Terminating an Employee with Cancer: ADA, Retaliation, and Risks

Firing an employee who has cancer is legal only when the reason has nothing to do with the diagnosis, the treatment, or any accommodation the employee has asked for. Cancer is treated as a disability under federal law, so the termination has to stand on ground the employer would have acted on for any other worker, and it has to be documented that way. Get it wrong and the company can be looking at back pay, front pay, capped compensatory and punitive damages up to $300,000, attorney’s fees, and possibly a parallel claim under ERISA for interfering with health benefits.

Cancer Is a Disability Under Federal Law

The Americans with Disabilities Act covers employers with 15 or more workers and forbids discrimination based on disability.¹ After the 2008 ADA Amendments Act, the EEOC’s guidance says people who currently have cancer or whose cancer is in remission “should easily be found to have a disability” because the disease substantially limits normal cell growth, a major bodily function the amended law recognizes.²

Coverage runs in three directions. An employee with an active diagnosis is protected. Someone with a history of cancer is protected under the “record of” prong even if cancer-free today. And an employee is protected under the “regarded as” prong if the employer takes adverse action because it believes the person has cancer, whether or not that belief is right.² Arguing that a cancer diagnosis doesn’t qualify almost never works now.

Leave Rights That Come Before Termination

Before an employer can treat absence as a firing offense, it has to reckon with two separate leave entitlements.

The Family and Medical Leave Act gives an eligible employee up to 12 weeks of unpaid, job-protected leave in a 12-month period for a serious health condition, and cancer qualifies.³ The employee can take it in one block or in smaller pieces for chemotherapy, radiation, or recovery days. To be eligible, the worker must have been employed for at least 12 months, logged at least 1,250 hours in the previous 12 months, and work at a location where the employer has 50 or more employees within 75 miles.⁴ Firing someone for using FMLA leave they were entitled to creates liability under the FMLA and often under the ADA as well.

Twelve weeks is frequently not enough for cancer treatment, and this is where many employers slip. Once FMLA runs out, they assume termination is automatic. It isn’t. Additional unpaid leave beyond FMLA’s 12 weeks can be a required reasonable accommodation under the ADA, unless the employer can show undue hardship.⁵ The difference is between a bounded request and an open-ended one. The EEOC has stated that truly indefinite leave, where the employee cannot say whether or when they will be able to return, is an undue hardship and doesn’t have to be granted.⁶ An employee who says they need four more weeks and expects to return in early March is making a specific, bounded request, and denying that without exploring alternatives is risky. If the original position cannot be held open without hardship, the employer still has to consider reassigning the employee to a vacant role.

About a dozen states and the District of Columbia also run mandatory paid family and medical leave programs. Duration varies but generally falls between 8 and 16 weeks. Employers in those jurisdictions have to account for state-level entitlements that may overlap with or extend beyond FMLA.

The Accommodation Duty and the Interactive Process

The ADA requires reasonable accommodations that let an employee with cancer keep performing the essential functions of the job, unless the accommodation would impose an undue hardship.⁵ Common accommodations for someone in treatment include modified schedules, remote work on bad days, extra rest breaks, temporarily reassigning non-essential duties to coworkers, and workspace adjustments. The employer doesn’t have to grant the employee’s preferred accommodation, but it does have to provide one that actually works.

Undue hardship is a real defense, and it turns on the cost of the accommodation relative to the employer’s overall resources, workforce size, and the operational disruption involved. Declaring hardship without evidence won’t hold up. The larger and more profitable the company, the harder that defense is to sustain.

An employee triggers the accommodation duty by putting the employer on notice that something at work needs to change because of the illness. No magic words are required. Saying “chemo is making it hard to get here by 8 a.m.” is enough. The employer’s obligation is to open a dialogue about what the worker needs and what solutions are workable, request narrow medical documentation if needed, and either provide a workable accommodation or offer alternatives.⁵ An employer that ignores the request, refuses to participate, or stonewalls can face liability for that failure alone, separate from any claim tied to the termination.

Reasons for Termination That Hold Up

Disability protection does not make an employee with cancer immune from being fired. It prevents the cancer from being the reason. If the basis is genuinely independent of the diagnosis or any accommodation request, the decision can stand. The timing, the paper trail, and how comparable employees have been treated all matter.

Performance Problems

Poor performance is the most common legitimate ground, but the documentation has to exist before the diagnosis enters the picture. Six months of written warnings, a failed improvement plan, and consistent feedback create a defensible record. Performance concerns that first surface after chemotherapy begins do not. The standards applied must match those used for every other employee in the same role, and the worker must have had a real chance to improve.

Misconduct

Policy violations, dishonesty, and insubordination are legitimate bases for termination regardless of disability status. The test is whether the employer would have taken the same action against any other employee who engaged in the same conduct.

Layoffs and Restructuring

A reduction in force can justify terminating an employee with cancer, but the selection criteria have to be objective and applied consistently. Before implementing a layoff, employers should review whether the criteria disproportionately affect workers with disabilities and adjust where possible while still meeting business goals.⁷ Seniority, productivity, or specific skill sets are defensible. A selection process that lacks documentation, or that conveniently eliminates the employee with the highest anticipated medical costs, is not.

