What is the correct definition of the term "impairment"?

The term "impairment" is best defined as a condition that leads to diminished functionality. In this context, functioning poorly or incompetently reflects the essence of what impairment implies; it denotes a reduction in the ability to perform tasks or carry out everyday functions effectively. This understanding is particularly relevant in the workplace, where impairment can stem from various factors, including medical conditions, substance use, or psychological issues, leading to challenges in maintaining productivity and effectiveness in one's role.

In contrast, options that describe temporary setbacks or enhancements in productivity do not capture the core meaning of "impairment." While these elements may relate to workplace performance, they do not accurately reflect the fundamental nature of impairment itself, which is characterized by a decrease in competency and the ability to perform effectively.
