California Employment Contracts: Complete Guide to Your Rights

California employment contracts work differently than contracts in almost any other state. California law gives workers exceptional protection against restrictive contract terms that would be legal elsewhere. Non-compete agreements are banned. Non-solicitation clauses face strict limits. Arbitration agreements must meet high fairness standards.

This comprehensive guide explains what employment contracts are legal in California, which provisions are void, and how to protect your rights when signing any employment agreement.

What Are Employment Contracts?

An employment contract is any agreement between you and your employer that defines the terms of your working relationship. These contracts can be written, oral, or implied through employer policies and conduct.

Employment contracts may cover:

Most California workers are employed “at-will,” meaning either party can end the relationship at any time for any legal reason. However, even at-will employees often sign contracts containing specific restrictions like confidentiality clauses or arbitration agreements.

California’s Unique Employment Contract Protections

California provides stronger employee protections than any other state. While most states allow employers to restrict where you can work after leaving a job, California takes the opposite approach. The state prioritizes worker mobility and economic freedom.

Several key laws protect California employees:

Business & Professions Code Section 16600 declares non-compete agreements void except in three narrow situations involving business sales and partnership dissolutions. This statute reflects California’s fundamental policy that workers should be free to pursue their livelihood without restriction.

Labor Code Section 2870 limits employer ownership of employee inventions. Your employer cannot claim inventions you develop on your own time using your own resources, unless they relate directly to your employer’s business or result from work you did for them.

Labor Code Section 1102.5 protects whistleblowers from retaliation. No employment contract can prevent you from reporting suspected legal violations to government authorities.

Senate Bill 331 (effective January 1, 2022) restricts non-disclosure agreements in harassment, discrimination, and retaliation settlements. You cannot be silenced about harassment as a condition of settlement.

Assembly Bill 51 (effective January 1, 2020) prohibits employers from requiring employees to sign arbitration agreements as a condition of employment, though this law faces ongoing legal challenges.

California courts consistently interpret these laws broadly to favor employee rights over employer interests. When a contract provision conflicts with California’s public policy protecting workers, courts void that provision.

Types of Employment Contracts in California

Written Employment Contracts

Written contracts spell out specific terms of employment in a signed document. These are most common for executive positions, highly specialized roles, or unionized workplaces.

A written employment contract might specify:

Written contracts override the general at-will employment presumption. If your contract says you can only be fired “for cause,” your employer must prove good reason to terminate you.

Oral Contracts

California recognizes oral employment contracts, though proving their terms can be difficult. If your employer makes specific promises during hiring about job security, compensation, or other terms, those promises may be legally enforceable.

Example: Your future boss tells you during the hiring process, “We’re offering you a three-year guaranteed position.” This oral promise could modify your at-will status even without a written contract.

Document verbal promises by following up with an email confirming what you discussed. This creates written evidence of oral agreements.

Implied Contracts

Even without written or oral agreements, California law recognizes implied contracts formed through employer conduct and policies. Your employee handbook can create binding obligations on your employer.

Courts look at several factors to determine if an implied contract exists:

Example: Your employee handbook states that employees will only be terminated after written warnings and an opportunity to improve. Your employer must follow this procedure even though you never signed a contract saying so.

Collective Bargaining Agreements

If you belong to a union, your employment terms are governed by a collective bargaining agreement negotiated between your union and employer. These contracts typically provide:

Collective bargaining agreements override individual employment contracts and at-will employment. Union members have significantly stronger job protections than non-union workers.

Common Contract Clauses and Their Enforceability

Non-Compete Agreements

Legal Status: VOID in California

Non-compete agreements attempt to prevent you from working for competitors or starting a competing business after leaving your job. California Business & Professions Code Section 16600 declares these agreements void with only three narrow exceptions.

The statute states: “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.”

California courts interpret this language strictly. A non-compete is void regardless of:

The three exceptions allowing non-competes:

  1. Sale of business goodwill (when you sell your ownership interest in a company)
  2. Dissolution of a partnership (when partners separate)
  3. Dissolution of an LLC (when members separate)

Unless you are selling your business or dissolving a partnership, any non-compete agreement is unenforceable against you in California.

Non-Solicitation Agreements

Legal Status: Limited enforceability

Non-solicitation agreements attempt to prevent you from recruiting former colleagues or doing business with former clients. Unlike non-competes, these agreements are not automatically void, but California law severely restricts them.

Customer non-solicitation: California courts generally refuse to enforce broad bans on contacting former customers. You can work with customers you knew through general knowledge or public sources. Your employer can only restrict use of confidential trade secret customer information.

