Top 5 Mistakes California Employees Make When Requesting FMLA or CFRA Leave

The mistakes that most often cost California workers their family or medical leave are simple ones: telling your employer too late or too vaguely, missing the deadline to return a medical certification, assuming your workplace is too small to be covered, confusing a paycheck program with job protection, and not keeping track of the leave you’ve used. Each one is avoidable. Give clear notice in writing, return paperwork on time, and keep your own records, and you put yourself in a much stronger position if your employer later pushes back.

Mistake 1: Giving notice too late or too vaguely

Under both laws, when your need for leave is foreseeable, such as a scheduled surgery or a planned birth, your employer can require at least 30 days’ advance notice. When 30 days isn’t practicable, you must give notice as soon as practicable. Under California’s CFRA regulations (2 CCR §11091), your employer can’t deny leave for an emergency just because you couldn’t give advance notice, as long as you told them as soon as you could.

You don’t have to say “CFRA” or “FMLA.” Verbal notice is enough if it tells your employer you need leave and why. The mistake is being so vague that your employer can’t tell the leave may be protected. “I need some time off” is weak. “My mother is having heart surgery on March 3 and I need about four weeks to care for her” gives your employer what it needs.

Two more traps:

• Ignoring your employer’s call-in rules. Under the federal rules, your employer can require you to follow its usual notice procedures, such as calling a specific person. Skipping them without a good reason can delay your protected leave (29 CFR §825.302).
• Not mentioning a prior approved reason. If you were already approved for leave for a condition and need more time for it, the FMLA rules say you should specifically reference that reason.

Hypothetical: Luis tells his supervisor on Friday that he “might be out for a while.” He stops coming in Monday after his father’s stroke and doesn’t answer HR’s questions. Because his employer couldn’t tell whether the absence qualified, he risks losing protection. A short email the same day explaining the stroke and his expected absence would have put him on solid ground.

Mistake 2: Missing the certification deadline

Your employer may ask for a certification from a health care provider. Under CFRA, it must give you no less than 15 calendar days from its request, unless getting the form in that time isn’t practicable despite your good-faith efforts. The Department of Labor gives the same 15 calendar days under the FMLA.

For your own condition, a CFRA certification generally states when the condition began, how long it will probably last, and that you can’t perform your job. For a family member, it adds an estimate of the time you’re needed and that the condition warrants your participation in care. Your employer can’t ask for symptoms or a diagnosis beyond what the rules allow.

What happens if you miss the deadline? Under 2 CCR §11091(b), your employer may deny CFRA protection for the leave after the 15 days run until you provide a sufficient certification, and if you never provide one, the leave isn’t CFRA leave. So:

• Ask for the form in writing and note the date you received it.
• Get the appointment scheduled right away, and tell HR in writing if your provider is slow.
• Keep a copy of what you submit and when.

If your employer has a good-faith, objective reason to doubt a certification for your own condition, it can require a second opinion at its own expense, and if the two opinions conflict, a third opinion that binds both sides. Recertification generally comes up only when you ask for more leave after the original estimate runs out.

Mistake 3: Assuming your employer is too small

Many workers hear that the FMLA needs 50 employees and stop there. In California, that’s the wrong test for most people.

CFRA also covers more relatives than the FMLA, including grandparents, grandchildren, siblings, parents-in-law, domestic partners and a designated person. If you’re pregnant, pregnancy disability leave has no length-of-service requirement at all. See our side-by-side guide to how CFRA and the FMLA compare and pregnancy disability leave in California.

Mistake 4: Confusing pay with job protection

CFRA and FMLA leave are unpaid. They protect your job, your health coverage and your right to return to the same or a comparable position. California’s state programs work the other way around:

• Paid Family Leave (PFL) pays up to 8 weeks in a 12-month period to bond with a new child, care for a seriously ill family member or help with a family member’s military deployment.
• State Disability Insurance (SDI) pays when you can’t work because of your own illness, injury or pregnancy.
• Both pay roughly 70% to 90% of your earlier wages, from $50 to $1,765 a week as of 2026.

PFL doesn’t give you the right to come back to your job. If you file only for PFL and never request CFRA leave from your employer, you may have pay without protection. Request the leave from your employer and apply to EDD separately. Your employer may require you to use accrued vacation or paid time off during CFRA leave, but since January 1, 2025, it can’t make you use up to two weeks of vacation before PFL benefits begin. More in our guide to SDI, Paid Family Leave and job protection.

Mistake 5: Not tracking your leave

When a reason qualifies under both laws, CFRA and FMLA leave usually run at the same time, so the same weeks count against both. Intermittent leave, a day here and half a day there, is especially easy to lose track of. Workers who don’t keep their own count sometimes find out too late that HR thinks their 12 weeks are used up.

• Log the date, hours and reason for every absence.
• Ask HR in writing how much protected leave it has counted and under which law.
• Save every email, text, form and approval letter.

Under CFRA rules, your employer must respond to your leave request within five business days of receiving it. If you don’t hear back, follow up in writing and keep the record.

A related mistake: staying quiet about pushback

It can violate CFRA for an employer to deny, interfere with or discourage leave you’re entitled to, or to fire, demote or discipline you for requesting or taking it (Gov. Code §12945.2(k), (q)). Write down negative comments, sudden write-ups, schedule cuts or a termination soon after your leave. You generally have three years to file a complaint with the Civil Rights Department, and the FMLA has its own two-year deadline (three for willful violations). See retaliation claims in California.

A simple checklist before you request leave

1. Confirm which laws apply: employer size, your months of service and your hours.
2. Send a dated written request that explains the reason and expected timing.
3. Follow your employer’s call-in or HR procedures.
4. Return any certification within 15 calendar days and keep a copy.
5. Apply to EDD for PFL or SDI if you need wage replacement.
6. Log every leave day and save every message.

Frequently asked questions

Do I have to tell my employer my diagnosis?

No. A certification can confirm that you have a serious health condition, when it started, how long it’s expected to last and that you can’t do your job. Your employer generally can’t demand your diagnosis or symptoms.

Can my employer deny leave because I didn’t give 30 days’ notice?

Not if the need was unforeseeable and you gave notice as soon as practicable. For foreseeable leave, failing to give the required notice without a good reason can delay protected leave.

Does applying for Paid Family Leave protect my job?

No. PFL is a wage-replacement program. Job protection comes from CFRA, the FMLA or pregnancy disability leave, so you need to request leave from your employer too.

What if my employer says I’ve used up my leave?

Compare its count with your own log, and ask in writing how the leave was counted and under which law. If the numbers don’t match, or you were punished for taking leave, talk to an employment lawyer.
