Testing conducted for an employee exhibiting erratic behavior is best described as a reasonable suspicion or for cause test. This type of test is implemented when there are observable signs or documented behaviors that suggest a potential impairment, which can seriously affect safety and performance in the workplace. Erratic behavior could indicate substance abuse or other issues that may compromise an employee's ability to perform their job safely and effectively.

The reasonable suspicion test allows employers to act based on specific and objective observations rather than random selections or general screening processes. This ensures that testing is appropriate and justified based on the employee's behavior, protecting both the employee's rights and the safety of the workplace.

In contrast, routine compliance tests are typically conducted systematically and on a predetermined schedule, unrelated to any specific behaviors. Random drug screenings are unannounced tests conducted without prior suspicion, while periodic health assessments generally monitor the overall health of employees but do not focus on the immediate and specific concerns raised by erratic behavior. Therefore, the correct approach in response to behavior that raises concerns about an employee’s fitness for duty is to conduct a reasonable suspicion or for cause test.
