Employers often give a reason for a workplace decision, such as performance, attendance, conduct, staffing, policy, or business needs. A stated reason does not by itself decide whether a decision was lawful, and a disagreement with the reason does not by itself establish discrimination or retaliation. In an employment matter, the relevant legal theory, the decision, the employer’s coverage, the applicable forum, and the facts all matter. This page provides general federal information as of September 16, 2026, not legal advice about a particular workplace action.
Performance decisions and federal disability law
Title I of the Americans with Disabilities Act (ADA) generally prohibits covered entities from discriminating against a qualified individual on the basis of disability in job applications, hiring, discharge, compensation, training, and other terms, conditions, and privileges of employment. It also addresses certain contractual or other relationships that have the effect of subjecting an applicant or employee to prohibited discrimination.
The ADA does not prevent every performance, conduct, attendance, restructuring, or termination decision involving a person with a medical condition. A federal analysis can involve whether the person is covered by the statute, whether the person is qualified, the nature of the decision, an employer’s stated reason, and the applicable legal theory. Those questions are not identical in every case.
Three distinct ADA-related questions
Disability discrimination, reasonable accommodation, and retaliation are related but distinct concepts. A discrimination question may concern an action allegedly taken because of disability. A reasonable-accommodation question may involve known limitations and the statute’s conditions and exceptions. A retaliation or interference question may concern protected opposition, participation, coercion, intimidation, threats, or interference. A reader should not assume that the same facts establish each theory or that a conclusion about one resolves another.
Current statutory and regulatory text includes 42 U.S.C. § 12112, 29 C.F.R. § 1630.9, and 42 U.S.C. § 12203.
Why the stated reason may be examined in context
An employer may identify a legitimate, nondiscriminatory, or nonretaliatory reason for an action. In a particular matter, the parties may dispute whether that explanation is supported, consistently applied, connected to the actual decision, or affected by other facts. The applicable evidentiary standards and burdens can vary by claim, court, and procedural posture.
For example, the timing of a performance write-up, differences between explanations, treatment of comparable situations, or a conflict between an explanation and other information can be relevant in some matters. None of those circumstances is automatic proof that a decision was discriminatory or retaliatory. A proper analysis depends on the whole record and the law that governs the particular claim.
What the Burton case illustrates—and does not
A 2015 Fifth Circuit decision, Burton v. Freescale Semiconductor, Inc., involved a temporary worker’s ADA claim, questions about the relationship between a staffing company and a worksite company, and competing explanations for ending the assignment. The court’s decision addressed the record before it at the summary-judgment stage. It is not a nationwide checklist for every performance-related workplace dispute, and it does not establish that later documentation, an inconsistent explanation, or a staffing arrangement automatically determines a claim.
The example is useful only for the limited proposition that courts may evaluate the factual support and timing of stated reasons in the context of the specific legal theory and record before them. It does not predict what will occur in another case.
Coverage and worker relationships can vary
The ADA’s definitions include employer, employment agency, labor organization, and joint labor-management committee, but coverage and relationships are evaluated under statutory and regulatory definitions. Staffing, contract, assignment, and workplace-control arrangements can raise fact-specific questions. A label such as “temporary,” “contractor,” “manager,” or “vendor” does not independently answer every employment-law question.
Agency process and timing
For employment-discrimination matters within EEOC jurisdiction, the agency provides current information about how to file a charge, time limits, and what to expect after filing. Requirements can vary by employer, location, claim, and process. This page does not establish a universal deadline, filing requirement, proof standard, or remedy.
What this guide does not decide
This guide does not decide whether a stated performance or conduct reason was accurate, consistently applied, discriminatory, retaliatory, or legally sufficient. It does not decide worker status, coverage, accommodation, protected activity, a filing route, a deadline, a remedy, or an outcome. It does not request diagnoses, medical records, internal files, protected complaints, or other sensitive information.
