Common ADA Mistakes Employees Make Without Training

2/6/2026

An organization can have the most meticulously crafted policies on the Americans with Disabilities Act (ADA), but those policies are only as effective as the employees who implement them. A single untrained manager or HR team member can unknowingly commit a costly violation, exposing the entire company to legal action. ADA-related lawsuits rarely stem from a deliberate desire to discriminate; they are most often the consequence of simple, preventable mistakes made by well-intentioned people who just don't know the rules.

This lack of knowledge creates a significant, often hidden, liability within an organization. When employees are not equipped with formal ADA compliance training, they are forced to rely on assumptions, outdated information, or gut feelings when faced with a disability-related issue. This guesswork is a recipe for disaster, leading to a host of common errors that can have severe financial and reputational consequences.

This article will detail the most frequent and damaging ADA mistakes that employees make without proper training. We will explore how these errors occur in the real world and demonstrate how targeted education is the most powerful tool for preventing them, turning a major source of risk into a well-managed compliance function.

Mistake 1: Failing to Recognize an Accommodation Request

This is perhaps the most common and fundamental error made by untrained employees, particularly frontline managers. It is the first domino in a chain reaction that often leads to a lawsuit.

What the Mistake Looks Like

An employee does not need to use the words “reasonable accommodation” or “ADA” to trigger an employer's legal obligations. Many untrained managers believe they can ignore a disability-related issue until an employee submits a formal, written request to HR. This is incorrect and dangerous.

A request can be a simple, verbal statement about a workplace challenge related to a medical condition.

• An employee tells their supervisor, "My new medication makes it hard to focus in our noisy open-plan office."
• A retail worker mentions, "Standing for my entire shift is becoming really painful for my back."
• A remote employee says, "I'm getting terrible headaches from staring at this small laptop screen all day."

An untrained manager might hear these as complaints, excuses, or personal problems. They might respond with unhelpful advice like "try to focus better," "everyone's back hurts," or "maybe you should get a bigger monitor at home." By doing so, they have failed to recognize a legal request for help and have broken the first link in the compliance chain.

How Training Prevents This Mistake

ADA training for managers is laser-focused on this single point of failure. The training drills into managers that their job is not to solve, judge, or investigate, but to spot and report. They learn to identify these trigger phrases and understand that any mention of a medical condition impacting work is a signal to escalate the matter to HR immediately. This transforms managers from a potential liability into the company's first line of defense.

Mistake 2: Asking Illegal or Improper Questions

When faced with a disclosure about a medical condition, an untrained employee's natural curiosity can lead them down a legally perilous path.

What the Mistake Looks Like

Upon hearing about an employee's medical issue, an untrained manager or even an inexperienced HR person might start asking for details they are not legally entitled to know.

• "What's your diagnosis? What's wrong with you?"
• "Are you sure you can't just work through it? You don't look sick."
• "Who is your doctor? What did they say?"

These questions represent a significant overstep. The ADA has strict rules about medical inquiries. An employer’s right to medical information is limited to what is necessary to understand the employee’s functional limitations and the need for an accommodation. A diagnosis is almost never required.

How Training Prevents This Mistake

A comprehensive ADA certification program provides HR professionals with a clear understanding of the legal boundaries surrounding medical inquiries. They learn to draft legally compliant requests for medical information that focus solely on work-related limitations. Managers are trained on a "do not ask" list, learning to respond with empathy ("Thank you for telling me") and then pivot to the proper channel ("Let's connect you with HR, who is trained to handle these confidential matters").

Mistake 3: A "One-and-Done" Approach to the Interactive Process

The ADA accommodation process is not a single event; it is an ongoing, good-faith dialogue. Untrained employees often treat it as a simple transaction, which is a critical misunderstanding.

What the Mistake Looks Like

An employee requests an accommodation. The HR person offers one solution. The employee says it won't work. The HR person, believing they have fulfilled their duty, ends the conversation and closes the file.

Another common error is an unreasonable delay. The request is received, but weeks or even months go by with no action or communication, leaving the employee in limbo. Both scenarios demonstrate a failure to engage in the "interactive process" in good faith, which is a violation in itself.

