Final answer:
Jefferson is a motivational speaker, using his communication skills to encourage employees, much like Dr. Martin Luther King, Jr. did during the civil rights movement.
Step-by-step explanation:
Jefferson, as a human relations department employee working on encouraging and influencing employees toward a common goal, is a motivational speaker. Similar to how Dr. Martin Luther King, Jr. used his public speaking abilities to inspire and lead African Americans during the civil rights movement, Jefferson uses his communication skills to motivate his colleagues. Motivational speakers play a crucial role in guiding and uplifting others, often by providing clear objectives, instilling confidence, and fostering a collaborative environment.
