Fired After a Cancer Diagnosis in California? What Your Employer Can and Cannot Do

You told them because you had to. Treatment meant Tuesdays off, or a few weeks out, or a stretch where you would be slower than usual. Your manager said the right things. Then the assignments thinned, a performance conversation you had never had before appeared, and then came a meeting with HR and no agenda.

If you are reading this with a diagnosis in one hand and a termination letter in the other: none of this is your fault, and California protects you twice over. It starts at employers most people assume are too small to matter.

Labor Law PC was built by a lawyer who spent many years on the other side — defending companies in cases exactly like this one. We know the playbook employers run, and we use it only for employees, from our offices in Santa Monica and Palo Alto.

From Los Angeles to the Bay Area, we see this most in tech, entertainment, health care and retail, where a diagnosis becomes known fast.

Is It Illegal to Fire Someone for Having Cancer in California?

Yes, and California gets there by a route federal law does not have.

The Fair Employment and Housing Act lists “medical condition” as a protected characteristic in its own right, alongside race, sex, age and disability. Government Code section 12926, subdivision (i)(1), defines it to include “any health impairment related to or associated with a diagnosis of cancer or a record or history of cancer.” That reaches a past diagnosis, not only a current one, so being finished with treatment does not put you outside it.

The threshold matters as much as the category. For discrimination and accommodation claims, the Fair Employment and Housing Act covers any employer regularly employing five or more people. The federal Americans with Disabilities Act requires fifteen. California protects you as someone with a medical condition and, in most cases, as someone with a disability, which means two routes to the same protection.

What Accommodations Can You Ask For During Cancer Treatment?

Once you ask, your employer owes you a process. Government Code section 12940, subdivision (n), makes it unlawful “to fail to engage in a timely, good faith, interactive process” to determine effective reasonable accommodations. Timely. Good faith. Interactive. Each is a way to fall short.

What comes up most is a modified schedule, remote work during a treatment cycle, less physically demanding work, or time off running past whatever protected leave you had. Your employer can decline if an accommodation would cause undue hardship, and that is its burden to prove. It cannot retaliate against you for asking, whether or not the request was granted.

The protection does not stop when treatment does. The regulations provide that a person with a record of a disability may be entitled to accommodation related to its residual effects, and they name “a leave or a schedule change to permit him or her to attend follow-up or monitoring appointments” as an example. If you are in remission and were told you no longer qualify, that is not what the regulation says.

Signs the Decision Was Really About the Diagnosis

• Your record was clean until the month you disclosed
• Criticism is suddenly specific and written down, where before it was neither
• Work was reassigned “to take pressure off you,” without your asking
• Someone senior has referred to your reliability, your energy, or how long this will go on
• The reorganization that eliminated your position eliminated only yours

None of these alone means your employer broke the law. Every one means the timing deserves a look. We will not tell you a claim is there when it is not.

What to Do This Week

1. Write the timeline down now, while the dates are fresh. When you disclosed, to whom, what changed afterward, and who said what.
2. Put every accommodation request in writing, and keep the response, or the lack of one.
3. Save your past reviews and any praise from before you disclosed. A clean record is the first thing your employer will try to rewrite.

You don’t have to work out which protection applies before you call. A free, confidential review will tell you whether the timing adds up to a case — (877) 775-2267. No fee unless we win.

How Long Do You Have to File a Cancer Discrimination Claim in California?

Generally three years from the unlawful act to file with the Civil Rights Department, then one year from your right-to-sue notice to file suit. The three-year clock ordinarily runs from when the conduct happened, not from when you understood it, and limited extensions exist in narrow circumstances. Get your own dates checked rather than working them out from an article.
