Last updated: July 2026 — Reflects Government Code § 12940, Government Code § 12945.2 (CFRA), Government Code § 12926 (FEHA disability definitions), and California Civil Rights Department enforcement guidance current as of January 1, 2026. 1000Attorneys.com is a California State Bar Certified Lawyer Referral Service (LRIS #0128), American Bar Association Authorized Program, and LawHelpCA Verified Resource.
The short answer is no — with important qualifications. California law prohibits employers from firing employees because of a medical condition, disability, or illness under multiple overlapping statutes.
But the protections are not absolute; the employer's stated reason matters, and the timing of the termination relative to the disclosure of the illness or the medical leave request is the most important single factor in evaluating whether a termination was lawful.
Understanding which protections apply to your specific situation — and how they interact — is the difference between a valid legal claim and a termination that, while unfair, was legally permitted.
The Core Prohibition — FEHA and Medical Condition Discrimination
California's Fair Employment and Housing Act, codified at Government Code § 12940, prohibits employers with five or more employees from discriminating against employees based on physical disability, mental disability, or medical condition.
This protection is broader than its federal counterpart — the ADA's 15-employee threshold means FEHA covers smaller employers that federal law does not reach.
Under FEHA, a physical disability is any physiological condition that limits a major life activity. The definition is intentionally broad and has been interpreted to include temporary conditions — a broken leg, a post-surgical recovery period, a serious infection — not just permanent or chronic impairments.
A medical condition under FEHA specifically includes any health impairment related to or associated with a diagnosis of cancer or a record or history of cancer, as well as genetic characteristics. Cancer-related terminations have their own explicit statutory protection as a result.
The critical point is that the employer's discriminatory motive need not be the sole reason for the termination to constitute a FEHA violation.
Under California's substantial motivating factor standard established in Harris v. City of Santa Monica (2013) 56 Cal.4th 203, the illness or disability need only have been a real, meaningful contributor to the termination decision — not the only reason, and not even the primary reason.
The Reasonable Accommodation Obligation — What Employers Must Do Before Terminating
Before terminating an employee whose illness affects their ability to work, California employers are required to engage in the interactive process under Government Code § 12940(n).
The interactive process requires the employer and employee to engage in a good-faith dialogue to identify whether a reasonable accommodation exists that would allow the employee to perform the essential functions of their position.
A reasonable accommodation is any modification or adjustment that does not impose undue hardship on the employer.
Common accommodations for illness-related limitations include temporary leave, modified schedules, reduced hours during treatment, reassignment to a vacant position, and adjustments to work duties during recovery.
The employer's obligation to accommodate is not satisfied by offering a single option and terminating the process when the employee cannot accept it — the interactive process requires a genuine exploration of available alternatives.
An employer who terminates an ill employee without engaging in the interactive process has committed a separate FEHA violation regardless of whether a reasonable accommodation would ultimately have been possible.
Failure to engage in the interactive process is independently actionable under California law.
Protected Leave — CFRA, FMLA, and What Happens When You Request Time Off
Illness frequently triggers a request for protected medical leave. Two statutes govern that leave — and both prohibit termination for requesting or taking it.
The California Family Rights Act under Government Code § 12945.2 provides eligible employees at employers with five or more employees up to 12 weeks of job-protected leave per year for a serious health condition affecting the employee or a covered family member.
CFRA's five-employee threshold again exceeds the federal FMLA's 50-employee floor, meaning significantly more California employees have CFRA protection than FMLA protection.
Firing an employee for requesting CFRA leave, during CFRA leave, or upon return from CFRA leave violates § 12945.2, regardless of the employer's stated reason — unless the employer can establish that the termination would have occurred regardless of the leave.
The burden of proof on that "same decision" defense rests with the employer.
The timing of the termination relative to the leave request is the strongest evidence in an illness-related termination case.
An employer who terminates an employee within days or weeks of a medical leave request carries a heavy explanatory burden that most legitimate business justifications cannot satisfy.
When a Termination for Illness Is Lawful
Not every termination connected to an illness is actionable. California law recognizes that some employment separations connected to medical conditions are lawful.
An employee who cannot perform the essential functions of their position — even with reasonable accommodation — can be lawfully separated after the interactive process has been completed in good faith and no accommodation is available.
The key is that the employer must exhaust the interactive process before reaching that conclusion. Skipping the process and terminating based on an assumption that no accommodation is possible is itself a FEHA violation.
