Final answer:
Alisha is displaying arrogance, identified by her overconfidence that makes her unapproachable to employees, indicating a sense of superiority or inflated self-image.
Step-by-step explanation:
If Alisha appears to be overconfident and unapproachable to her employees, the negative quality she is displaying would best be described as arrogance. This is because overconfidence at the point of being unapproachable suggests a sense of superiority or an inflated self-image, which aligns with the concept of arrogance. It is important for leaders to be aware of how their behavior affects those around them to maintain a positive work environment.
