Which of the following is a sign of impairment in job performance?

Excessive use of sick time can be a significant indicator of impairment in job performance. When an employee frequently takes sick leave without valid medical reasons, it may suggest underlying issues affecting their ability to perform their job duties effectively. This behavior could stem from physical or mental health problems, substance abuse, or personal challenges that impact their work attendance and productivity.

In contrast, consistently high performance ratings, a willingness to take on extra duties, and frequent attendance at work events typically suggest that an employee is engaged and performing well in their role. While these behaviors could contribute to a positive work environment, they are not indicative of impairment.
