In California, an employer can ask enough to confirm your absence fits a legitimate reason for sick leave, but they cannot require you to disclose your diagnosis, symptoms, or medical history for a routine sick day. Saying “I’m sick and using a sick day” or “I have a medical appointment” is generally enough. The rules tighten when you request extended medical leave or a disability accommodation, but even then the questions are limited to what a certification form specifically calls for.
What You Have to Tell Your Employer for a Sick Day
California’s Healthy Workplaces, Healthy Families Act lets you use accrued paid sick leave on an oral or written request.1California Legislative Information. California Labor Code 246 – Paid Sick Days Your employer can ask enough to know the time off falls within a qualifying purpose, and no further. Qualifying purposes include your own diagnosis, treatment, or preventive care, and the same for a covered family member.2Department of Industrial Relations. Healthy Workplace Healthy Family Act of 2014 (AB 1522)
So a general statement is enough. You do not have to name the illness, describe the symptoms, identify the doctor, or explain what a family member is being treated for. Volunteering more is your choice, not your obligation.
Your employer also cannot make you find a replacement worker before you take the day. That requirement is expressly prohibited by statute.3California Legislative Information. California Labor Code 246.5 – Paid Sick Days It shows up often in workplaces that carried over attendance rules from states without California’s protections, and it is not enforceable here.
Can Your Employer Require a Doctor’s Note
The paid sick leave statute does not authorize employers to condition your use of accrued time on a doctor’s note. The law requires sick days to be provided “upon the oral or written request of an employee,” with no documentation requirement attached.4Department of Industrial Relations. Healthy Workplaces, Healthy Families Act of 2014 – Paid Sick Leave Facts and Resources A policy that demands a note for every one- or two-day absence effectively imposes a barrier the law does not permit.
There is a narrow gray area. If an employer has documented evidence of a pattern suggesting abuse, like sick days consistently attached to weekends or holidays, it may have grounds to investigate that specific situation. Even then the response must be proportional, and a blanket note-for-every-absence rule does not become lawful just because one worker’s pattern looks suspicious.
What Changes When You Need Extended Leave
The rules shift when you need more than a few days. The California Family Rights Act provides up to 12 weeks of job-protected unpaid leave in a 12-month period for your own serious health condition or a family member’s.5California Legislative Information. California Government Code 12945.2 You qualify if you’ve worked for the employer for at least 12 months, logged at least 1,250 hours in the past year, and the employer has at least five employees. CFRA’s covered family members are broader than the federal FMLA’s, extending to grandparents, grandchildren, siblings, domestic partners, and one designated person per year.6New York Codes, Rules and Regulations. California Code of Regulations Title 2, Section 11087 – Definitions
For CFRA or FMLA leave, your employer can require a medical certification from your healthcare provider. The certification identifies the date the condition began, its expected duration, and the medical facts showing it qualifies as serious. If the leave is for your own condition, it also states that you cannot perform your job functions.7U.S. Department of Labor. Fact Sheet 28G – Medical Certification under the Family and Medical Leave Act You get at least 15 calendar days after the request to turn it in.8New York Codes, Rules and Regulations. California Code of Regulations Title 2, Section 11091 – Requests for CFRA Leave
Even with a certification in hand, your employer cannot call your doctor for follow-up questions about your condition. Under California regulations, contact with the healthcare provider is limited to authenticating the document itself. If the certification is incomplete or unclear, the employer must give you the chance to fix it rather than going around you.8New York Codes, Rules and Regulations. California Code of Regulations Title 2, Section 11091 – Requests for CFRA Leave
When you return, your employer can require a fitness-for-duty certification confirming you can resume work. It is limited to the condition that caused your leave. If you took time off for a back injury, the return exam cannot become a general medical screening.9U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Disability-Related Inquiries and Medical Examinations of Employees under the ADA
Disability-Related Questions Outside of Sick Leave
Both the federal Americans with Disabilities Act and California’s Fair Employment and Housing Act limit any employer question or medical exam that could reveal a disability. Once you are on the payroll, any disability-related inquiry has to be “job-related and consistent with business necessity.”9U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Disability-Related Inquiries and Medical Examinations of Employees under the ADA Turning a routine sick call into a chance to ask whether you have a chronic condition will not clear that standard.
If you ask for a workplace accommodation, your employer can request documentation, but only the minimum needed to confirm you have a qualifying limitation and that an accommodation would help. FEHA requires the employer to engage in a good-faith interactive process to identify limitations and possible solutions, and any medical exam is limited to the functional issue that prompted the request.10California Code of Regulations. California Code of Regulations Title 2, Section 11069 – Interactive Process
Does HIPAA Stop Your Employer From Asking
Not directly. HIPAA restricts healthcare providers, health plans, and healthcare clearinghouses. It does not restrict an employer acting as an employer.11U.S. Department of Health and Human Services. Employers and Health Information in the Workplace Your doctor cannot release your records to your employer without your authorization, but HIPAA does not gag your supervisor from asking questions.
The state law that does apply is California’s Confidentiality of Medical Information Act. Civil Code Section 56.20 requires every employer that receives medical information about an employee to establish procedures to keep that information confidential and to protect it from unauthorized use or disclosure.12California Legislative Information. California Civil Code 56.20 An employer generally cannot use or share your medical information without your written authorization, subject to narrow exceptions for benefits administration, leave eligibility, and legal process. Refusing to sign an authorization is not, by itself, a lawful reason to discipline you, though the employer can still act on the absence of information it legitimately needs to grant a request.
Retaliation for Using Sick Leave or Refusing to Overshare
California law prohibits your employer from firing, demoting, suspending, or otherwise punishing you for using accrued sick leave, attempting to use it, filing a complaint, or cooperating in an investigation.3California Legislative Information. California Labor Code 246.5 – Paid Sick Days If the employer takes an adverse action within 30 days of you exercising your rights, the law presumes retaliation, and the employer has to prove otherwise.
A common trap is the no-fault attendance policy. Some employers assign points for every absence regardless of reason. Labor Code Section 234 makes it a per se violation to count a legally protected sick day against you under that kind of system.13California Legislative Information. California Labor Code 234 If your workplace deducts attendance points for days you used accrued sick time, the policy is unlawful on its face.
The FMLA carries its own anti-retaliation rule for extended leave. Employers cannot treat your request for or use of FMLA leave as a negative factor in hiring, promotion, or discipline, and they cannot discourage you from taking it.14U.S. Department of Labor. Fact Sheet 77B – Protection for Individuals under the FMLA
Where to File a Complaint if Your Employer Crosses the Line
Which agency you go to depends on what the employer did.
- Labor Commissioner (DLSE): file here if you were punished for using paid sick leave or your sick leave was unlawfully withheld. Complaints can be submitted online, by mail, or in person at a Labor Commissioner’s Office. The deadline is generally one year from the adverse action.15Department of Industrial Relations. Retaliation and Discrimination Complaints
- Civil Rights Department (CRD): file here for illegal disability-related inquiries, medical discrimination, or retaliation for an accommodation request under FEHA. The deadline is three years from the last harm. You start with an intake form on the California Civil Rights System portal.16California Civil Rights Department. Complaint Process
- U.S. Department of Labor Wage and Hour Division: file here for federal FMLA violations, within two years of the violation.
The remedies are not mutually exclusive. If your employer’s conduct violates state sick leave law and FEHA, you can pursue both complaints at the same time.