The key case is Edwards v. Arthur Andersen LLP (2008), where the California Supreme Court held that non-solicitation provisions that operate as non-competes are void under Section 16600.

Employee non-solicitation: Courts scrutinize these clauses carefully. You have a right to tell former colleagues about job opportunities. Overly broad restrictions on recruiting former coworkers are unenforceable.

A non-solicitation clause may be enforceable only if it:

Confidentiality Agreements and NDAs

Legal Status: Enforceable with significant limits

Confidentiality agreements and non-disclosure agreements (NDAs) require you to keep certain employer information secret. California generally enforces these agreements when they protect legitimate trade secrets.

Your employer can require confidentiality for:

Your employer cannot silence you about:

Labor Code Section 1102.5 protects whistleblowers. No NDA can prevent you from reporting suspected violations to government authorities or law enforcement.

Senate Bill 331 (effective January 2022) prohibits settlement agreements that prevent disclosure of harassment, discrimination, or retaliation claims. You cannot be required to keep silent about workplace harassment as a condition of receiving settlement money.

Arbitration Agreements

Legal Status: Enforceable if procedurally and substantively fair

Many employers require employees to sign arbitration agreements forcing workplace disputes into private arbitration rather than court. The Federal Arbitration Act generally makes these agreements enforceable, but California applies strict fairness standards.

California courts will void an arbitration agreement that is “unconscionable”—either procedurally unfair (how you were pressured to sign) or substantively unfair (the terms themselves).

An arbitration agreement may be unenforceable if:

Important exception – PAGA claims: You cannot be forced to arbitrate Private Attorneys General Act (PAGA) claims. These representative actions belong to the state, not individual workers. Recent Supreme Court decisions have addressed PAGA arbitrability, but key protections remain.

Assembly Bill 51 note: AB 51 attempted to prohibit mandatory arbitration agreements as a condition of employment, but federal courts have blocked enforcement, finding it preempted by the Federal Arbitration Act. The legal landscape continues to evolve.

Severance Agreements

Legal Status: Enforceable with mandatory protections

Severance agreements offer you payment or benefits in exchange for waiving your right to sue your employer. These agreements are legal but cannot waive all of your rights.

You cannot waive:

You can waive:

Requirements for valid severance agreements:

California Labor Code Section 206.5 prohibits requiring employees to sign releases for wages already earned. You cannot be forced to waive your right to wages you have already worked for.

Employee Handbooks

Legal Status: Can create implied contracts

Employee handbooks are not always contracts, but California’s implied contract doctrine means they can create binding obligations on your employer.

When a handbook creates enforceable obligations:

When a handbook does not create a contract:

If your handbook promises you can only be fired “for cause” after warnings and a progressive discipline process, your employer must follow those procedures even though you never signed a written contract.

California courts have awarded substantial damages to employees terminated in violation of handbook procedures.

What Makes a Contract Unenforceable in California

California courts will refuse to enforce employment contract provisions that violate public policy or are unconscionable.

Violation of Public Policy

A contract provision violates public policy if it:

California’s strong public policies favor worker mobility, workplace safety, and the right to report legal violations. Any contract that conflicts with these policies is void.

Unconscionability

A contract is unconscionable if it is extremely one-sided or unfair. California courts examine both procedural unconscionability (unfair bargaining process) and substantive unconscionability (unfair terms).

Procedural unconscionability factors:

Substantive unconscionability factors:

Sophisticated courts recognize the inherent inequality in the employment relationship. Even though you “voluntarily” sign employment contracts, courts understand that refusing to sign usually means losing your job opportunity.

Lack of Consideration

For a contract to be valid, both parties must receive something of value (consideration). If your employer asks you to sign new restrictions after you are already working, they must give you something new in exchange.

Adequate consideration includes:

Inadequate consideration:

If you are asked to sign new employment restrictions after starting work, consult an attorney before signing. You may have leverage to negotiate or refuse.

Your Rights When Signing Employment Contracts

California law provides you with specific protections when entering employment contracts:

Right to Review and Consider

While California law does not always require specific review periods (except for certain severance agreements), best practices suggest you should:

Employers who pressure immediate signing or refuse to answer questions raise red flags. Legitimate employers understand that employees need time to review important legal documents.

Right to Consult an Attorney

You always have the right to consult an attorney before signing any employment contract. For executive positions, contracts with equity compensation, or agreements with restrictive covenants, paying for legal review is a wise investment.

Many employment attorneys offer flat-fee contract reviews. One hour of attorney time can save you years of legal problems and lost income.

