Job Restructuring as an ADA Reasonable Accommodation

Under the Americans with Disabilities Act, job restructuring is a recognized reasonable accommodation, and the most common form is removing or reassigning the marginal tasks a disability keeps you from performing. Federal regulations list job restructuring by name among the accommodations a covered employer may need to provide.¹ The line that decides everything is between essential functions, the core duties the job exists to perform, and marginal functions, the secondary tasks that can be shifted to someone else. Only marginal functions are on the table.

Which Employers Have to Do This

The ADA’s employment rules apply to employers with 15 or more employees for at least 20 calendar weeks in the current or preceding year.² Below that threshold, federal ADA protections don’t reach you, though many states have their own disability laws that cover smaller workplaces. For covered employers, failing to accommodate the known limitations of a qualified employee with a disability is itself discrimination under the statute.³

How to Ask

You don’t need to say “reasonable accommodation” or cite the ADA. EEOC guidance says the request only has to communicate that you need a change at work because of a medical condition.⁴ “My back condition makes the lifting part of this job hard” is enough. Verbal is legally sufficient. Written is smarter, because it creates a record.

Once you ask, the employer is supposed to start what the regulations call an “informal, interactive process” to figure out what will work.¹ In practice, that’s a conversation: you describe the limitation, the employer explores options. You don’t have to propose the solution, but you do have to explain the problem. If your employer ignores the request or refuses to engage, that failure alone can create liability.⁵

What Counts as Marginal

Everything hinges on this classification. Essential functions are the fundamental duties the position exists to perform; marginal functions are everything else.⁶ Only marginal ones can be removed or reassigned. The regulation lists several kinds of evidence relevant to sorting a task into one category or the other:

How much of the workweek the duty actually consumes. A task that eats a small fraction of hours is more likely marginal.
What happens if it isn’t done. If nobody notices and output doesn’t drop, the task probably isn’t essential.
The employer’s own judgment, especially when documented in advance of hiring.
Written job descriptions prepared before recruiting, which carry weight but aren’t the final word.
Collective bargaining agreements that assign duties to particular positions.
What people currently and previously in the role actually do day to day.

These come straight from the regulation.⁶ No single factor decides. If an employer insists that filing quarterly reports is essential, but the last three people in the job never filed them and accounting always handled it, the label doesn’t hold.

Two workplace realities push heavily on the analysis. First, how many people are around to absorb the task. A large team with overlapping duties can shift a minor responsibility with no real disruption; a three-person office has nowhere to put it. Second, the expertise the task requires. A duty that needs a specific license or specialized training is harder to call marginal even if it’s rarely performed, because there may be no one else who can do it.

How the Reassignment Plays Out

Once both sides agree a duty is marginal and your disability prevents you from doing it, the employer removes it from your responsibilities and typically hands it to someone else. The regulations define reasonable accommodation to include adjustments to how a position is customarily performed so a qualified individual with a disability can handle the essential functions.¹ Most workplaces handle this as a swap: you pick up an administrative duty from a colleague who takes on the physical task you can no longer do. Updated job descriptions or work plans should reflect the change so expectations are clear.

Essential Functions Are Off the Table

Job restructuring has a firm limit. Employers are never required to eliminate an essential function. The ADA defines a “qualified individual” as someone who can perform the essential functions of the job, with or without reasonable accommodation.² A delivery driver who can’t drive can’t ask the employer to remove driving from the job.

Courts generally defer to an employer’s judgment about which functions are essential, provided the judgment is backed by evidence. A written job description prepared before hiring carries particular weight.² But that deference has limits. If a function is labeled essential on paper and nobody in the role ever performs it, the label won’t survive scrutiny. What the job actually entails matters more than what the description aspires to.

Production Standards Don’t Get Lowered

A related point that often confuses people: employers don’t have to lower production or performance standards as an accommodation. If your role requires processing 50 applications per day, the employer can keep that number after restructuring your duties. EEOC guidance is clear that dropping a production standard because a disability prevents an employee from meeting it isn’t a reasonable accommodation.⁷ What can change is how you meet the standard. Assistive technology, schedule modifications, and stripping out marginal duties that eat your time can all help you hit the same numbers by a different route.

Medical Documentation

If your disability and your need for the accommodation are both obvious, the employer can’t demand medical paperwork. When either isn’t apparent, the employer can ask for reasonable documentation from a healthcare provider.⁵

The request has to stay narrow. Documentation is limited to what establishes you have an ADA-covered disability and that it creates a need for the specific accommodation you’re seeking. Your complete medical file is off-limits, since it will contain material unrelated to the question at hand. If you have multiple disabilities, only the relevant one is fair game.⁵ The trade-off runs both ways: if your disability isn’t obvious and you refuse to provide any documentation when asked, you forfeit the accommodation.

When the Employer Can Refuse

Undue Hardship

Even a clearly marginal task can stay put if reallocating it would cause undue hardship, which the ADA defines as significant difficulty or expense.² The assessment looks at the specific employer, not a generic yardstick. The EEOC weighs the cost of the accommodation and its broader financial impact on the facility, the facility’s own resources and headcount, the overall resources of a parent company if one exists, and whether the accommodation would be unduly disruptive or fundamentally alter how the business operates.⁵

For restructuring specifically, undue hardship is a harder win for employers than it is with high-cost accommodations, because shifting a task to a coworker usually costs nothing. The stronger employer argument tends to be operational disruption, and it’s strongest in small workplaces with no one available to absorb the work.

Seniority Systems and Union Contracts

Reallocating duties gets complicated where a seniority system or collective bargaining agreement is in play. In US Airways, Inc. v. Barnett, the Supreme Court held that an accommodation conflicting with seniority rules is ordinarily unreasonable, though an employee can still prevail by showing special circumstances that would justify an exception.⁸ The EEOC applies the principle to both union-negotiated and management-imposed systems. Special circumstances might exist where the employer has frequently altered seniority rules or where the system already contains built-in exceptions, so that one more exception wouldn’t undermine what the system was designed to protect.⁵

When Restructuring Isn’t Enough

Sometimes stripping out marginal tasks still leaves essential functions the employee can’t perform. At that point, the employer must consider reassignment to a vacant position for which the employee is qualified. The ADA lists reassignment as a form of reasonable accommodation, but it’s treated as a last resort, after options for keeping you in your current role are exhausted. A position counts as vacant if it’s open when you request the accommodation or if the employer knows it will open within a reasonable timeframe. The employer doesn’t have to displace another worker or invent a new role.⁵

Retaliation and Filing Deadlines

Federal law prohibits retaliation for requesting an accommodation. The ADA bars discrimination against anyone who opposes unlawful practices or participates in a proceeding under the statute, and it also prohibits coercion, intimidation, and interference with the exercise of these rights.⁹ Negative reviews, reduced hours, or a suddenly hostile environment appearing after your request can constitute retaliation even when the employer offers a different explanation.

If your employer denies restructuring without engaging in the interactive process, or denies it on grounds that don’t hold up (like calling a rarely performed task essential), you can file a charge with the EEOC. The deadline is 180 days from the discriminatory act, extended to 300 days where a state or local anti-discrimination law also covers the complaint.¹⁰ Missing that window generally forfeits the federal claim regardless of its merits. Document your initial request, the employer’s responses, any medical information you provided, and evidence of how the disputed tasks are actually handled. An employer that participated in the interactive process in good faith has stronger footing against punitive damages; an employer that refused to engage at all makes your case stronger.⁵
