In most cases, an employer in California cannot deny sick time to an eligible worker. The Healthy Workplaces, Healthy Families Act gives nearly every employee in the state the right to accrue and use at least 40 hours (five days) of paid sick leave each year, and blocking that right exposes an employer to fines, back pay orders, and lawsuits. A denial is only lawful in a few narrow situations, and even then, the reason has to be a real one under the statute, not a policy the employer invented.1California Department of Industrial Relations. Labor Commissioner’s Office Healthy Workplace Healthy Family Act of 2014 (AB 1522)
The Narrow Situations Where a Denial Is Legal
Three lawful reasons cover almost every legitimate denial. Anything outside them is worth challenging.
You Haven’t Hit the Eligibility Thresholds Yet
Paid sick leave in California is tied to two waiting periods. You must have worked at least 30 days in California within a year of your start date, and you cannot actually use accrued hours until your 90th day of employment. If you request time before you cross those lines, an employer can lawfully turn you down. After the 90th day, the accrued hours are yours to use.1California Department of Industrial Relations. Labor Commissioner’s Office Healthy Workplace Healthy Family Act of 2014 (AB 1522)
Your Accrued Balance Is Zero
Once you’ve used up your annual allotment, your employer doesn’t have to grant more paid sick time under this law. An employer can cap your annual usage at 40 hours or five days even if your accrued balance is higher.1California Department of Industrial Relations. Labor Commissioner’s Office Healthy Workplace Healthy Family Act of 2014 (AB 1522) Federal laws like the FMLA and ADA can still require unpaid leave in the right circumstances, which is covered further down.
Foreseeable Leave Without Reasonable Notice
For a planned absence, like a scheduled medical appointment, an employer can require reasonable advance notice if it has a written policy saying so. Skipping that notice can give the employer grounds to deny the request. For sudden illness or an emergency, the rule is different: you only have to notify your employer as soon as you reasonably can.
What Employers Cannot Use to Deny Your Request
Employers overreach most often on documentation. California’s paid sick leave law does not require you to produce a doctor’s note, a medical certification, or any diagnosis to use accrued sick time. If your employer conditions approval on paperwork the statute doesn’t require, that functions as an unlawful denial of a right the law guarantees.
Blanket policies also don’t override the statute. A company handbook that caps leave more strictly than California law, demands a diagnosis, or excludes reasons the statute covers (caring for a family member, addressing domestic violence, seeking preventive care) cannot legally be enforced against you.
Retaliation Counts as Denial in Practice
An employer who approves the leave on paper and then punishes you for taking it has violated the same law. California Labor Code Section 246.5 prohibits firing, threatening, demoting, suspending, or discriminating against any employee for using accrued sick days, trying to use them, filing a complaint, or cooperating in an investigation.2California Department of Industrial Relations. California Paid Sick Leave Frequently Asked Questions
Retaliation rarely looks like a termination letter. The common patterns are subtler: a shift to a less desirable schedule, a suddenly negative performance review, quietly reduced hours. Close timing between the sick leave and the adverse action is often enough to raise a strong inference that something improper happened.
These protections cannot be waived, even in a collective bargaining agreement.2California Department of Industrial Relations. California Paid Sick Leave Frequently Asked Questions
Discriminatory Denials
Federal law adds another layer. An employer cannot approve or deny sick leave based on race, color, religion, sex (including pregnancy and sexual orientation), national origin, age, disability, or genetic information. The EEOC treats sick and vacation leave approval as an employment decision subject to non-discrimination rules.3U.S. Equal Employment Opportunity Commission. Prohibited Employment Policies/Practices
Inconsistency is the tell. If two employees in similar roles call out under similar circumstances and only one gets approved, and the difference between them is a protected characteristic, that pattern can support a discrimination claim. The same reasoning applies to discipline: writing up one employee for sick leave use while ignoring the same behavior in others can be illegal.3U.S. Equal Employment Opportunity Commission. Prohibited Employment Policies/Practices
When Federal Law Forces More Leave Than California’s Minimum
Even after your paid sick leave runs out, a denial of further time off can still be unlawful under federal law.
