Offer Letter Law in California
California does not require a formal "offer letter," but employers must provide a written notice at hiring with 10 specific items (Cal. Lab. Code § 2810.5). The state also prohibits noncompete clauses, salary history inquiries, and certain out-of-state forum selection provisions.
Is a written offer letter required in California?
California does not require a formal "offer letter," but employers must provide a detailed written notice at the time of hiring with 10 specific categories of information (Cal. Lab. Code § 2810.5). This mandatory notice must be in the language the employer normally uses for employment-related information.
What must be included in the mandatory hiring notice?
The Cal. Lab. Code § 2810.5 notice must include: - (A) The rate or rates of pay and the basis (hourly, salary, commission, etc.), including overtime rates (Lab. Code § 2810.5(a)(1)(A)) - (B) Any allowances claimed as part of the minimum wage (meal or lodging allowances) (Lab. Code § 2810.5(a)(1)(B)) - (C) The regular payday (Lab. Code § 2810.5(a)(1)(C)) - (D) The employer's legal name and any "doing business as" names (Lab. Code § 2810.5(a)(1)(D)) - (E) The physical address of the main office or principal place of business, plus mailing address if different (Lab. Code § 2810.5(a)(1)(E)) - (F) The employer's telephone number (Lab. Code § 2810.5(a)(1)(F)) - (G) The workers' compensation insurance carrier's name, address, and telephone number (Lab. Code § 2810.5(a)(1)(G)) - (H) Sick leave information: the right to accrue and use sick leave, prohibition on retaliation, and right to file complaints (Lab. Code § 2810.5(a)(1)(H)) - (I) Any federal or state emergency or disaster declaration applicable to the county of employment issued within 30 days before the first day of employment (Lab. Code § 2810.5(a)(1)(I)) - (J) Any other information the Labor Commissioner deems material and necessary (Lab. Code § 2810.5(a)(1)(J))
Employers must update employees in writing within seven calendar days after the time of the change, unless changes appear on a timely wage statement or other required writing (Lab. Code § 2810.5(b)).
Temporary services employers must additionally include the name, physical address, mailing address, and telephone number of the legal entity for whom the employee will perform work (Lab. Code § 2810.5(a)(3)).
H-2A agricultural employers must provide a separate Spanish-language section with additional rights and protections and must use the Labor Commissioner's template starting March 15, 2024 (Lab. Code § 2810.5(a)(4), (d)).
Who is exempt from the § 2810.5 notice requirement?
| Exemption Category | Description |
|---|---|
| Public employees | Employees directly employed by the state or any city, county, city and county, or special district (Lab. Code § 2810.5(c)) |
| Overtime-exempt employees | Employees exempt from overtime wages by statute or Industrial Welfare Commission wage order (Lab. Code § 2810.5(c)) |
| CBA-covered employees | Employees covered by a valid collective bargaining agreement that expressly provides for wages, hours, and working conditions; provides premium overtime rates; and provides a regular hourly rate at least 30% above the state minimum wage (Lab. Code § 2810.5(c)) |
What can I do if my employer didn't provide the required hiring notice?
Employees can file a complaint with the Division of Labor Standards Enforcement (DLSE) or bring a civil action under the Private Attorneys General Act (PAGA) to recover civil penalties for the Labor Code violation (Lab. Code § 2699). Civil penalties recovered are distributed 65% to the Labor and Workforce Development Agency and 35% to the aggrieved employees.
What clauses are prohibited in California offer letters?
Noncompete Clauses
California voids all noncompete clauses in employment contexts, regardless of how narrowly tailored (Bus. & Prof. Code § 16600(b)(1)). Employers cannot enforce noncompete clauses even if the employee signed outside California, the contract specifies another state's law, or the restriction is limited in duration or scope (Bus. & Prof. Code § 16600.5). Including a noncompete clause exposes employers to private lawsuits for injunctive relief, actual damages, attorney's fees, and unfair competition liability (Bus. & Prof. Code § 16600.5(e)).
Salary History Inquiries
Employers cannot ask about or rely on an applicant's salary history when deciding whether to hire or what salary to offer (Lab. Code § 432.3(a)-(b)). The only exception: employers may consider salary history if the applicant voluntarily discloses it (Lab. Code § 432.3(h)).
Out-of-State Forum or Choice-of-Law Provisions
For employees who primarily reside and work in California, employers cannot require as a condition of employment any provision that requires adjudication of California claims outside California or deprives the employee of California law's substantive protection (Lab. Code § 925). Such provisions are voidable by the employee, who may then compel California adjudication under California law. The only exception is when the employee was individually represented by legal counsel in negotiating the provision (Lab. Code § 925(e)).
Required Waivers of FEHA or Labor Code Rights
Employers cannot require applicants or employees to waive any right, forum, or procedure for a Fair Employment and Housing Act (FEHA) or Labor Code violation as a condition of employment, continued employment, or benefits (Lab. Code § 432.6(a)). This prohibition does not invalidate arbitration agreements otherwise enforceable under the Federal Arbitration Act (Lab. Code § 432.6(f)). The Ninth Circuit has held the FAA preempts California's attempt to restrict arbitration agreement formation (Chamber of Commerce v. Bonta, 62 F.4th 473 (9th Cir. 2023)).