Right to Negotiate

Employment contracts are negotiable, especially for professional and executive positions. You can:

You have the most leverage before starting work. Once employed, you have less ability to negotiate contract changes. Never assume contract terms are final.

Right to Refuse

You can refuse to sign an employment contract, though your employer can then refuse to hire you (unless the contract contains illegal provisions). Weigh the costs and benefits carefully.

If an employer asks you to sign new restrictions after you are already working, refusing may trigger termination. However, if the new restrictions are illegal (like a non-compete), you may have a wrongful termination claim if fired for refusing.

What to Do If Your Employer Violates Your Contract

If your employer breaches your employment contract, you have several options:

Document the Violation

Gather evidence of the breach:

Attempt Internal Resolution

Consider addressing the issue with:

Document all communications. Follow up conversations with emails confirming what was discussed. This creates a written record and demonstrates your good faith efforts to resolve the problem.

File Government Complaints

Depending on the violation, you may file complaints with:

Government agencies investigate at no cost to you and may pursue your case or issue a right-to-sue letter.

Consult an Employment Attorney

An employment attorney can:

Many employment attorneys work on contingency, meaning you pay nothing unless you recover money. Most offer free initial consultations.

Consider Litigation

If other approaches fail, you may need to file a lawsuit for breach of contract. Potential remedies include:

The statute of limitations for breach of written employment contracts is four years. For oral contracts, it is two years. Do not wait too long to protect your rights.

California vs. Other States: How Contract Laws Differ

California’s employment contract laws are among the most employee-friendly in the nation. Here is how California compares to other major states:

State Non-Compete Enforcement Key Differences
California VOID except 3 narrow exceptions Strongest worker protection; employee mobility prioritized
Texas Enforceable if reasonable Common in tech/sales; must be ancillary to employment agreement
New York Enforceable if reasonable Recent reforms; banned for employees under $1 million in revenue threshold
Florida Enforceable with statutory presumptions Employer-friendly; 6-month restriction presumed reasonable
Massachusetts Limited enforceability Capped at 12 months; must pay 50% of salary during restriction
Washington Limited enforceability Banned for workers earning under ~$116,593 (2025)
Illinois Limited enforceability Must pay equivalent of base salary during restriction
North Dakota VOID Similar to California
Oklahoma Very limited Only enforceable to protect trade secrets

Why this matters: If you work in California, you have stronger protections than workers almost anywhere else. If you signed a non-compete in another state and now work in California, California law may apply to void the restriction.

However, if you leave California to work elsewhere, the non-compete may become enforceable depending on where you work and where the contract says the law applies.

Frequently Asked Questions

Can my California employer make me sign a non-compete agreement?

Your employer can ask you to sign a non-compete, but the agreement is void under Business & Professions Code Section 16600. Even if you sign voluntarily, the non-compete is not enforceable except in three narrow situations involving business sales and partnership dissolutions. You can work for competitors without legal consequences.

What happens if I signed a non-compete in another state and now work in California?

California courts frequently apply California law to void non-competes even when signed elsewhere, especially if you now work in California. The analysis depends on where you work, where you signed the contract, and choice-of-law provisions. California’s strong public policy against non-competes often prevails. Consult an employment attorney to review your specific situation.

Can my employer stop me from recruiting my former coworkers?

California limits non-solicitation agreements. You can tell former colleagues about job opportunities. Your employer can only restrict use of confidential trade secret information to recruit. Broad bans on contacting former coworkers are generally unenforceable under Edwards v. Arthur Andersen.

Are arbitration agreements enforceable in California?

Yes, if they meet high fairness standards. California courts will void arbitration agreements that are procedurally or substantively unconscionable. The employer must pay arbitration costs, preserve your discovery rights, and not unfairly limit remedies. You cannot be forced to arbitrate PAGA representative claims even with an arbitration agreement.

Can I be fired for refusing to sign a confidentiality agreement?

California is an at-will employment state, so your employer can generally fire you for refusing to sign. However, if the NDA contains illegal provisions (preventing you from reporting illegal conduct), you may have a wrongful termination claim. If the NDA is required after you are hired with no additional benefit to you, the lack of consideration may make it unenforceable.

Next Steps: Protecting Your Rights

If you are facing an employment contract issue:

  1. Read your contract carefully – Identify all restrictive provisions
  2. Document everything – Save all agreements, emails, and communications
  3. Know California law – Understand what provisions are enforceable
  4. Consult an attorney – Get professional advice before making major decisions
  5. Do not be intimidated – Many employer threats about contracts are legally baseless

California law strongly protects your right to work and earn a living in your chosen profession. Do not let an employer use illegal or unenforceable contract provisions to limit your career opportunities.
