Moonlighting is legal in California for most workers, and the state gives employees some of the strongest off-duty protections in the country. Your employer generally cannot punish you for holding a second job on your own time. The main exceptions involve genuine conflicts of interest, trade secret risks, misuse of company resources, or performance problems that the second job causes at your primary one.
The Laws That Protect Your Right to a Second Job
Two sets of statutes do the heavy lifting.
Labor Code Section 96(k) gives the state Labor Commissioner authority over claims from workers who lose wages after being demoted, suspended, or fired “for lawful conduct occurring during nonworking hours away from the employer’s premises.”1California Legislative Information. California Code Labor Code 96 Holding a second job is lawful off-duty conduct, so an employer who disciplines you only for moonlighting is on the wrong side of this provision.
Section 98.6 is the enforcement half. It bars employers from firing, demoting, or otherwise retaliating against an employee for the conduct described in 96(k). A violation entitles you to reinstatement, reimbursement of lost wages and benefits, and a civil penalty of up to $10,000 per violation.2California Legislative Information. California Code Labor Code 98.6
The second pillar is California’s ban on non-compete agreements. Business and Professions Code Section 16600 voids any contract that restrains someone from engaging in a lawful profession, trade, or business. The statute must be “read broadly” to void any non-compete clause in an employment context, “no matter how narrowly tailored.”3California Legislative Information. California Code Business and Professions Code 16600 An employer cannot hand you a contract that says you won’t work for anyone else and then hold you to it.
SB 699 strengthened this further on January 1, 2024. Under new Section 16600.5, a non-compete is unenforceable regardless of where or when you signed it, including one signed in another state before you moved to California. Employers who enter into or try to enforce a void non-compete commit a civil violation, and you can sue for actual damages, injunctive relief, and attorney’s fees.4California Legislative Information. California Code BPC 16600.5 A companion law, AB 1076, required employers to send written notice by February 14, 2024, telling current and certain former employees that any non-compete clauses in their contracts were void. Failing to send that notice is itself an act of unfair competition.5State of California Department of Justice. Attorney General Bonta Issues Consumer Alert Reminding California Workers Their Rights
Together, these laws mean that a clause limiting your ability to work elsewhere is almost certainly unenforceable. The narrow carveouts involve specific business sale or dissolution scenarios, not ordinary employment.
When Your Employer Can Legally Restrict Outside Work
The right to moonlight is not unlimited. An employer can restrict a second job when it causes concrete harm to the business, as long as the restriction targets the harm rather than the moonlighting itself.
- Conflict of interest. Working for a direct competitor, soliciting your employer’s clients for your side business, or launching a company that competes with your employer are all conflicts an employer can legitimately prohibit. The conflict has to be real, not speculative.
- Trade secret exposure. If the second job creates a genuine risk that you’ll use or reveal confidential information such as customer databases, pricing strategies, or proprietary processes, your employer can restrict it. California’s trade secret protections apply even without a written policy.
- Use of company resources. Doing side work on your employer’s time, with company equipment, or through company software gives your employer valid grounds to step in. Your employer’s resources belong to your employer.
- Job performance problems. An employer cannot dictate what you do on your own time, but it can hold you to performance standards. If moonlighting causes you to show up late, miss shifts, or produce worse work, your employer can address the performance failure. The discipline is for not meeting job requirements, not for the second job itself.
What Makes a Company Moonlighting Policy Enforceable
Many California employers include moonlighting rules in handbooks or employment agreements. A policy is enforceable only when it is narrowly tied to a legitimate business interest. A flat ban on all outside employment is almost certainly illegal under Section 16600 because it functions as a blanket restraint on your right to work.
Enforceable policies tend to do a few things in common. They define a conflict of interest in concrete terms, prohibit using company resources for outside work, and require that outside employment not interfere with job duties. Some require you to disclose a second job so the employer can evaluate potential conflicts. A disclosure requirement is generally permissible as long as the employer uses the information to assess actual conflicts rather than to discourage moonlighting across the board.
Watch for policies that read as backdoor non-competes. A rule banning “outside work in any related industry” or “freelancing using skills you developed here” is likely too broad to survive scrutiny. If the policy looks designed to prevent competition rather than to protect a specific business interest, it probably crosses the line.
If You’re Fired for Moonlighting
California is an at-will state, so your employer can fire you for any lawful reason, and violating a valid moonlighting policy qualifies. Working for a competitor after signing an enforceable conflict-of-interest disclosure, or using company equipment for your side business, can support discipline up to termination. Minor issues typically draw a written warning; working for a direct competitor or misusing trade secrets can support immediate termination.
The discipline has to be for the policy violation, not for moonlighting in general. An employer who fires you because you took a weekend bartending job, with no conflict and no performance issue, has a problem. That kind of termination can support a wrongful termination claim under Section 98.6, which entitles you to reinstatement, lost wages, and a civil penalty of up to $10,000.2California Legislative Information. California Code Labor Code 98.6 If your employer also tried to enforce a non-compete clause against you, you can recover actual damages and attorney’s fees under Section 16600.5.4California Legislative Information. California Code BPC 16600.5
Who Owns What You Create on Your Own Time
If your moonlighting involves creative or technical work, Labor Code Section 2870 limits what your employer can claim. A clause requiring you to assign invention rights to your employer does not reach inventions you develop entirely on your own time, without using the employer’s equipment, supplies, or trade secrets.6California Legislative Information. California Code Labor Code 2870
Two exceptions apply. Your employer can still claim an invention made on your own time if it relates to the employer’s current business or demonstrably anticipated research, or if it resulted from work you performed for the employer. Any contract provision that tries to reach beyond those limits is unenforceable as against public policy.6California Legislative Information.

If Your Side Work Is Freelance or Gig Work
When moonlighting takes the form of freelance work, how you’re classified matters. Under Labor Code Section 2775, anyone providing labor for pay is presumed to be an employee unless the hiring entity can prove all three prongs of the ABC test.7California Legislative Information. California Code Labor Code 2775 The three prongs require that you are free from the hiring entity’s control over how you do the work, that the work falls outside the hiring entity’s usual business, and that you are customarily engaged in an independently established trade or business of the same nature.8California Labor and Workforce Development Agency.

Some licensed professions, creative roles, and business-to-business relationships are carved out of the test, but the default is employee status.
