Terminations can become more complicated when an employee, during or after offboarding, claims the decision was based on a disability. These claims may involve cognitive conditions, such as autism or ADHD, or physical conditions, such as chronic pain or medical disorders. While these situations can feel high-risk, the legal framework for evaluating them is consistent and manageable when employers follow sound practices.

Under the Americans with Disabilities Act (ADA), employers may not discriminate against qualified individuals based on a disability. However, the law does not prevent employers from terminating an employee for legitimate, job-related performance or conduct reasons. The critical factors are whether the employer knew about the disability at the time of termination, whether an accommodation was requested, and whether the termination decision was based on documented performance concerns.

Cognitive disability claims raised after termination are increasingly common. For example, an employee terminated during training for failing to complete assignments, refusing to follow training protocols, or questioning supervisory authority may later state that the termination was due to autism or another neurodivergent condition. If the employee never disclosed the condition or requested accommodations prior to termination, the employer generally had no obligation to initiate the ADA interactive process. Employers are not required to speculate about undisclosed conditions, and a performance-based termination made without knowledge of a disability is typically defensible.

Physical disability claims raised after termination are evaluated using the same principles. For instance, an employee may assert after termination that a chronic back condition, migraines, or diabetes affected their performance. If the condition was not disclosed and no accommodation was requested before termination, employers are not expected to retroactively adjust decisions that were based on documented performance or training failures. Again, the absence of prior knowledge is significant.

In both cognitive and physical disability scenarios, documentation is essential. Employers should ensure that performance issues are clearly recorded, tied to essential job functions, and consistent with the reason communicated at termination.  Documentation should include a timeline showing when issues occurred. 

When an employee raises a disability claim during offboarding, employers should avoid debating or attempting to disprove the condition. A neutral response acknowledging the statement while reiterating that the decision was based on performance is best practice. Any follow-up communications, especially those involving legal threats or agency complaints, should be routed through HR or legal counsel.

Employers can reduce future risk by training managers to recognize when a disclosure or accommodation request may be occurring and to involve HR early. Clear processes, consistent documentation, and measured responses allow employers to handle post-termination disability claims whether cognitive or physical fairly, lawfully, and confidently.
