Even With Accommodations, Essential Functions Are Required Under ADA

Why It Matters

Employers must clearly define essential functions and engage in good‑faith interactive processes, or risk liability when employees cannot meet core job requirements. The rulings also clarify that failure to perform essential duties, not just lack of accommodation, defeats ADA protection.

Key Takeaways

• Define essential functions in written job descriptions
• Employers bear burden to prove essential duties are core
• Interactive process must be collaborative; employee non‑participation harms claim
• Reasonable accommodations cannot create new essential duties
• ADA retaliation protections apply regardless of qualified status

Pulse Analysis

The Fourth Circuit’s recent opinions sharpen the legal line between accommodation and qualification under the Americans with Disabilities Act. Courts will scrutinize whether an employer’s identified essential functions truly reflect the core of the position, requiring documentation such as detailed job descriptions and senior staff testimony. When an employee’s medical limitations prevent performance of those core duties—even after reasonable adjustments—the ADA’s "qualified individual" shield disappears, leaving the employer free to terminate without discrimination liability.

For HR leaders, the rulings serve as a practical checklist. First, codify essential functions in writing and distribute them to incumbents, ensuring each duty bears more than a marginal relationship to the role. Second, conduct the interactive process in good faith, exploring all feasible accommodations while documenting communications. If an employee reneges on agreed‑upon accommodations or fails to engage, the employer gains a robust defense. Conversely, any breakdown caused by the employer can revive liability, emphasizing the need for meticulous record‑keeping.

Beyond compliance, the decisions highlight strategic risk management. Employers can exceed statutory obligations—such as offering hybrid schedules or reassigning tasks—without incurring liability, provided they can demonstrate that no reasonable accommodation would enable the employee to perform essential functions. However, they must remain vigilant about the ADA’s anti‑retaliation provisions, which protect employees regardless of qualification status. By aligning policies with these precedents, organizations safeguard against costly litigation while fostering an inclusive workplace culture.
