In what form must a mutual request be submitted, and what is a condition that does not allow this privilege?

The correct response highlights the importance of protocols in official communication within the NYCDOC framework. A mutual request must be submitted in writing, ensuring there is a clear and documented process for any exchanges between personnel. This formality helps maintain transparency and accountability in operations.

A crucial aspect that invalidates the privilege of sending a mutual request is its connection with a leave of absence. Situations involving leave of absence often require careful consideration of staffing, security, and operational integrity, which may not allow for the flexibility of mutual requests. This ensures that management can allocate resources appropriately and maintain the function of the department without disruption.

The other options do not accurately reflect the conditions under which mutual requests can be processed, either failing to require written communication or relating to scenarios that do not impede the privilege of making such requests.
