Second job: Legal Guidelines and Company Policies
Is It Legal to Work a Second Job in the US?
The short answer: yes, working a second job is legal in the United States. There is no federal law that prevents you from holding multiple jobs. However, just because it's legal doesn't mean your employer can't have something to say about it.
Most US workers are employed "at-will," which means their employer can terminate them for any reason that isn't specifically prohibited by law (such as discrimination). Unless you have an employment contract that limits your employer's right to fire you, you are most likely an at-will employee. That means, in many states, an employer could technically fire you for moonlighting - even if the second job has nothing to do with your primary work. But there are important exceptions and protections that vary by state. Let's break them down.
The term "moonlighting" originally referred to working a second job after hours - literally by the light of the moon. Today it covers any type of additional employment, from side hustles to full-time remote positions.
State Laws That Protect Moonlighters
Not all states give employers free rein. Some states have off-duty conduct laws that prohibit employers from taking action against employees based on their legal activities outside of work. These protections vary widely:
California is one of the most protective states. Under California Labor Code section 96, employers are essentially prohibited from punishing employees who engage in moonlighting in their free time. California also bans most non-compete agreements, making it even harder for employers to restrict outside work.
Washington has a specific anti-moonlighting statute that protects lower-wage workers. Employers cannot restrict employees earning less than twice the state minimum wage - about $33.32 per hour in 2025, or roughly $68,000 per year - from holding an additional job.
Colorado, New York, and North Dakota also have laws that limit employers' ability to punish lawful off-duty activities, though the specifics differ.
However, many states do not have broad off-duty conduct laws. If you work in one of these states, your employer may be free to fire you for working a second job. Before taking a second job, check your state's off-duty conduct laws. If your state doesn't have specific protections, review your employment contract and company handbook carefully.
What Your Employer Can (and Can't) Restrict
Even in protective states, employers retain certain rights. Employers may legally limit the rights of their employees to work a second job, especially if that work substantially interferes with or competes with the duties of their primary job. Here are legitimate reasons your employer can restrict or discipline you for a second job:
Conflict of interest: If your side gig is for a direct competitor or involves soliciting your employer's clients, that's a serious problem. Even without a written agreement, employees owe a duty of loyalty to their employer.
Performance issues: Employers are within their rights to expect that employees show up for work "present, prompt and prepared." If a second job leads to fatigue, missed deadlines, or lower-quality work, your employer has grounds for disciplinary action.
Use of company resources: Using your employer's equipment, software, or confidential data for outside work can result in termination — and potentially even legal action.
Working during your scheduled hours: No employer is required to allow you to perform other work while you're supposed to be on their clock.
Working two full-time remote jobs simultaneously during the same business hours - sometimes called "polyworking" or "overemployment" - carries significant legal risk. If you're billing two employers for the same hours, you could face termination, lawsuits, or even fraud charges.
Non-Compete Agreements: Where Things Stand in 2026
Non-compete clauses are another critical factor. These contractual provisions can restrict your ability to work for competitors, both while employed and after leaving. Here's the current landscape: In September 2025, the FTC formally abandoned its effort to enact a nationwide ban on non-compete agreements. The proposed rule, introduced in 2024, was blocked by federal courts and ultimately dropped under the new administration.
However, the FTC hasn't walked away from the issue entirely. The FTC filed an enforcement action against a pet cremation company for imposing non-compete agreements on nearly 1,800 employees regardless of skill level or job duties. This signals that while blanket bans are off the table, the FTC will still go after companies whose non-competes are considered excessive or anticompetitive.
The practical result is a state-by-state patchwork:
California, Minnesota, North Dakota, and Oklahoma have banned non-competes with employees outright;
Many other states enforce non-competes, but only if they are reasonable in scope, duration, and geography;
A few states don't allow noncompete contracts, but in most states, a court will hold you to the terms of a reasonable noncompete.
Practical Tips for Employees
If you're considering a second job, here's how to protect yourself:
Review your employment agreement: Look for non-compete clauses, exclusivity provisions, and moonlighting policies. Violating contractual obligations could be grounds for termination or even a lawsuit.
Check the company handbook: Many employers require disclosure or approval of outside employment, even if there's no contract clause.
Avoid conflicts of interest: Don't work for competitors, solicit your employer's customers, or use proprietary information in your side work.
Don't overlap hours: Make sure your second job doesn't interfere with your scheduled work time at your primary job.
Report all income to the IRS: The IRS doesn't have a problem with taxpayers working multiple jobs, but it does have a problem with people who fail to report income.
Talk to your employer: Let your workforce know that moonlighting isn't the problem — lying about it is, and could result in the loss of the primary job. Proactive honesty is often the best policy.
What Employers Should Do:
Create a clear conflict of interest policy that specifies what's prohibited and what requires disclosure
Include outside employment provisions in offer letters and employee handbooks
Focus policies on protecting your business interests - not controlling what employees do in their free time
When developing a moonlighting policy, it is not advised to forbid employees from having a second job - such rules are difficult to enforce and may result in the loss of respected employees
Conclusion:
While holding two jobs is often a viable way to enhance income or explore new career opportunities, it comes with significant legal and professional risks. From understanding your employment contract to navigating potential conflicts of interest, careful consideration is required. The legal landscape surrounding moonlighting varies depending on state laws and individual company policies, making it essential for employees to research their rights and obligations fully.
