For years, employers and employees alike have misunderstood the legality of non-compete agreements in California. While non-compete clauses remain enforceable in many states under certain circumstances, California has long maintained one of the strongest public policies in the nation favoring employee mobility and open competition.
Recent legislation, including Senate Bill 699 (SB 699) and Assembly Bill 1076 (AB 1076), has further strengthened California's prohibition against non-compete agreements and significantly increased potential liability for employers attempting to enforce unlawful restrictions.
So, are non-compete agreements enforceable in California? What legal options do employers have to protect their business interests? And what should employees do if they are threatened with enforcement of a non-compete clause?
This article provides an overview of California law and practical guidance for both employers and employees.
What Is a Non-Compete Agreement?
A non-compete agreement is a contractual provision that restricts an employee from working for a competitor, starting a competing business, or engaging in similar employment after leaving a company.
In many states, courts may enforce non-compete agreements if they are reasonable in duration, geographic scope, and business purpose. California, however, takes a fundamentally different approach.
Under California Business and Professions Code §16600:
"Except as provided in this chapter, every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void."
As a general rule, California prohibits employers from restricting an individual's right to pursue lawful employment.
Why Are Non-Compete Agreements Generally Unenforceable in California?
California courts have consistently held that employee mobility is essential to innovation, economic growth, and fair competition.
In the landmark case of Edwards v. Arthur Andersen LLP (2008), the California Supreme Court rejected attempts to enforce narrowly tailored non-compete agreements and declined to adopt the so-called "blue-pencil doctrine," which allows courts in some states to modify overly broad restrictions.
As a result, California courts generally will not rewrite or narrow an unlawful non-compete clause. Instead, the provision is typically deemed void and unenforceable.
Key California Principles
- Non-compete agreements are generally void unless a statutory exception applies.
- Restricting an employee's ability to work for a competitor is usually unlawful.
- Employers may face legal liability for attempting to enforce invalid non-compete provisions.
- Out-of-state non-compete agreements often cannot be enforced against employees working in California.
- Confidentiality agreements cannot be used as disguised non-compete restrictions.
California's Public Policy Favoring Employee Mobility
California's prohibition on non-compete agreements is rooted in a strong public policy supporting:
Employee Freedom
Workers should be free to pursue better employment opportunities and advance their careers without undue restrictions.
Open Competition
Healthy competition encourages innovation, lowers costs, and benefits consumers and businesses alike.
Entrepreneurship and Innovation
California's technology, healthcare, entertainment, and professional services sectors have flourished in part because talented professionals can move freely between companies and launch new ventures.
Fair Labor Practices
The law prevents employers from using restrictive covenants to trap workers in unfavorable employment conditions.
Are There Any Exceptions?
Although California generally prohibits non-compete agreements, a few narrow statutory exceptions exist under Business and Professions Code §§16601–16602.5.
1. Sale of a Business or Goodwill
A seller who transfers ownership of a business may agree not to compete with the buyer within a reasonable geographic area and for a reasonable period of time.
Requirements typically include:
- A legitimate sale of business ownership or goodwill
- Reasonable restrictions
- Application only to the selling party
2. Dissolution of Partnerships or LLCs
Partners or LLC members may agree to certain restrictions following the dissolution of a business entity.
The restrictions must generally:
- Relate directly to the dissolution
- Be reasonable in scope
- Apply only to former owners or members
3. Protection of Legitimate Trade Secrets
California law allows employers to protect bona fide trade secrets through carefully drafted confidentiality agreements.
However, employers cannot use confidentiality provisions as a backdoor method of preventing lawful competition.
Trade secret protection is governed by the California Uniform Trade Secrets Act (CUTSA) and applies only to information that meets the legal definition of a trade secret.
Employer Perspective: How Can Businesses Protect Their Interests Legally?
Many employers mistakenly believe that non-compete agreements are necessary to protect their business. In reality, California offers several lawful alternatives.
Effective Alternatives to Non-Compete Agreements
Confidentiality Agreements
Employers may require employees to safeguard proprietary information, trade secrets, client data, and confidential business records.
Trade Secret Protection Programs
Implementing access controls, cybersecurity measures, confidentiality training, and exit procedures can significantly reduce risk.
Tailored Customer Protection Measures
Employers may protect legitimate confidential customer information when properly structured and compliant with California law.
Strong Internal Policies
Clear employment policies, confidentiality protocols, and information security practices often provide greater protection than unenforceable restrictive covenants.
As attorney Paul P. Cheng explains:
"California employers should focus on protecting trade secrets and proprietary information rather than attempting to restrict employee mobility. Businesses that rely on unlawful non-compete agreements may expose themselves to significant legal liability."
Employee Perspective: What Should You Do If an Employer Threatens to Enforce a Non-Compete Agreement?
Employees often receive demand letters, threats of litigation, or warnings that they cannot work for a competitor after leaving a job.
In many cases, those threats are not supported by California law.
Practical Steps Employees Should Consider
Review the Agreement Carefully
Determine whether California law applies and whether the restriction falls within a statutory exception.
Preserve Evidence
Keep copies of employment agreements, separation documents, emails, demand letters, and communications regarding the restriction.
Seek Legal Counsel Promptly
An experienced employment attorney can evaluate the enforceability of the provision and identify available remedies.
Consider Declaratory Relief
Employees may seek a court order declaring an unlawful non-compete agreement void and unenforceable.
Evaluate Potential Claims
Depending on the circumstances, employees may have claims arising from unfair business practices, retaliation, or other unlawful conduct.
Common Non-Compete Disputes We See
At Law Offices of Paul P. Cheng & Associates, we frequently encounter disputes involving:
- Out-of-state employers attempting to enforce non-compete agreements against California employees
- Overly broad confidentiality agreements functioning as de facto non-compete clauses
- Threatened injunctions designed to prevent employees from accepting new employment
- Retaliation against employees who challenge unlawful restrictions
- Business owners seeking guidance on lawful methods of protecting trade secrets
Recent Changes Under SB 699 and AB 1076
California lawmakers recently strengthened employee protections through SB 699 and AB 1076.
These laws increase employer compliance obligations and reinforce California's longstanding prohibition against non-compete agreements, including certain attempts by out-of-state employers to impose restrictions on California workers.
Businesses should review existing employment agreements and onboarding documents to ensure compliance with current California law.
Final Thoughts
Whether you are an employer seeking to protect valuable business assets or an employee facing restrictions on your career opportunities, understanding California's non-compete laws is critical.
Attempting to enforce an unlawful non-compete agreement can expose employers to significant legal risk. Likewise, employees should not assume that a restrictive covenant automatically prevents them from pursuing new opportunities.
Early legal guidance can often prevent costly litigation and protect your rights.
