When you've been fired, demoted, or denied a promotion after disclosing a disability or requesting accommodations, you know what happened. You can feel it. But proving it in a legal proceeding is a different question entirely.

Courts don't rely on gut feelings. They use a structured framework called the McDonnell Douglas burden-shifting test to evaluate discrimination claims when there's no smoking-gun evidence. Understanding how this framework works tells you what you need to show, what your employer will say in response, and what you'll need to prove next.

What the McDonnell Douglas Framework Is

The McDonnell Douglas test comes from a 1973 Supreme Court case that established a three-stage process for evaluating discrimination claims when the evidence is circumstantial rather than direct. Most disability discrimination cases fall into this category because employers rarely announce they're firing someone for being disabled.

The framework shifts the burden of proof back and forth between the employee and the employer. You prove something first. Then the employer has to respond. Then you get another chance to show their response doesn't hold up. It's not a single moment of proof, but a sequence.

Stage One: The Employee's Prima Facie Case

A prima facie case is the baseline showing that gets you through the door. It doesn't prove discrimination happened: it proves that discrimination could have happened based on the facts you can show.

For a disability discrimination claim under the Americans with Disabilities Act (ADA), you need to establish four elements:

You're a qualified individual with a disability. You have a physical or mental impairment that substantially limits a major life activity, and you can perform the essential functions of your job with or without reasonable accommodation.

Your employer knew about your disability. You disclosed it, you requested accommodations, or it was obvious enough that a reasonable person would have known.

You suffered an adverse employment action. You were fired, demoted, denied a promotion, suspended, or subjected to a significant change in your job duties or pay.

The circumstances suggest a connection. The timing, the stated reasons, or the pattern of treatment suggests your disability was a factor. You were let go two weeks after requesting FMLA leave. You were suddenly written up for performance issues that were never mentioned before. You were told the company was "going in a different direction" right after disclosing your diagnosis.

That's it. You don't need to prove the employer intended to discriminate. You don't need a confession. You need to show these four facts line up in a way that raises the question.

If you can't establish all four elements, the case doesn't proceed. If you can, the burden shifts to the employer.

Stage Two: The Employer's Legitimate Nondiscriminatory Reason

Once you've made your prima facie case, the employer has to respond. They don't have to prove they didn't discriminate, only that they had a legitimate, nondiscriminatory reason for the adverse action.

This is where you'll hear things like:

• "We eliminated the position due to budget cuts."
• "Her performance reviews showed consistent issues with missed deadlines."
• "He violated the attendance policy after multiple warnings."
• "The role required skills she didn't have, and we hired a more qualified candidate."

The employer's burden at this stage is relatively light. They don't have to prove the reason is true or even that it's a good reason. They just have to articulate a reason that, if believed, would be nondiscriminatory.

The stated reason doesn't have to be the only reason. It just has to be a reason unrelated to your disability.

This is why the framework has a third stage.

Stage Three: Proving the Reason Is Pretext

Once the employer offers their reason, the burden shifts back to you. Now you need to show that the stated reason is pretext: a cover story for what really happened.

Pretext doesn't mean the employer is lying outright. It means the reason doesn't hold up under scrutiny. You can show pretext in a few different ways:

The stated reason is factually false. The employer says you were fired for missing deadlines, but your work records show you met every deadline. The performance review they're citing doesn't say what they claim it says. The attendance policy they're enforcing didn't exist until after you requested accommodations.

The stated reason wasn't the real reason. Other employees with the same performance issues weren't disciplined. The "budget cuts" only affected your position, even though others earned more. The employer offered contradictory explanations for the same action at different times.

The stated reason doesn't make sense in context. You were fired for performance issues three days after receiving a positive review. The company hired someone to do your job immediately after claiming the position was eliminated. Your supervisor's emails show they were looking for a reason to terminate you right after you disclosed your disability.

You're not required to prove what the actual reason was: you're proving that the reason they gave you isn't believable. That opens the door for a jury or judge to infer that discrimination was the real cause.

What This Means for Gathering Evidence

The McDonnell Douglas framework is not just a courtroom procedure: it's a lens for evaluating your own situation while you're still employed or shortly after an adverse action.

