In today’s data-driven economy, customer information is a critical asset for many businesses. But what happens when an employee resigns—or is terminated—and takes customer data with them? Whether done intentionally or out of negligence, this act can pose serious legal and commercial risks to the company. This article explores the legal implications, real-world challenges, and strategies businesses can adopt to prevent and respond to such situations, particularly in the Vietnamese context.
1. Why This Issue Matters
Customer data often includes sensitive information such as:
– Names, contact details, and purchasing history;
– Pricing agreements or contract terms;
– Notes on preferences, complaints, or internal assessments.
Losing this information—or worse, having it used by a competitor—can result in:
– Loss of clients and revenue;
– Violation of data protection laws;
– Damage to business reputation.
2. Legal Grounds for Action
In Vietnam, several legal frameworks may be invoked when an employee misappropriates customer data:
a. Labor Law Violations
Under the Labour Code 2019, employees have a duty of loyalty and must not disclose trade secrets or confidential information obtained during their employment. Employers may:
– Discipline the employee;
– Seek compensation for damages;
– Include non-disclosure agreements (NDAs) in labor contracts.
b. Intellectual Property and Trade Secrets
According to Law on Intellectual Property, business information can qualify as a trade secret if:
– It is not publicly known;
– It has commercial value;
– The employer has taken reasonable measures to protect it.
Misappropriation of trade secrets may give rise to civil liability or even criminal prosecution under Article 288 of the Penal Code.
c. Data Protection Obligations
While Vietnam’s data protection regulations are still evolving, the Decree No. 13/2023/ND-CP on Personal Data Protection imposes obligations on parties handling personal data, including employees. Unauthorized sharing of customer data could violate these rules and expose both the individual and the company to administrative penalties.
3. Common Scenarios in Practice
– Sales staff leaving to join a competitor, using old contact lists to lure clients away;
– Customer service agents copying CRM databases before resigning;
– Employees forwarding sensitive information to personal emails or cloud accounts.
These actions may not always be discovered immediately—but the damage may already be done.
4. How Businesses Can Protect Themselves
a. Contractual Measures
– Include clear confidentiality clauses in employment contracts;
– Use non-compete and non-solicitation clauses, where legally permitted;
– Require return or deletion of all company data upon termination.
b. Technical Controls
– Restrict access to sensitive data on a need-to-know basis;
– Monitor data transfers and downloads, especially during notice periods;
– Use software to disable or track access to files post-resignation.
c. Exit Procedures
– Conduct exit interviews that reinforce legal obligations;
– Require employees to sign data return confirmations;
– Deactivate access rights immediately upon termination.
5. Responding to a Breach
If an employer suspects that an ex-employee has taken customer data:
– Act quickly to preserve evidence (e.g., email logs, access history);
– Send legal warnings or demand letters;
– Consider civil litigation or criminal complaints, especially if a competitor is involved;
– Notify customers if required under data protection laws.
In some cases, negotiating a resolution or settlement may be faster and more commercially practical than full litigation.
Conclusion
When employees leave with customer data, the consequences can be severe. Vietnamese law offers tools for businesses to protect their interests, but proactive prevention is always better than reactive enforcement. With the right mix of contractual, technical, and legal strategies, companies can reduce the risk of data loss and maintain trust with their clients—even during transitions in their workforce.
