Which of the following is a common sign of impairment in the workplace?

The common sign of impairment in the workplace is excessive use of sick time. When an employee frequently calls in sick without a clear medical reason, it may indicate underlying issues that could be related to impairment. Such patterns can arise from various factors, including substance abuse, mental health challenges, or other personal issues that impact an individual's ability to function effectively in their job. Recognizing this behavior is crucial, as it can prompt further investigation and support for the employee, ultimately enhancing workplace safety and productivity.

In contrast, participation in team-building activities, regular attendance at work, and timely completion of tasks are indications of a productive and engaged employee. These behaviors generally reflect a positive work ethic and responsibility, which are not associated with impairment.