Disability Accommodation Under the ADA
If you have a disability, unpaid leave can be a reasonable accommodation under the Americans with Disabilities Act. Your employer has to consider it even if you’ve already exhausted your accrued sick time, used up your FMLA leave, or aren’t eligible for leave under company policy.4U.S. Equal Employment Opportunity Commission. Employer-Provided Leave and the Americans with Disabilities Act
The employer’s only defense is showing that additional leave would cause “undue hardship,” meaning significant difficulty or expense measured against the employer’s resources. Complying with the FMLA alone doesn’t establish undue hardship. The assessment is case-by-case, looking at how much leave is needed, whether you can give a return date, and how the absence affects operations. A rigid policy capping leave at a fixed number of days won’t hold up if a disabled employee needs more.5U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship under the ADA
Attendance policies that penalize unplanned absences may need to be modified for disability-related absences too.4U.S. Equal Employment Opportunity Commission. Employer-Provided Leave and the Americans with Disabilities Act
Pregnancy Accommodations
Under the federal Pregnant Workers Fairness Act, an employer cannot force a pregnant or postpartum employee onto leave when a reasonable accommodation would let them keep working. Even if you temporarily cannot perform a core job duty, the employer has to accommodate rather than push you out, as long as you’ll be able to perform that duty in the near future. Paid or unpaid leave to recover from childbirth counts as a reasonable accommodation when needed.
Job-Protected FMLA Leave
The Family and Medical Leave Act provides up to 12 weeks of unpaid, job-protected leave per year for serious health conditions, the birth or adoption of a child, and certain other qualifying reasons.6U.S. Department of Labor. FMLA Frequently Asked Questions Eligibility is narrower than California’s sick leave law: the employer must have at least 50 employees within 75 miles, and you must have been employed at least 12 months with at least 1,250 hours logged in the past year.7U.S. Department of Labor. Fact Sheet 28 – The Family and Medical Leave Act
When both laws apply, your California paid sick leave can run concurrently with FMLA time, and the employer can require you to use accrued paid leave during an FMLA absence. Five paid sick days used during FMLA leave count against both balances at once.6U.S. Department of Labor. FMLA Frequently Asked Questions
What to Do If You’re Denied
Start with a quick check that the denial actually violates the law. Confirm you’ve cleared the 30-day and 90-day thresholds, look at your accrued balance on a recent pay stub (California requires it to appear there or on a document issued on the same payday), and read your employer’s written sick leave policy.1California Department of Industrial Relations. Labor Commissioner’s Office Healthy Workplace Healthy Family Act of 2014 (AB 1522) If it looks like an error, raising it with your manager or HR sometimes resolves it fast.
If the company doesn’t fix it, start documenting. Save emails, text messages, pay stubs, schedules, and any written communication about the denial. Note dates, times, and names. That paper trail matters if you file a complaint later.
The California Labor Commissioner’s Office enforces the paid sick leave law. You can file a report online, in person, or by mail to the office nearest where you performed the work.8California Department of Industrial Relations. Report a Labor Law Violation If you worked and weren’t paid for hours you should have been, you can also file a separate wage claim.9Division of Labor Standards Enforcement (DLSE). How to File a Wage Claim Enforcement can produce administrative fines, back pay for the denied leave, and reinstatement if you were terminated. Civil litigation can add damages beyond back pay.
If the denial appears tied to a protected characteristic like race, sex, disability, or pregnancy, a federal discrimination charge is also available. Private-sector employees generally have 300 days from the discriminatory action to file with the EEOC in California, because the state has its own civil rights agency. The EEOC investigates, and if the charge isn’t resolved, you may eventually have the right to sue in federal court.3U.S. Equal Employment Opportunity Commission.