Document the timeline. When did you disclose your disability or request accommodations? When did the first negative performance review appear? When were you terminated, demoted, or denied a promotion? Timing alone doesn't prove pretext, but a suspicious timeline strengthens your case significantly.

Preserve your performance records. If your employer claims poor performance, you need to be able to show what your actual performance looked like. Save copies of performance reviews, project completions, emails praising your work, and any metrics or evaluations your employer used before the adverse action.

Track how others are treated. If your employer says they fired you for violating a policy, were other employees given warnings first? If they claim budget cuts, were other positions eliminated or just yours? Comparative evidence shows whether the stated reason was applied consistently or selectively.

Save the contradictions. If your supervisor gives you one reason in person, HR gives you a different reason in writing, and the EEOC response letter offers a third explanation, save all of them. Shifting explanations are powerful evidence of pretext.

You can't always know in the moment whether you'll file a charge or pursue legal action. But if you preserve the evidence while it's still available, you'll have what you need if the situation escalates.

How the Framework Plays Out in Practice

Here's a real-world pattern that shows how the stages work:

Prima facie case: You're an accountant with Type 1 diabetes. You requested a modified break schedule to check your blood sugar and eat at consistent times. Two months later, you were terminated for "poor cultural fit." You had no prior disciplinary history, and your last performance review rated you as meeting expectations.

Employer's reason: The company says you were let go because your communication style didn't fit the team's collaborative approach, and other employees complained about your responsiveness.

Pretext showing: No written complaints exist in your file. Your emails show prompt responses to client and internal requests. The "cultural fit" explanation was never mentioned in any prior feedback. Three other employees with similar communication styles were not disciplined. The termination happened within 60 days of your accommodation request, and the stated reason appeared for the first time in the separation letter.

That's how you build a pretext case. You're not arguing that the employer is required to like you or that "cultural fit" can never be a valid reason. You're showing that this specific reason, in this specific case, doesn't add up.

What the Framework Doesn't Do

The McDonnell Douglas test is a tool for organizing proof in cases where the evidence is circumstantial. It doesn't lower the standard for what counts as discrimination, and it doesn't make every adverse action after a disability disclosure into a viable claim.

You still have to show that your disability was a motivating factor in the adverse action. If the employer can demonstrate that the same decision would have been made regardless of your disability, the claim fails even if the stated reason feels thin.

And the framework doesn't prevent employers from articulating reasons that are difficult to disprove. "Cultural fit," "business needs," and "restructuring" are common explanations precisely because they're hard to challenge with objective evidence. That doesn't make them bulletproof, but it does mean you need strong comparative or timeline evidence to show pretext.

Why This Matters for Filing an EEOC Charge

If you're considering filing an EEOC disability discrimination complaint, understanding the burden-shifting framework helps you evaluate whether your charge is likely to survive initial review.

The EEOC investigator will apply this framework when deciding whether to pursue your case, issue a right-to-sue letter, or dismiss the charge. If you can't articulate a prima facie case in your intake questionnaire, the charge may not move forward. If the employer's stated reason is facially plausible and you don't have evidence of pretext, the EEOC may close the file without further investigation.

That doesn't mean you shouldn't file. It means you should be prepared to explain not just what happened, but how the facts fit the legal standard. The clearer your timeline, the stronger your documentation, the more likely your charge will be taken seriously.

When to Talk to an Employment Attorney

The McDonnell Douglas framework is not complicated in theory, but applying it to your own situation requires judgment calls about what counts as pretext and how much evidence is enough. An employment attorney who handles ADA cases can help you assess whether your facts are strong, whether you're missing key evidence, and whether the employer's stated reason is the kind that typically holds up or the kind that falls apart under scrutiny.

If you're still employed and considering requesting accommodations, an attorney can also help you document the request in a way that strengthens your position if the relationship deteriorates later. If you've already been terminated or demoted, consulting an attorney before filing your EEOC charge can make the difference between a charge that gets dismissed at intake and one that leads to a settlement or finding of cause.

The burden-shifting framework gives you a roadmap. It doesn't guarantee an outcome, but it shows you exactly what you need to prove and where the weaknesses in the employer's story might be. That clarity is the first step toward deciding whether to pursue a claim and how to build it.
