Step 1: Gather Evidence of the Conflict
Before acting, confirm the employee’s competitor work with solid evidence to avoid false accusations and ensure a defensible response.
Collect proof discreetly: check LinkedIn for job updates, review work emails (if permitted by policy), or note coworker reports of suspicious activity. Look for deliverables, like reports or designs, appearing in the competitor’s materials. Review the employment contract for clauses banning moonlighting or non-compete agreements, which might prohibit rival work within a set period or region.
Document findings in a Google Docs file: dates, evidence (e.g., “LinkedIn post, May 10, 2025”), and contract clauses. Avoid confronting the employee until your evidence is airtight to prevent denials or cover-ups. The Department of Labor provides labor law insights to guide your review.
Example – Mike’s Startup: Uncovering Moonlighting
Mike, a startup founder, noticed a developer’s code commits slowed. A coworker tipped him off about the developer’s LinkedIn profile listing a rival firm. Mike saved screenshots of the profile and found emails linking the employee to competitor projects, violating a non-compete clause. His evidence gave him leverage for the next steps.
Gathering evidence, as Mike did, ensures you approach the issue with facts, strengthening your position for confrontation or legal action.
Pro Tip – Use Neutral Inquiries
Ask coworkers or IT for general updates, like “Any unusual system activity?” instead of naming the employee. This gathers evidence without raising suspicion or risking defamation claims, keeping your investigation discreet and professional.
Step 2: Consult a Lawyer for Legal Options
Moonlighting for a competitor raises complex legal issues, so consult an employment lawyer to assess risks and remedies before acting.
Hire a lawyer specializing in employment law, sharing your evidence, contract, and state details. They’ll evaluate options: termination for breach, a cease-and-desist letter demanding the employee stop, or trade secret claims if data was shared. Non-compete clauses vary by state—some, like California, restrict them, while others enforce reasonable terms (e.g., 1-year, local ban). Expect $200–$500 for a consultation or $1,000–$3,000 for full support.
The lawyer will flag risks, like wrongful termination lawsuits ($10,000–$50,000 in costs), and recommend steps to minimize liability. Save their advice in a Google Drive folder for reference.
Pro Tip – Request a Case Summary
Ask your lawyer for a written summary ($100–$200 extra) outlining legal options, risks, and recommended actions. Store it in Google Docs to guide your decisions, ensuring you follow a legally sound path that protects your business.
Legal guidance ensures you act within the law, balancing firmness with fairness.
Step 3: Address the Employee Directly
With evidence and legal advice, confront the employee professionally to resolve the issue and protect your business.
Schedule a private meeting with a witness, like an HR rep, and present the evidence calmly (e.g., “Your LinkedIn shows work with [competitor], breaching our contract”). Demand they stop the competitor work immediately or face termination, citing the contract clause. Offer a chance to explain but keep the tone firm and professional—limit the meeting to 15–20 minutes.
Document the discussion: note the date, evidence presented, and any agreements (e.g., “Employee agreed to stop by May 20”). Have them sign a written acknowledgment or follow up with an email summarizing the meeting. Save records in Google Drive.
Example – Laura’s Retail: Resolving the Issue
Laura, a retail manager, found a cashier working for a rival store, breaching a moonlighting clause. In a meeting with her assistant manager present, Laura showed the cashier’s rival schedule and demanded they stop. The cashier agreed, signed a commitment, and Laura avoided termination. Her direct approach resolved the conflict swiftly.
Confronting the employee, as Laura did, clarifies expectations and can preserve the relationship if they comply.
Pro Tip – Draft a Compliance Agreement
Prepare a Google Docs agreement for the employee to sign, stating, “I will cease all work with [competitor] by [date].” This formalizes their commitment and provides a legal record, deterring future violations and supporting termination if breached.
Step 4: Protect Your Business Assets
Whether the employee complies or is terminated, secure your data and operations to prevent leaks or further damage.
Restrict the employee’s access to sensitive systems—remove them from client databases or proprietary software via Okta ($8/user/month). Review data logs for signs of misuse, like downloaded client lists, using IT tools like Splunk ($200/month). If the contract includes a non-disclosure agreement (NDA), enforce it by sending a lawyer-drafted letter ($200–$500) warning of legal action for breaches.

Conduct a security sweep: change passwords, update access codes, and brief staff on data protection without naming the employee. Document actions in Google Drive for audits.
Pro Tip – Conduct a Security Audit
Hire an IT consultant ($500–$1,500) to audit systems for unauthorized access or data leaks within 48 hours of discovery. Use their report to strengthen security, like adding two-factor authentication, ensuring your business stays protected from internal threats.
Securing assets limits the damage from the employee’s actions, safeguarding your competitive edge.
Step 5: Strengthen Employment Policies
A moonlighting incident highlights the need for robust policies to prevent future conflicts of interest.
Update contracts with clear clauses: “No work with competitors during employment” or a non-compete for 1 year post-employment, if enforceable in your state. Add a moonlighting policy requiring written approval for side work. Train staff annually on conflict-of-interest rules, using a 1-hour session with examples like “sharing client data with rivals.” Use BambooHR ($6/employee/month) to track training.
Monitor activity transparently: inform staff that work emails or devices may be checked, per policy. Have a lawyer review contracts ($500–$1,000) for compliance.
Example – Tom’s Agency: New Safeguards
Tom, an agency owner, found a marketer working for a rival, risking client poaching. After resolving it, he added a “no competitor work” clause and mandatory side-work disclosures to contracts. He trained staff yearly and monitored email logs. Tom’s policies deterred future issues, protecting his agency.
Strong policies, like Tom’s, create a culture of loyalty and transparency, reducing risks.
Pro Tip – Implement a Disclosure Form
Create a Google Forms for employees to disclose side work: “List employer, role, hours.” Require annual submissions and review them. This proactive step catches conflicts early, ensuring compliance without micromanaging.
Conclusion
Discovering an employee working for a competitor is a serious breach, but with the right approach, you can protect your business. By gathering evidence, consulting a lawyer, addressing the employee, securing assets, and strengthening policies, you’ll resolve the issue and build resilience. Start today by reviewing your contracts for moonlighting clauses—preparation is your best defense.