How Training Prevents This Mistake

AnADA Training & Certification Program teaches that the interactive process is a collaborative, problem-solving conversation. HR professionals learn to:

• Brainstorm multiple accommodation options.
• Explain why a requested accommodation might pose an "undue hardship" and then work to find an alternative.
• Document every conversation, meeting, and decision to create a clear record of their good-faith efforts.
• Follow up after an accommodation is implemented to ensure it is effective.

This structured, documented approach is the hallmark of a compliant process and is often detailed in a course'sAgenda/Table Of Contents/Course Outline.

Mistake 4: Unintentional Retaliation

Retaliation claims are one of the most common and dangerous legal risks under the ADA. They often happen when a manager feels frustrated by an employee's accommodation or leave.

What the Mistake Looks Like

An employee is granted intermittent leave as an accommodation for a chronic illness. Their manager, annoyed by the unpredictable absences, starts scrutinizing their work more closely than other team members. The employee is then written up for minor errors that were previously overlooked.

Another example: An employee returns from disability leave, and their manager gives them a poor performance review that penalizes them for lower output during their medically-approved absence. Even if the manager's frustration is understandable from an operational standpoint, these actions are likely illegal retaliation.

How Training Prevents This Mistake

Training provides managers with a clear understanding of what constitutes retaliation. They learn that any adverse action—from a formal write-up to being excluded from a project—taken shortly after a protected activity can form the basis of a retaliation claim. They are taught to focus on legitimate performance issues and apply standards consistently across their entire team, while ensuring they do not penalize employees for the direct impact of their disability or accommodation.

Mistake 5: Ignoring Digital Accessibility

In today's workplace, especially with the rise of hybrid and remote work, digital tools are essential. Untrained employees often fail to consider whether these tools are accessible.

What the Mistake Looks Like

• An IT department purchases and rolls out a new project management software without verifying if it is compatible with screen readers, effectively locking out employees with visual impairments.
• A manager shares a critical update in a team meeting via a complex chart on a slide but doesn't verbally describe the chart, leaving visually impaired employees out of the loop.
• A company hosts a mandatory all-hands webinar but fails to provide live captioning, creating a barrier for employees who are deaf or hard of hearing.

These are not minor inconveniences; they are direct violations of ADA workplace requirements for the modern era.

How Training Prevents This Mistake

Specialized training on ADA compliance for remote teams and digital workplaces addresses these issues head-on.

• IT and procurement teams learn to make accessibility a key criterion in their purchasing process, using tools like an ADA compliance checklist.
• Managers and content creators are taught the basics of creating accessible documents and running inclusive virtual meetings.
• HR professionals learn how to manage accommodations related to technology, ensuring all employees have equal access to the tools needed for their job.

Mistake 6: Mishandling the End of FMLA Leave

This is a classic and costly mistake. An untrained HR employee sees that an employee's 12 weeks of FMLA leave are exhausted and, if the employee is not ready to return, proceeds with termination.

What the Mistake Looks Like

An employee takes 12 weeks of FMLA leave for back surgery. At the end of the 12 weeks, their doctor states they need two more weeks of recovery before they can return. The HR department, following a rigid FMLA policy, terminates the employee's employment. This single action has just created a near-certain wrongful termination lawsuit under the ADA.

How Training Prevents This Mistake

Advanced training, particularly aCertificate Program In FMLA & ADA Compliance, teaches HR professionals that the end of FMLA leave is often the beginning of an ADA obligation. They learn that a finite period of additional leave is a form of reasonable accommodation that must be considered. A trained professional automatically triggers the ADA interactive process the moment they know an employee returning from FMLA may have continued restrictions, thus avoiding this massive legal landmine.

Conclusion: Education is the Only Antidote

The common ADA mistakes made by untrained employees are not just procedural errors; they are actions with profound human and financial consequences. They can lead to the loss of a valued employee, costly legal battles, and damage to a company's reputation as a fair and inclusive employer.
