In most cases, your employer cannot stop you from moonlighting in California. Labor Code Section 96(k) protects lawful off-duty conduct, and Business and Professions Code Section 16600 voids nearly all non-compete agreements. What your employer can do is restrict outside work that creates a genuine conflict of interest, hurts your performance on the primary job, or involves company resources or confidential information.
The Right to Work a Second Job in California
Two Labor Code sections do the heavy lifting. Section 96(k) lets the Labor Commissioner take claims from workers who lost 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 LAB Section 96 A second job is lawful conduct, so punishing you for it, standing alone, falls inside that protection.
Section 98.6 reinforces the same idea by prohibiting retaliation against workers who exercise rights under the Labor Code, including the off-duty conduct right in Section 96(k).2California Legislative Information. California Code LAB Section 98.6 Read together, these statutes require an employer to have a legitimate business reason to act against you over a second job. The bare fact that you work somewhere else on your own time doesn’t clear that bar.
Non-Compete Agreements Won’t Hold You Back
California treats non-competes very differently from most states. Business and Professions Code Section 16600 voids any contract that restrains someone from engaging in a lawful profession, trade, or business, and the statute says so “no matter how narrowly tailored.”3California Legislative Information. California Code BPC Section 16600 If your employment paperwork says you can’t work for competitors or take on side work in the same industry, that language is almost certainly unenforceable.
Two 2024 laws expanded those protections. Section 16600.5, added by SB 699, makes non-competes void regardless of where or when they were signed, so an employer cannot enforce a California-void non-compete against you even if you signed it in another state. It also bars employers from entering into contracts containing non-compete provisions and gives affected workers a right to sue for injunctive relief, actual damages, and attorney’s fees.4California Legislative Information. California Code BPC Section 16600.5
AB 1076 added Section 16600.1, which makes it unlawful to include a non-compete clause in an employment contract and treats a violation as unfair competition under California’s unfair business practices law. Employers were also required to notify current and recent former employees that any existing non-compete clauses in their contracts are void.5California Legislative Information. Assembly Bill 1076
The practical takeaway is simple. A non-compete clause in your California employment agreement has no teeth. You do not need your employer’s permission to work in the same field on your own time. Non-compete rules and moonlighting rules are not the same thing, though, and employers still have legitimate ways to limit specific kinds of outside work.
When Your Employer Can Legitimately Restrict Outside Work
A blanket ban on all outside employment is unlikely to survive scrutiny in California. But an employer doesn’t need a non-compete to restrict specific moonlighting activities, provided the restriction ties to a real business concern rather than a wish to control your personal time. The situations where employers can push back:
- Conflict of interest. Working for a direct competitor, soliciting your primary employer’s clients, or building a competing business on the side. Every employee owes a basic duty of loyalty. This is narrower than a non-compete: you’re not barred from the industry, but you cannot actively undermine your employer’s business while on their payroll.
- Declining job performance. If a second job leaves you too tired to do your work, causes missed shifts, late arrivals, or dropped responsibilities, your employer can address the performance problem. What matters is the tangible impact on your primary job, not the fact that another job exists.
- Misuse of company resources or confidential information. Using company equipment, client lists, trade secrets, or proprietary data for outside work crosses a clear line. So does leveraging relationships or knowledge gained at your primary job to benefit your side work.
- Safety regulations. In industries with federally mandated work-hour limits, a second job that pushes you past those limits is a real problem. Commercial truck driving is the clearest example: property-carrying drivers face strict daily and weekly on-duty caps, and a second driving job that would breach them creates a hazard the employer can act on.6Federal Motor Carrier Safety Administration.

What Company Policies Can and Cannot Require
Many California employers deal with moonlighting through written policies in employee handbooks or employment contracts. A well-drafted policy will not try to ban all outside work. Instead, it defines what the company treats as a conflict of interest, requires you to keep your performance standards, and prohibits using company resources for outside work.
These policies can also require you to disclose outside employment so the employer can evaluate whether a conflict exists. Disclosure requirements are generally enforceable. The distinction that matters is between a policy that says “tell us about your other job so we can assess conflicts” and one that says “you may not work anywhere else.” The first is reasonable. The second is the kind of blanket restriction California law disfavors.
Read your handbook and anything you signed at hire. A policy narrowly focused on conflicts, performance, and resource protection is likely valid. A total ban on outside employment conflicts with Section 96(k) and can be challenged.
What Happens if You Break a Valid Moonlighting Policy
If your employer has a clearly communicated, narrowly tailored moonlighting policy and you violate it, discipline can follow. That ranges from a written warning to suspension to termination, depending on how serious the violation is and your employment history.
California is an at-will employment state. Labor Code Section 2922 says employment with no specified term can be ended by either party at any time.7California Legislative Information. California Code LAB Section 2922 Breaching a legitimate company policy is generally a lawful reason for termination in that framework. The word doing the work is “legitimate.” Firing you for violating a total ban on outside employment when your second job caused no actual conflict or performance problem puts the employer on shaky ground.
What to Do if You Were Fired or Disciplined Over a Second Job
An employer who fires, demotes, or disciplines you for lawful off-duty conduct without a valid business justification may be liable for retaliation. Under Section 98.6, remedies include reinstatement, reimbursement for lost wages and benefits, and a civil penalty of up to $10,000 per violation.2California Legislative Information. California Code LAB Section 98.6 The employer carries the burden of showing the action was based on genuine business needs and not disapproval of your moonlighting.
You can file a retaliation complaint with the California Labor Commissioner’s office. The deadline is one year from the date of the retaliatory action, and you don’t need a Social Security number or photo ID to file.8Department of Industrial Relations. How to File a Retaliation/Discrimination Complaint A private lawsuit is another option. If you miss the one-year window with the Labor Commissioner, talk to an attorney about a private action, because the court deadline may differ.
If your employer tried to enforce a non-compete against you, that is a separate claim under Business and Professions Code Section 16600.5. You can bring a private lawsuit for injunctive relief, actual damages, and attorney’s fees.4California Legislative Information. California Code BPC Section 16600.5
