The Americans with Disabilities Act (ADA) is one of the most powerful workplace protections in federal law — and one of the most frequently violated. Employers fire, demote, and refuse to accommodate disabled employees every day, often while claiming the decision was about "performance" or "business needs." This guide explains what the ADA actually requires and what to do if your employer has violated it.
The ADA applies to employers with 15 or more employees. It prohibits discrimination against a "qualified individual with a disability" in any aspect of employment — hiring, firing, pay, promotions, job assignments, training, and any other term or condition of employment.
A "disability" under the ADA is defined broadly: a physical or mental impairment that substantially limits one or more major life activities, a record of such an impairment, or being regarded as having such an impairment. After the ADA Amendments Act of 2008, courts interpret "disability" expansively. Conditions that routinely qualify include:
You don't need to be severely disabled to be protected. If your condition substantially limits a major life activity — walking, seeing, hearing, sleeping, concentrating, communicating, or caring for yourself — you likely qualify.
Employers are required to provide "reasonable accommodations" — modifications to the work environment or how a job is performed — that allow a qualified employee with a disability to do their job. The accommodation process is supposed to be an interactive dialogue between the employee and employer. Neither side can simply refuse to engage.
You don't need to use the words "reasonable accommodation" or cite the ADA to trigger this obligation. Telling your employer that you have a medical condition and need a change in your work situation is enough. Once you make that request, the employer must respond — it cannot simply ignore you.
An employer can only deny an accommodation if it would cause "undue hardship" — significant difficulty or expense given the size and resources of the business. This is a high bar. Courts rarely find undue hardship for large employers. An employer cannot simply say an accommodation is inconvenient or that it prefers not to make changes.
If an employer claims undue hardship, it must consider whether there are alternative accommodations that would work. The obligation is to find an effective accommodation — not necessarily the specific one the employee requested.
Firing an employee because of their disability — or because they requested an accommodation — is illegal. So is retaliating against an employee for filing an ADA complaint, participating in an investigation, or opposing discriminatory practices.
Employers rarely say "we're firing you because of your disability." Instead, they cite performance issues, restructuring, or budget cuts. The key is to look at the pattern and timing. Warning signs that a termination may be disability-related include:
When an employee requests an accommodation, the employer must engage in a good-faith interactive process to identify an effective solution. This means:
A breakdown in the interactive process caused by the employer — ignoring requests, delaying indefinitely, refusing to consider alternatives — is itself an ADA violation, even if the employer never formally denies the accommodation.
