Why Managers Should Never Diagnose Employees

Managers often inadvertently create legal liability by attempting to diagnose employees with conditions like ADHD based on performance issues. This practice, while frequently rooted in empathy, shifts the focus away from objective performance standards and creates significant discrimination risk. Effective HR intervention requires pivoting the conversation back to documented performance and specific skill gaps rather than medical speculation. Managers should be coached to avoid informal, unrecorded accommodations, which lead to inconsistent expectations and future conflict. Instead, HR must guide leaders through the formal interactive process, ensuring that support is provided through established, compliant channels. By treating these scenarios as opportunities for manager education and development, HR professionals can resolve performance issues while protecting the organization and fostering a professional environment that respects both employee privacy and legal requirements.