Direct Threat

An employer can occasionally argue that an employee’s condition creates a significant risk of substantial harm that no reasonable accommodation could eliminate. The determination cannot rest on stereotypes about cancer. It requires an individualized assessment of the employee’s current ability to do the job safely, based on objective medical evidence, weighing the duration of the risk, the severity of potential harm, and its likelihood and imminence.⁸ This defense almost never applies to cancer. It is more commonly invoked for conditions that cause sudden loss of consciousness in safety-sensitive work.

Retaliation Is Its Own Violation

Even when the underlying grounds are defensible, a termination becomes illegal if retaliation is a motivating factor. The ADA explicitly prohibits adverse action against an employee for requesting an accommodation, filing a discrimination complaint, or participating in an investigation.⁹ Retaliation is often easier to prove than the underlying discrimination because the timeline tells the story. An employee who was performing well, asked for a modified schedule, and was fired two weeks later has strong circumstantial evidence whatever the termination paperwork says.

The law also forbids coercion. A manager who pressures an employee to drop an accommodation request or discourages them from filing a complaint creates independent exposure even if no one is fired.

Documentation That Will Actually Defend the Decision

Documentation is what separates a defensible termination from a lawsuit. The employer needs a written trail showing the decision rested on legitimate business reasons that existed independently of the cancer.

The most important records are performance reviews conducted consistently over time, not just in the weeks before termination. Written warnings, coaching notes, and formal improvement plans show the employee knew about the problems and had a fair chance to address them. A pattern of documentation that begins only after the employer learns of the diagnosis is devastating in litigation because it looks like the employer went hunting for a justification.

For layoffs, document the selection criteria, the business rationale, and how the criteria were applied across the workforce.¹⁰ Preserve every email, meeting note, and HR memo. Destroying documents after a termination, even routinely, can create an inference that the destroyed material was unfavorable.

Document the interactive process too: the initial request, what was discussed, what was offered, and the reason for any denial. If the employee refused a reasonable accommodation, put that refusal in writing. This record demonstrates good faith even if the employment relationship ends.

Firing to Avoid Medical Costs Is a Separate Federal Violation

ERISA Section 510 makes it illegal to discharge a plan participant to interfere with their rights under an employee benefit plan or to keep them from becoming entitled to benefits they would otherwise receive.¹¹ An employer that fires a cancer patient soon after learning the diagnosis will drive expensive insurance claims faces exposure under both the ADA and ERISA. The motivation doesn’t have to be the only reason; it just has to be a motivating factor.

What an Illegal Termination Costs

An employee who proves an ADA violation can recover back pay covering wages and benefits lost from termination through judgment, and front pay for future lost earnings where reinstatement is impractical.¹² Neither is subject to a statutory cap.

Compensatory damages for emotional distress and punitive damages for willful violations are capped by employer size:¹³

15 to 100 employees: $50,000
101 to 200 employees: $100,000
201 to 500 employees: $200,000
More than 500 employees: $300,000

These caps apply to the combined total of compensatory and punitive damages per complainant, not to each category separately. Courts can also order reinstatement and award attorney’s fees to the prevailing employee, which in complex cases exceed the damages themselves. State disability discrimination claims, where available, may add uncapped damages on top.

Timing matters on the employee’s side. A charge of discrimination has to be filed with the EEOC within 180 calendar days of the termination, extended to 300 days where a state or local agency enforces a comparable law, which covers most states.¹⁴ Missing that window generally forfeits the federal claim. For the employer, the same window is the difference between a manageable investigation and a scramble to assemble records that reveal gaps.

Severance Releases

Employers often offer severance in exchange for a release of legal claims. These releases are enforceable when properly drafted, but the requirements vary by the employee’s age.

For workers age 40 and older, the Older Workers Benefit Protection Act imposes strict rules. The release must be written in plain language, specifically identify the rights being waived, advise the employee in writing to consult an attorney, and give the employee at least 21 days to consider it, or 45 days if the release is part of a group layoff. The employee must also have at least 7 days after signing to revoke.¹⁵ The release cannot cover claims that arise after signing, and the employee has to receive something beyond what they were already owed.

For employees under 40, no equivalent statute prescribes the exact form, but general contract principles apply. The release has to be knowing and voluntary, the consideration has to be real, and a release obtained through fraud or coercion is voidable. Courts scrutinize these agreements closely when the employee is dealing with a serious illness and a job loss at the same time.

Small Employers Are Not Automatically Off the Hook

The ADA’s 15-employee threshold means workers at very small companies fall outside federal disability protection.¹ State law usually fills the gap. Many states have their own disability discrimination statutes with lower employee thresholds, and some reach employers with as few as one worker. A small-business owner assuming the federal 15-employee floor is the ceiling is often wrong, and the state civil rights or human rights agency is the place to check before making the decision.