Overbroad Confidentiality or Non-Disparagement Clauses
Under the "Silenced No More Act" (Gov. Code § 12964.5), employers cannot require employees to sign agreements denying the right to disclose information about unlawful workplace acts. Any nondisparagement or confidentiality provision restricting discussion of workplace conditions must include this mandatory disclaimer: "Nothing in this agreement prevents you from discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that you have reason to believe is unlawful" (Gov. Code § 12964.5(a)(1)(B)(ii)). Non-compliant provisions are unenforceable as contrary to public policy (Gov. Code § 12964.5(a)(2)).
Is a signed offer letter legally binding in California?
An offer letter can support claims for breach of contract or promissory estoppel (Thompson v. Oracle Corp., No. 3:21-cv-00026 (N.D. Cal.)). California follows the at-will employment presumption: employment with no specified term may be terminated by either party with notice (Lab. Code § 2922). Employers may generally modify at-will terms unilaterally, provided the change does not violate a statute or breach an express or implied contract (Gurpreet Singh v. Southland Stone, U.S.A., Inc., 186 Cal. App. 4th 338 (2010)).
What are the rules for conditional offers and medical exams?
California permits conditional offers contingent on background checks or medical examinations, with specific procedural requirements:
| Requirement | California Rule | Federal Baseline |
|---|---|---|
| Medical exam timing | Only after conditional offer (Gov. Code § 12940(e)(1)) | Same (ADA) |
| Employer size threshold | 5+ employees (FEHA) | 15+ employees (ADA) |
| Exam cost payment | Employer must pay all costs (Cal. Code Regs., tit. 2, § 11069(d)(8)) | No federal requirement |
| Independent medical opinion | Employee may submit before final disqualification (Cal. Code Regs., tit. 2, § 11071(b)(2)) | Not required |
| Uniform application | Required of all entering employees in same job classification | Same |
Post-offer medical examinations must be job-related and consistent with business necessity (Gov. Code § 12940(e)(3)(A)). Employers may withdraw offers only if the applicant cannot perform essential duties with or without reasonable accommodation or would pose a direct threat to health or safety (Cal. Code Regs., tit. 2, § 11071(c)).
Does California have stricter offer letter rules than other states?
Yes. California imposes numerous requirements that exceed the federal baseline.
| Feature | California | Federal/National Baseline |
|---|---|---|
| Hiring notice | Mandatory detailed written notice with 10+ specific categories (Lab. Code § 2810.5) | No general federal requirement |
| Pay transparency | Pay scale disclosure upon request; mandatory in job postings for 15+ employees; salary history prohibition (Lab. Code § 432.3) | No federal pay posting requirement; salary history generally permitted |
| Noncompete clauses | Per se void in employment, regardless of reasonableness (Bus. & Prof. Code § 16600) | Generally enforceable if reasonable |
| Forum/choice-of-law | Cannot require out-of-state adjudication or non-California law for California-based employees (Lab. Code § 925) | Generally enforceable under The Bremen and Atlantic Marine standards |
| Paid sick leave | Mandatory accrual (1 hour per 30 hours); 40-hour/5-day use cap; broad family definition (Lab. Code §§ 245–249) | No federal paid sick leave mandate |
| Medical exam protections | Broader coverage (5+ employees); employer pays costs; right to independent opinion (Gov. Code § 12940(e)) | ADA applies to 15+ employees; no cost payment requirement |
| Commission agreements | Written contract required with specific content and formalities (Lab. Code § 2751) | No federal requirement |
| Arbitration restrictions | Armendariz requirements; fee default rules; attempted prohibition on required waivers (federally preempted) | FAA strongly favors arbitration |
| "Silenced No More" protections | Mandatory disclaimer required; restrictions on unlawful workplace act disclosures prohibited (Gov. Code § 12964.5) | No direct federal equivalent |
What are the commission agreement requirements?
For commission-based compensation, California requires a written contract setting forth the method by which commissions are computed and paid (Lab. Code § 2751(a)). The employer must provide a signed copy to the employee and obtain a signed receipt. If the contract expires and work continues, the terms are presumed to remain in full force until superseded or terminated (Lab. Code § 2751(b)).
What are the arbitration agreement rules?
To be enforceable in California, arbitration agreements must satisfy five minimum requirements from Armendariz v. Foundation Health Psychcare Servs., Inc., 24 Cal. 4th 83 (2000): neutral arbitrator, adequate discovery, written award permitting limited judicial review, availability of all court remedies, and no employee cost-shifting.
Under CCP §§ 1281.97, 1281.98, if the employer (as "drafting party") fails to pay required arbitration fees within 30 days, it is deemed in material breach and waives the right to compel arbitration. The employee may unilaterally withdraw the claim to court, and the court must impose sanctions. However, under Hohenshelt v. Superior Court (Cal. Aug. 11, 2025), equitable relief from forfeiture is available for good-faith mistakes or excusable neglect.

What are the background check and privacy requirements?
California's Investigative Consumer Reporting Agencies Act (ICRAA) imposes requirements beyond federal FCRA. Employers must provide a standalone disclosure before procuring an investigative consumer report, with specific content including a summary of rights under Civ. Code § 1786.22 (Civ. Code § 1786.16(a)(2)). Written authorization is required. A copy of the report must be provided within three business days if requested. Statutory damages of $10,000 or actual damages, whichever is greater, apply for violations (Civ. Code § 1786.50).
Employers are generally prohibited from using consumer credit reports unless the position falls into specific categories like managerial positions or law enforcement (Lab. Code § 1024.5).
Under the California Consumer Privacy Act, businesses must provide a Notice at Collection at or before collecting personal information from applicants and employees, including categories of data collected, purposes of use, and retention periods (Civ. Code § 1798.100).
