What is the greatest risk Aplomb faces regarding Percy’s situation?

The situation with Percy poses the greatest risk to Aplomb primarily due to the concept of employee derailment. Derailment refers to when a potentially high-performing employee experiences obstacles that significantly hinder their performance or career progression, often leading to negative outcomes for both the employee and the organization. If Percy is experiencing derailment, it could reflect problems such as lack of engagement, poor performance, or misalignment with job responsibilities.

This can have a cascading effect on team morale, productivity, and overall department effectiveness. Aplomb’s focus should be on addressing Percy’s situation to prevent further decline in his performance, which could affect not just Percy but also the performance of the team as a whole.

Addressing the other concerns could be important as well, but Percy's derailment indicates a direct and immediate problem that can impact not only Percy’s career but also the performance and stability of the entire work environment. It's crucial for Aplomb to intervene to prevent long-term damage caused by this risk, making it the most pressing issue at hand.
