Recent amendments (2022–2025) to the PDPA and Trade Secrets Act have expanded employer obligations and penalties.

Key updates include:

  • Mandatory breach notifications to the regulator within 72 hours under PDPA.
  • Supreme Court rulings confirming that immediate termination is justifiable for material breaches.

Damages and Penalties Employers Can Pursue

Employers facing an employee confidentiality breach in Thailand can seek a range of remedies designed to address financial, reputational and operational risks.

Common legal remedies include:

  • Compensatory and punitive damages, which may be set by the court or defined in NDAs (often starting at THB 100,000, adjusted case by case)
  • Administrative fines for personal data breaches under the PDPA, reaching up to THB 5 million
  • Potential criminal penalties under the Trade Secrets Act, including imprisonment for intentional or severe cases

Thai courts retain the authority to adjust damages if contract clauses set excessive penalties or conflict with public order. Contractual penalty clauses are enforceable but closely scrutinized.

Relevant court precedents can be found via the Office of the Judiciary.

How Injunctions and Notifications Work After a Breach

When a breach is discovered, employers can:

  • Request emergency and permanent injunctions to immediately stop further unauthorized disclosure
  • Fulfill mandatory PDPA notification duties by informing Thailand’s PDPA regulator within 72 hours, as well as affected individuals if high risks are present

Acting quickly and using all available remedies shows partners and regulators that your organization prioritizes confidentiality and legal compliance.

Employer Actions After a Confidentiality Breach

Investigating and Responding to a Suspected Breach

When an employee confidentiality breach is suspected in Thailand, immediate and thorough action is essential.

Employers should implement an investigation framework that includes:

  • Collecting evidence quickly (emails, digital files, devices)
  • Using digital forensics experts to track data movement
  • Documenting all findings to maintain clear chain of custody

Disciplinary steps must also observe legal rights:

  • Conduct confidential interviews with employees involved
  • Ensure all disciplinary processes comply with Thai labor law

Prompt action helps preserve legal options and demonstrates employer diligence in safeguarding business interests.

Filing Claims and Involving Authorities

Employers can pursue legal remedies through these formal channels:

  • File civil claims for damages under contract or tort
  • Submit criminal complaints if trade secrets or PDPA breaches are involved
  • Request immediate injunctions to stop further disclosures

Coordination may include:

  • Notifying Thailand’s PDPA regulator within 72 hours for personal data breaches
  • Engaging law enforcement where appropriate

Alternative processes also include negotiation, mediation, or formal litigation.

A structured breach response ensures maximum legal protection and clear evidence chains. Acting quickly and coordinating with authorities can prevent further harm and send a strong message about business confidentiality standards.

  • Employer’s documented consent to disclosure
