Q: One of our employees has been exhibiting strange, erratic behavior at work. Can we require the employee to submit to a mental health examination?

A: Possibly. The ADA prohibits employers from requiring their workers to undergo medical exams unless the exam is “shown to be job-related and consistent with business necessity.” However, an employer may require an employee to undergo a mental health examination if the employee’s behavior raises questions about the employee’s ability to perform essential job-related functions or raises a safety concern.
