Which of the following unions does NOT serve licensed officers?

The correct answer pertains to the Seafarers International Union, which typically does not represent licensed officers. Instead, it primarily includes unlicensed ratings and less specialized maritime personnel.

On the other hand, the other unions listed—AMO (American Maritime Officers), MMP (Marine Engineers' Beneficial Association), and MEBA (Marine Engineers' Beneficial Association)—are focused on representing licensed officers. AMO and MEBA specifically provide support for licensed engineers and officers, while MMP represents licensed maritime personnel as well. These unions are tailored to address the needs, benefits, and rights of those who hold maritime licenses, including captains and other management-level positions, making them critical for licensed officers in safeguarding their interests at sea. Thus, recognizing the specific focus of each organization helps clarify why one union stands apart as not serving licensed officers.
