Moonlighting Clauses: Can My Employer Ban a Second Job?

Why employers include them

Employers usually have three concerns: that you will work for a competitor, that you will misuse their confidential information, and that outside work will affect your performance or availability. The first two are strong interests the law recognizes. The third is weaker, and a clause resting only on it is easier to challenge.

The duty of loyalty applies anyway

Even with no clause at all, employees generally owe a duty of loyalty while employed. That means you cannot work for a direct competitor, divert your employer’s business opportunities to yourself, or use its confidential information for outside work. A moonlighting clause that restates these limits adds little and is usually enforceable.

Where state law protects off-duty activity

Several states restrict how far employers can control what you do on your own time. California protects lawful conduct occurring during nonworking hours away from the employer’s premises. New York protects legal recreational and other activities outside working hours and off premises, subject to exceptions for material conflicts of interest. Colorado protects lawful off-duty activities, with exceptions tied to the employer’s legitimate business needs.

None of these protect competing work or genuine conflicts of interest. What they do weaken is a blanket rule that you may not do any other paid work at all, regardless of whether it affects your employer.

Clauses that are usually fine

These are normal and generally enforceable:

• No work for competitors or customers while employed.
• No use of company time, equipment or information for outside work.
• Disclosure of outside work that could create a conflict of interest.
• Limits for senior roles with genuine exclusivity obligations.

Clauses worth pushing back on

Be cautious if the clause includes any of these:

• A ban on any outside work, of any kind, whether or not it relates to the job.
• Permission required for unpaid, creative or volunteer activities.
• A restriction that continues after you leave (that is a non-compete, and different rules apply).
• An IP clause claiming ownership of whatever your side work produces.

A worked example

Nina works full-time as a graphic designer for a retailer in New York and does freelance illustration for children’s book publishers on weekends. Her contract prohibits “any outside employment without prior written approval”.

Her freelance illustration does not compete with a retailer, uses her own equipment, and happens outside working hours. New York protects legal activities conducted off premises and outside working hours, subject to exceptions such as material conflicts of interest. A blanket ban on unrelated freelance work is therefore on weak footing. The simplest path is to disclose the work and ask for written approval, which most employers grant for work that does not compete or conflict.

Gig work and part-time roles

The rise of gig and platform work has made moonlighting questions more common. Driving for a rideshare service, delivering food, or selling on a marketplace rarely competes with a salaried job, and employers usually have little legitimate interest in restricting it. The exception is where the outside work creates a real conflict, uses confidential information, or affects your availability during working hours you are paid for.

Signs a moonlighting clause is reasonable

• It is limited to competing work or genuine conflicts of interest.
• It allows outside work with notice or approval that will not be unreasonably withheld.
• It ends when your employment ends.
• It does not claim ownership of what your outside work produces.

Sample wording you can send

“I currently do freelance [type of work], which does not compete with the company. Could we limit the outside-work clause in section X to competing work and conflicts of interest, and confirm approval of my existing freelance work in writing?”

Common mistakes

• Starting outside work without checking the contract.
• Using company equipment, software licenses or time for outside work.
• Assuming off-duty conduct laws cover competing work.
• Ignoring how the IP clause applies to what you create outside work.

Holding two full-time remote jobs

Some remote workers hold two full-time jobs at once without telling either employer. That usually breaches exclusivity or conflict-of-interest clauses in both contracts, and it can be grounds for termination for cause. Where working hours overlap and time is recorded or billed to both employers, it can create more serious problems. If you want to combine two roles, the safe route is disclosure and written approval, or restructuring one role as part-time or consulting work with its own clear terms.

Public sector and regulated roles

Different rules often apply in government employment and regulated industries. Government employees commonly need ethics approval for outside work, and roles in finance, healthcare and law may carry regulatory restrictions on outside business activities. In these roles, check both your contract and any sector rules before taking on outside work.

What happens if you breach the clause

The usual consequence is disciplinary action, up to termination. If the outside work involved competing, using confidential information, or diverting business, the employer may also have a claim for any losses and, in some cases, for profits you made. Where the clause is overbroad and the outside work is lawful and unrelated, the practical risk is mainly to your job rather than a damages claim, but losing the job is often the cost that matters.

Quick checklist

• Read whether the clause bans all outside work or only competing work.
• Check whether your state protects lawful off-duty activity.
• Disclose existing outside work before signing.
• Get approval for outside work in writing.
• Keep outside work off company time, devices and systems.
• Read the IP assignment clause alongside the moonlighting clause.

Key terms explained

These are the terms you are most likely to meet in the clause itself and in any correspondence about it, explained in plain English so you can read your own contract with confidence.

• Moonlighting: working a second job or doing outside paid work while employed.
• Exclusivity clause: a term requiring you to work only for one employer.
• Conflict of interest: outside activity that competes with or could harm the employer’s interests.
• Duty of loyalty: an employee’s obligation not to compete with or act against the employer while employed.
• Off-duty conduct law: a state law protecting lawful activities outside working hours.
• Overemployment: holding two full-time jobs at once, usually without either employer’s knowledge.
• Outside activity approval: written permission from an employer for specific outside work.

If your employer finds out about outside work

If an employer discovers outside work it did not approve, the conversation usually starts with a request to explain it. Be factual: what the work is, when you do it, and why it does not compete or conflict. Offering to formalize approval, or to adjust the work to remove any conflict, often resolves the matter. Denying work that can be verified tends to turn a manageable policy question into a question of honesty, which is much harder to recover from.

How to handle it

If you already have outside work, disclose it before you sign and ask for it to be approved in writing. If you plan to start something, ask for the clause to be limited to competing work and genuine conflicts of interest. Read the moonlighting clause alongside the IP assignment clause, because the combination is what decides whether your side income, and anything it produces, stays yours. ClauseAudit reads both together and flags where they overreach.
