The short answer
How to keep working through chemotherapy: mapping your good and bad days to the cycle, requesting accommodations under the ADA, using intermittent FMLA, and how little you are required to disclose.
Chemotherapy runs in cycles, and side effects follow a predictable rhythm. Mapping your first cycle tells you which days of each subsequent cycle you can realistically work.
You do not have to tell your employer you have cancer to request an accommodation. There are no magic words required, and the ADA restricts what medical detail an employer can demand or share.
The ADA applies to private employers with 15 or more employees and to state and local government. Cancer is covered while active, in remission, as a record of past cancer, and where an employer merely regards you as having it.
FMLA can be taken intermittently — hours or days at a time — which fits chemotherapy well, but eligibility is narrow: 12 months with the employer, 1,250 hours of service in the previous 12 months, and 50 employees within 75 miles. FMLA leave is unpaid.

The full explanation.
Work around the cycle, not around your willpower
Chemotherapy is given in cycles. You get treatment, then a recovery gap, and then it repeats. That structure is the single most useful thing about it for anyone trying to keep a job. The bad days are largely predictable once you have been through one cycle.
Spend cycle one taking notes. Which day did the steroids wear off? Which day was nausea worst? When did the fog lift? When were you hungry again? By cycle two you can plan a working fortnight instead of gambling on each morning. Most people find a rough pattern. A few flattened days after infusion, a trough in the middle, and a better stretch just before the next cycle starts.
Ask your team when your nadir falls. That is when infection-fighting white cells are lowest. It is the worst window for an open-plan office, a classroom or a shop floor. It is also the period where a fever counts as a medical emergency, in CDC's words, rather than something to mention at the next visit. CDC marks it at 100.4°F (38°C); the National Cancer Institute uses 100.5°F. Take whichever number your team gave you, phone the 24-hour oncology line the moment you hit it, and if no one answers within minutes, call 911 or go to an emergency department. Do not finish your shift first.
What you have to say, and to whom
You do not have to announce a cancer diagnosis at work. Under the ADA you have to request what you need. The EEOC is explicit that there are no magic words for doing it. The request can even come from a family member or your doctor.
The law does let your employer ask for medical documentation showing that you need the adjustment. It does not let your employer tell colleagues why you are being accommodated. Medical information must be kept confidential. There are narrow exceptions, such as supervisors who need to know about restrictions, and first-aid staff.
Here is a practical shape for the request. Put it in writing and keep it short. Describe the limitation and the fix, not the diagnosis. Keep a dated copy. This is a complete request: "I need a modified schedule on Mondays and Tuesdays for the next four months for a medical condition, and I can provide documentation."
Accommodations that hold up under chemo
The Job Accommodation Network is free and confidential. The Labor Department's Office of Disability Employment Policy funds it. Staff will talk through options with you or your employer at (800) 526-7234. Their cancer list is worth reading in full. These items come up most:
- Flexible or part-time scheduling, and telework on predictable bad days
- Rest breaks, and somewhere private to take them
- Moving demanding tasks to your best hours rather than your worst
- Written instructions, task breakdown and reminders for chemo-related concentration problems
- A small fridge for medication and food, and odour control for nausea triggers
- Temperature control and ergonomic changes for neuropathy
- Adjusted attendance policies, so treatment days do not trigger discipline
The ADA covers private employers with 15 or more employees. It also covers state and local government. Cancer is covered while you have it and while you are in remission. It is covered as a record of past cancer. It is covered where an employer wrongly assumes you have it. Employers can refuse an accommodation that causes significant difficulty or expense. They can also refuse one that removes an essential function of the job.
Leave, and the eligibility that trips people up
In principle, FMLA fits chemotherapy well. You can take it intermittently, in separate blocks of time or as a reduced schedule, when medically necessary. It gives up to 12 workweeks in a 12-month period. Your job, or an equivalent one, is held for you. Your group health coverage continues.
Say the limits plainly, because a great many people do not qualify. You need 12 months of employment with that employer. You need at least 1,250 hours of service in the previous 12 months. And you need a worksite with 50 or more employees within 75 miles. FMLA is unpaid. Employers may let you use accrued paid leave at the same time, or may require it.
If you fall outside those thresholds, the ADA is still available. Unpaid leave can itself be a reasonable accommodation. So are your employer's own policies, and short-term disability insurance if you have it. So is any state paid family and medical leave program. State rules vary considerably, and none of this is legal advice.
Deciding how much work is the right amount
Work keeps structure, income and insurance. For many people it is the one part of life that still feels normal. It can also quietly consume the energy you needed for recovery. It is reasonable to reduce hours for a defined period. Revisit that decision each cycle rather than committing for the whole course. Ask your team what they are seeing. Oncology nurses have watched hundreds of people try this, and they tend to give straight answers.

Common questions
Do I have to tell my employer I have cancer?
No. You have to request what you need. An accommodation request can come from you, a family member or your doctor, and the EEOC is explicit that no particular wording is required. Your employer may ask for medical documentation supporting the need, but it must keep any medical information confidential and may not explain to colleagues why you have an accommodation.
What accommodations do people actually get?
The common ones are a modified or part-time schedule, telework, more frequent breaks, a private space to rest, leave for treatment and recovery, adjustments to attendance policies, temperature control, and redistributing physically demanding tasks. JAN also lists supports for chemo-related cognitive changes such as written instructions, task breakdown and reminders.
What if I don't qualify for FMLA?
Many people don't — the 1,250-hour, 12-month and 50-employee thresholds exclude part-timers, recent hires and small-employer staff. In that case the ADA route still exists, since unpaid leave itself can be a reasonable accommodation. Also check your employer's own leave and short-term disability policies and whether your state runs a paid family and medical leave program; several do, with their own rules.
Should I try to work on infusion day?
Some people do light work during infusion and regret it; others find it passes the time. The more important question is the two or three days afterwards, when steroids wear off and nausea and fatigue peak. Protect those days deliberately rather than planning to see how you feel.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
