Which of the following is a mental limitation that can lead to impairment?

Chronic stress is recognized as a mental limitation that can significantly lead to impairment in the workplace. When an individual experiences ongoing stress, it can affect their cognitive functions, emotional health, and overall well-being. Chronic stress may lead to difficulties in concentrating, making decisions, and managing time effectively, which can ultimately impair job performance and efficiency. This condition can also manifest physically, leading to health problems that may further exacerbate mental impairment.

In contrast, while lack of physical fitness, low employee morale, and unclear job descriptions can impact employee performance, they do not directly represent a mental limitation. Lack of physical fitness pertains more to physical health rather than mental capacity, low employee morale reflects an emotional or psychological state but is not a direct mental limitation, and unclear job descriptions can lead to confusion but do not inherently affect an individual's mental capacities in the same way that chronic stress does. Thus, chronic stress stands out as the option that aligns most closely with mental impairment.
