The short answer
Employers may not interfere with FMLA rights or retaliate against employees who use them. Prohibited actions include discouraging leave, cutting hours to avoid obligations, holding leave against someone in promotions or discipline, and counting FMLA leave under attendance policies. Complaints are generally raised within two years of the violation.
Interfering with, restraining or denying the exercise of FMLA rights is prohibited.
Discouraging an employee from using leave is named as a prohibited action.
Reducing work hours to sidestep FMLA obligations is prohibited.
FMLA leave may not be counted under an attendance policy.

The full explanation.
When the mood at work changes
Sometimes the problem is not a refusal. It is a shift in tone. Fewer good assignments. A comment about how the team is coping without you. A sudden interest in your punctuality that did not exist before you mentioned treatment.
The FMLA anticipates this. It does not only require employers to grant leave. It forbids them from punishing people who use it.
The prohibitions, in the law's own terms
The Department of Labor states that employers may not interfere with, restrain, or deny the exercise of, or the attempt to exercise, any FMLA right. Note the last clause. Even an attempt to exercise a right is protected.
Employers also may not discriminate or retaliate against employees for exercising FMLA rights, discharge workers for opposing unlawful FMLA practices, or punish anyone for filing charges, giving information, or testifying in FMLA proceedings.
Specific actions that are named
Abstract language is hard to apply to your own situation, so it helps that DOL lists concrete examples:
- Denying FMLA leave to eligible workers
- Discouraging employees from using available leave
- Reducing work hours to sidestep FMLA obligations
- Treating leave requests negatively in hiring, promotion or discipline decisions
- Counting FMLA leave under attendance policies
That last item quietly catches a lot of employers. Attendance point systems run automatically, and protected leave sometimes gets swept in by default rather than by malice. It is still not allowed.
Discouragement counts. An employer does not have to say no to have crossed the line.
Keep a record, starting now
You will not remember dates in six months. Nobody does, and cancer treatment makes it worse.
Write down what happened, when, who was present, and what was said, as close to the moment as you can. Save emails and messages somewhere outside your work account. Keep your leave designation notices.
None of this commits you to a fight. It just means the facts still exist if you decide you need them.
Raising a concern
There are two routes, and they are not exclusive.
Inside the company, put your concern to HR in writing and ask for a response in writing. Sometimes that alone corrects an administrative mistake, particularly with attendance coding.
Outside, the Wage and Hour Division investigates complaints. The Department of Labor explains that if violations cannot be satisfactorily resolved, it may bring action in court to compel compliance. Employees may also pursue private civil action against employers. The Division can be reached at 1-866-487-9243.
Do not lose track of the clock
There is a time limit. In general, any allegation must be raised within two years from the date of the violation.
Two years feels long from the inside of a bad month and short from the other side of a cancer year. If something happened, note the date, even if you are not ready to act.
Protecting your energy too
You are entitled to these protections and you are also entitled to decide how much of your remaining energy goes into enforcing them. Some people want to push. Others want to get through treatment and revisit it later.
Both are legitimate. What is not wise is letting the deadline pass without knowing it existed. Make the phone call, get the information, and then choose.
Know which right you are relying on
Sometimes what feels like retaliation is really a separate problem, such as an accommodation that was never put in place. Different laws cover different things, and naming the right one gets you a faster answer.
If you are not sure which applies, describe what happened rather than trying to categorise it. The Wage and Hour Division can tell you whether your situation falls under FMLA or belongs somewhere else.
Look after yourself while you sort it
Workplace conflict during treatment is genuinely draining, and it can bleed into how you feel physically. Tell someone in your life what is happening, and mention it to your care team if it is affecting your sleep or your appetite.

Common questions
My manager keeps hinting I should not take the leave. Is that a violation?
Discouraging employees from using available leave appears on the Department of Labor's list of prohibited actions. Write down what was said and when, then contact the Wage and Hour Division at 1-866-487-9243 to talk it through.
Can my treatment absences trigger attendance points?
Counting FMLA leave under attendance policies is listed among the prohibited actions. If points are appearing on your record for protected leave, raise it in writing with HR.
Is there a deadline for complaining?
In general, any allegation must be raised within two years from the date of the violation. Do not sit on a concern until you are certain.
What happens after I file?
The Wage and Hour Division investigates complaints. If violations cannot be satisfactorily resolved, the Department of Labor may bring action in court to compel compliance. Employees may also pursue private civil action.

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. Low-risk educational or organizational content. Medical facts are cited to authoritative sources.
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.
