What is an indicator of an individual being unfit for duty?

Possession of illegal drugs or alcohol is a significant indicator of an individual being unfit for duty because it can impair judgment, coordination, and responsiveness, which are critical for maintaining safety and professionalism in the workplace. The use of these substances can affect an individual's ability to perform tasks effectively and can lead to dangerous situations, both for the individual and their coworkers.

In contrast, active participation in projects, high morale among coworkers, and regular attendance at work are positive indicators of an employee’s engagement and commitment to their role. Such behaviors suggest that the individual is likely performing competently and maintaining a suitable state of mental and physical readiness for their responsibilities.
