In most cases, your employer cannot simply force you onto disability leave, cut your hours, or move you into a lower job just because of a health condition or perceived limitation. Under the federal Americans with Disabilities Act (ADA), an employer must keep a qualified employee in their job and provide reasonable accommodations unless doing so causes an undue hardship. Pushing a worker out of their role — onto leave or into a different position — against their wishes can be unlawful disability discrimination, especially when the employee can still do the essential parts of the job with or without accommodation.
That said, the answer is not an absolute "never." There are narrow situations where leave or reassignment is legal. The key is whether your employer is following the law's process — an honest, individualized look at what you can do — or simply making assumptions about your abilities. This article walks through where the line sits and what you can do about it.
The federal baseline: the ADA and who enforces it
The main federal law here is the ADA, enforced by the U.S. Equal Employment Opportunity Commission (EEOC). It generally covers private employers with 15 or more employees, as well as state and local governments. Federal employees and many contractors are covered under a closely related law, the Rehabilitation Act. The ADA protects three groups: people with an actual disability, people with a record of one, and people who are "regarded as" having a disability — even if they are not actually limited at all.
That "regarded as" category matters enormously in forced-leave cases. If your employer assumes you can't handle your job because of a health condition and pushes you out — even when you never asked for anything and could do the work fine — you may be protected precisely because the employer is acting on a perception. You do not have to prove you are "really" disabled to challenge that kind of decision.
The ADA's core promise is reasonable accommodation. If you can perform the essential functions of your job with some adjustment — a modified schedule, equipment, a temporary lighter duty, telework, or unpaid leave — the employer is generally required to provide it unless it would cause significant difficulty or expense (an "undue hardship"). Importantly, the law says your job is the accommodation it should try to keep you in. Reassignment to a different role is meant to be a last resort, used only when no accommodation lets you stay in your current position.
Can my employer force me to go on disability leave?
Usually not, if you can still do your job. A common scenario looks like this: you have a medical condition, a surgery, or a doctor's note with restrictions, and your employer responds by putting you on leave "for your safety" — even though you didn't ask to leave and believe you can keep working. Under the ADA, the employer can't just decide for you that you're too disabled to work. It must engage in what the law calls the "interactive process": an honest, back-and-forth conversation about your limitations and what accommodations might let you stay.
Forcing leave instead of exploring accommodations is one of the most frequently litigated ADA problems. Courts have repeatedly found that involuntary leave can itself be an "adverse action" — a harm that supports a discrimination claim — when the worker could have continued with a reasonable accommodation. Leave is supposed to be a form of accommodation the employee can use, not a way to remove someone the employer no longer wants to deal with.
There are limits. An employer may lawfully require leave or remove you from a specific task if you pose a "direct threat" — a significant risk of substantial harm to yourself or others that can't be reduced by accommodation. But this must be based on objective medical evidence and an individualized assessment, not stereotypes or a vague worry. Likewise, if your own doctor imposes restrictions that genuinely prevent you from doing the essential functions and no accommodation exists, leave may be appropriate. The problem is when employers skip the analysis and jump straight to "go home."
Note that disability insurance (like long-term disability benefits or Social Security Disability) is a separate matter. Your employer can't make you apply for or accept those benefits as a condition of keeping your job, and being placed on them does not erase your ADA rights.
Can my employer reduce my hours because of my disability?
Cutting your hours specifically because of a disability — rather than for legitimate business reasons that apply to everyone — can be disability discrimination. If you can perform your full-time role with or without accommodation, the employer generally can't unilaterally shrink your schedule based on assumptions about your stamina or health.
The nuance: a reduced schedule can also be a reasonable accommodation that you request — for example, part-time work during recovery. That's different from the employer imposing a cut you never asked for. Watch for situations where reduced hours are used to push you below a benefits threshold, drop you from group health coverage, or pressure you to quit. Reducing hours and pay so dramatically that a reasonable person would feel forced to resign can amount to "constructive discharge," which the law often treats the same as an illegal firing.
When reassignment to a different job is — and isn't — allowed
Reassignment is permitted in specific circumstances. If, even with accommodations, you truly cannot perform the essential functions of your current position, the ADA may require the employer to reassign you to a vacant position you're qualified for, as a last-resort accommodation. In that scenario, reassignment is a benefit to you, not a punishment.
It becomes a problem when the employer:
