An employer generally does not have to create a light duty position that doesn’t already exist, but the question of whether an employer has to offer light duty work is more layered than a flat yes or no. The Americans with Disabilities Act can require reassignment to a vacant modified position as a reasonable accommodation. Workers’ compensation systems in every state push employers toward offering modified assignments to injured workers, even without strictly mandating it. And once an employer runs a light duty program, the ADA restricts how narrowly it can define who qualifies.
The Short Answer: Create vs. Offer
Federal law draws a clear line between inventing a new job and offering one that already exists. Courts have been consistent that the ADA does not require an employer to build a brand-new light duty position for an injured or disabled worker. What the ADA does require is that when a vacant position exists that fits the employee’s restrictions, the employer must consider reassigning the employee to it as a form of reasonable accommodation.1Office of the Law Revision Counsel. 42 USC 12111 Definitions
That distinction drives almost every dispute in this area. An employer can say no to creating something new. An employer generally cannot say no to using what it already has.
When the ADA Requires an Employer to Offer Light Duty
The ADA applies to employers with fifteen or more employees and prohibits discrimination against qualified individuals with disabilities. Failing to make a reasonable accommodation for a known physical or mental limitation is itself a form of prohibited discrimination, unless the accommodation would impose an undue hardship on the business.2Office of the Law Revision Counsel. 42 U.S. Code 12112 – Discrimination The statute lists job restructuring, modified work schedules, and reassignment to a vacant position as examples of reasonable accommodation.1Office of the Law Revision Counsel. 42 USC 12111 Definitions Light duty assignments fit within all three of those categories.
Existing Light Duty Pools Cannot Be Walled Off
This is where employers most often stumble. If an employer maintains a set of light duty positions reserved for workers’ compensation injuries, the ADA requires the employer to consider reassigning an employee with a non-work-related disability into a vacant reserved slot as a reasonable accommodation.3U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Workers’ Compensation and the ADA
The EEOC gives a concrete example. An assembly line worker develops multiple sclerosis and can no longer perform her regular job. Her employer has a vacant light duty position that it normally reserves for on-the-job injuries. Refusing to reassign her to that position violates the ADA. The employer cannot establish undue hardship simply by arguing it might need those slots for future workers’ comp cases.3U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Workers’ Compensation and the ADA
The Interactive Process Is Not Optional
Before an employer can conclude that no accommodation is possible, it has to engage with the employee to figure out what might work. The EEOC calls this the interactive process, and its regulatory basis sits in 29 CFR 1630.2(o)(3).4U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship Under the ADA In practical terms, the employer asks about the employee’s limitations, reviews medical documentation, and explores potential modifications. The employee’s input matters. Employers who deny requests outright, or who go through the motions without genuinely considering alternatives, expose themselves to liability.
Undue Hardship Is a Real but Narrow Defense
An employer can refuse a requested accommodation if it would cause significant difficulty or expense. The statute weighs the cost of the accommodation, the employer’s financial resources and size, the number and type of facilities, and the operational impact.1Office of the Law Revision Counsel. 42 USC 12111 Definitions A small business with thin margins has a stronger argument than a national employer. The burden sits with the employer, and general claims about inconvenience will not carry it.
Workers’ Compensation and the Push Toward Light Duty
Workers’ compensation systems in every state encourage employers to bring injured workers back on modified assignments. The incentive structure is financial rather than mandatory in the ADA sense: when an injured employee returns to any productive work, wage-replacement claims shrink, insurance premiums stabilize, and claim durations shorten. Employers who ignore the option often pay for it through their workers’ comp costs.
For the employee, accepting light duty usually preserves income. If the modified assignment pays less than the pre-injury role, most states provide Temporary Partial Disability benefits that cover part of the gap, subject to state-specific formulas and maximums. Whether an employee qualifies depends on the state workers’ comp statute and the specifics of the wage reduction.
Workers’ compensation doesn’t itself force an employer to invent a light duty role. What it does is make the offer attractive enough that most employers with any available modified work will make one.
Work-Related vs. Non-Work-Related Injuries
The source of the injury changes which laws apply. Workers’ compensation covers only injuries and illnesses that arise out of employment. The ADA covers qualified individuals with disabilities regardless of how the disability arose. The FMLA covers serious health conditions no matter the cause.
The practical consequence is that an employer who runs a light duty program limited to on-the-job injuries cannot lawfully turn away an employee with a non-work-related disability who needs the same kind of modified assignment. The ADA still requires the employer to consider reassignment to a vacant light duty position, even one the employer normally treats as reserved for workers’ comp cases.3U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Workers’ Compensation and the ADA Sorting employees by how they got hurt, without a legitimate operational reason, creates ADA exposure.
What Happens If the Employer Won’t Offer Light Duty
An employee who wants modified work but doesn’t get it has options depending on the circumstances.
If the employee has a covered disability and the employer runs an existing light duty pool or has a vacant position that fits the restrictions, the refusal may be an ADA violation. The EEOC accepts charges of discrimination, and an employment attorney can evaluate whether a reasonable accommodation was denied without adequate justification.
If the employee is FMLA-eligible and has a serious health condition, they can take up to twelve weeks of unpaid, job-protected leave whether or not light duty is available.5eCFR. 29 CFR 825.702 – Interaction With Federal and State Anti-Discrimination Laws FMLA leave is a floor of job protection that runs alongside whatever the workers’ comp and ADA analyses produce.
The Flip Side: Refusing an Offer
The obligation runs in both directions. If the employer does offer suitable light duty and the employee turns it down, workers’ comp wage-replacement benefits can be reduced or suspended in most states. The offered work generally must align with the employee’s documented medical restrictions to count as suitable; an assignment that exceeds the physician’s limits gives the employee grounds to refuse without losing benefits.
An FMLA-eligible employee has an additional layer of protection. The employer cannot force acceptance of light duty as a substitute for FMLA leave.5eCFR. 29 CFR 825.702 – Interaction With Federal and State Anti-Discrimination Laws The employee may lose workers’ comp income by refusing, but the FMLA still protects the job for up to twelve weeks. Time spent voluntarily working a light duty assignment does not count against the twelve-week entitlement.6eCFR. 29 CFR 825.220 – Protection for Employees Who Request Leave Refusing light duty can also affect discipline decisions and unemployment eligibility, so the trade-off deserves careful thought before an employee walks away from an offer.
When the Obligation Runs Out
Light duty is temporary by design, and the employer’s legal duty to keep offering it doesn’t extend forever. Recoveries end in one of three ways: full recovery and return to the original job, partial recovery with permanent restrictions, or a determination that the employee cannot return to the prior role at all.
When a treating physician determines the employee has reached maximum medical improvement but permanent restrictions remain, the temporary light duty arrangement typically can’t continue indefinitely. The employer has no obligation under the ADA to convert it into a permanent invented position.1Office of the Law Revision Counsel. 42 USC 12111 Definitions The employer must still engage in the interactive process to look for a vacant existing position that fits the employee’s abilities before concluding that no accommodation is possible.4U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship Under the ADA
Job restoration rights tied to a light duty assignment under the FMLA expire at the end of the applicable twelve-month leave year.6eCFR. 29 CFR 825.220 – Protection for Employees Who Request Leave Once that window closes and if no suitable existing position can be found, the employer may lawfully end the employment relationship. Skipping the interactive process or failing to look for alternatives before reaching that point is where employers create liability. For employees, this transition is the moment when legal counsel matters most.