An employee who has exhausted all available CFRA and FMLA leave and remains unable to return to work may be terminated — but the employer must still evaluate whether additional leave, as a reasonable accommodation, is warranted before taking any action.
California courts have repeatedly held that leave beyond the CFRA/FMLA entitlement can constitute a reasonable accommodation when the duration is definite and the employee's return is medically certain.
The table below outlines the most common scenarios:
Scenario | Generally Lawful? | Key Condition |
Fired because of medical condition itself | ❌ No | FEHA § 12940 violation |
Fired for requesting CFRA/FMLA leave | ❌ No | § 12945.2 / FMLA retaliation |
Fired during protected leave | ❌ No | Unless same decision regardless of leave |
Fired after exhausting leave, unable to return | ✅ Sometimes | Only after good-faith interactive process |
Fired because cannot perform essential functions | ✅ Sometimes | Only if no reasonable accommodation exists |
Fired for legitimate reason unrelated to illness | ✅ Yes | Timing and pretext analysis critical |
Proving Pretext — How These Cases Are Won
Employers rarely admit illness-based discrimination. The legal challenge is proving that the stated reason for the termination is pretextual — that the real reason was the illness, disability, or medical leave request.
The strongest pretext evidence in illness-related termination cases is temporal proximity: termination occurring within days or weeks of a medical leave request, an illness disclosure, or a return from leave. Courts consistently recognize that tight timing supports an inference of illegal motive.
Combined with a clean personnel record that converts to a cascade of documentation only after the illness becomes known, or comparator evidence showing that employees without medical conditions were treated more favorably under equivalent circumstances, temporal proximity builds a strong pretext case.

Filing Deadlines — Act Before the Clock Runs Out
FEHA claims arising from illness-based termination must be filed with the California Civil Rights Department within three years of the adverse action under Government Code § 12960.
CFRA interference and retaliation claims carry the same three-year deadline. Federal FMLA claims must be filed within two years of the violation, or three years if the violation was willful.
Missing either deadline permanently bars the claim regardless of how strong the underlying facts are. The CRD filing is the required administrative prerequisite before a civil lawsuit can proceed — it is not optional and cannot be bypassed.

Frequently Asked Questions
Can I be fired for calling in sick in California?
Generally no — but it depends on the context. A single sick day under an accrued sick leave policy is protected under California's Healthy Workplaces, Healthy Families Act. Repeated absences due to a serious medical condition trigger FEHA disability protections and the obligation to engage in the interactive process before any termination. A termination that coincides with sick leave usage — especially when preceded by a clean performance record — is strong pretext evidence for a wrongful termination claim. See our detailed guide on being fired for calling in sick in California.
What if my employer says I was fired for performance, not illness?
Performance defenses are the most common employer response in illness-related termination cases. The relevant questions are: when did the performance documentation appear relative to the illness disclosure, were similarly situated healthy employees held to the same standards, and did the employer follow its own progressive discipline policy before terminating. A performance narrative that emerges only after a medical leave request is itself evidence of pretext.
Does FEHA protect temporary illnesses, not just permanent disabilities?
Yes — California's FEHA definition of physical disability is broader than the ADA and explicitly covers temporary conditions that limit a major life activity. A post-surgical recovery, a serious infection requiring extended leave, or a short-term condition that prevents performance of essential job functions can all qualify for FEHA protection even if the condition is fully expected to resolve.
What is the interactive process and what happens if my employer skips it?
The interactive process is the employer's mandatory obligation to engage in a good-faith dialogue with the employee about available reasonable accommodations before making an adverse employment decision based on a disability or medical condition. An employer who terminates an ill employee without engaging in the interactive process has violated FEHA independently of whether the underlying termination was also discriminatory. Failure to engage is a separate cause of action with its own damages.
Can I sue if I was fired while on approved medical leave?
Yes — termination during approved CFRA or FMLA leave is a violation of those statutes regardless of the employer's stated justification, unless the employer can establish that the same termination decision would have been made regardless of the leave. The burden of proving that "same decision" defense rests with the employer. Termination during leave is among the strongest factual patterns for a California medical leave wrongful termination claim.
How long do I have to file a claim if I was fired because of an illness?
Three years from the date of termination to file with the California Civil Rights Department for FEHA claims. Two years for federal FMLA claims, or three years if the violation was willful. These deadlines run from the date of termination — not from when you retained an attorney or learned of your rights. Acting promptly preserves all available options.
