypass the chain of command if their supervisory authorities are involved in an ethical conflict is, in general, true. Ethical guidelines often permit escalation of the issue to higher levels of authority, including independent committees or external bodies, when there is a conflict involving immediate supervisors.
This is to ensure that ethical conflicts are resolved in a manner that is impartial and maintains the integrity of the organization. However, it's important to consult with the specific code of conduct or ethical guidelines of the profession or organization concerned, as procedures may vary.
