Why Investigations Matter

-

When misconduct arises, knowing when and how to investigate is critical.

Workplace investigations aren’t just about compliance. They are about protecting people, reputation, and culture.

From harassment to fraud, knowing when and how to investigate can make all the difference.

Ahead of the release of our 2025 APAC Employment Law Guide, Fatim Jumabhoy, Partner and Head of Employment & Workplace Investigations, Asia, shares practical tips to help you:

  • Know when to investigate
  • Plan and conduct fair interviews
  • Protect legal privilege
  • Write strong, defensible reports

These insights are drawn from our experience supporting clients across sectors and from our internal guidance, including culturally informed practices and legal privilege protocols where appropriate.

1 Know when to investigate

Not every complaint needs a formal investigation, but some absolutely do.

Investigate when:

  • Allegations involve serious misconduct (e.g. harassment, serious breaches of policy & systemic issues)
  • The matter could attract media or regulator attention
  • Senior individuals are involved
  • There’s a risk of legal liability or reputational damage

Don’t ignore red flags. A prompt, fair investigation protects your people, your business, and its culture.

“Always investigate when the stakes are high.”

2 Plan before you act

A well-planned investigation is fair, efficient, and defensible. Before you begin:

  • Identify the investigator (will you work with an internal team or engage an external provider?)
  • Consider local law requirements (is there a statutory grievance/disciplinary process? Are there work rules?)
  • Define the scope of allegations clearly
  • Map out key witnesses and documents
  • Inform the Respondent of the allegations and evidence against them
  • Provide the Respondent with the opportunity to respond to and defend the allegations.
  • Notify witnesses of the investigation and then schedule interviews (ensuring communications are factual and sensitive)
  • Consider culturally informed practices and legal privilege

Prompt action is important, but fairness needs to be the priority.

“A prompt investigation is a good investigation, but fairness comes first.”

3 Choose the right investigator

The credibility of your investigation depends on who leads it. When deciding whether to engage an external investigator or deploy internal resources you will need to weigh the risks and optics. Either way, your investigator should be:

  • Impartial – no stake in the outcome
  • Experienced – skilled in sensitive interviews and evidence handling
  • Confident – able to manage complex or high-stakes matters and draw factual conclusions based on available evidence.

Internal or external?

  • Internal investigators may be cost-effective and familiar with context (including internal policies and procedures)
  • External investigators offer independence and objectivity. Especially useful for senior-level or reputationally sensitive matters, as well as privilege protection

“Confidence in the investigation depends on the credibility of the investigator”.

4 Get the allegations right

A clear allegation sets the foundation for a fair and focused investigation.

Strong allegations include:

  • Specific details: names, dates, locations
  • Clear description of the conduct
  • Direct relevance to workplace policies or laws

Avoid:

  • Vague or generalised complaints
  • Hearsay or third-hand accounts
  • Allegations that lack factual basis

Why it matters:

Poorly framed allegations can derail the process, confuse witnesses, and undermine outcomes.

“Poorly framed allegations derail investigations.”

5 Protect legal privilege

Legal privilege can ensure that sensitive matters are protected from disclosure but might not be applicable in all cases.

To protect privilege:

  • Involve legal counsel early
  • Ensure communications are for the purpose of legal advice
  • Mark documents as “Privileged and Confidential”
  • Keep investigation materials separate from HR or operational records

Not all investigations are privileged. Be deliberate and document your intent.

“Privilege is a shield, but can only be relied on if used appropriately.”

6 Conduct culturally informed and sensitive interviews

Investigations often involve sensitive topics, how you conduct the interview and process matters.

Best practices:

  • Notify parties in writing and explain the process
  • Offer support persons or EAP referrals
  • Use neutral, non-judgmental language
  • Avoid leading questions or assumptions
  • Be mindful of cultural and psychological safety

Why it matters:

Culturally sensitive approaches build trust, reduce harm, and improve the quality of evidence.

“Respect and impartiality builds trust.”

7 Write a strong report

Your investigation report must be clear, fair, and defensible.

A strong report includes:

  • Clear findings based on evidence
  • Analysis of whether policies or laws were breached
  • Recommendations (where appropriate)
  • A logical structure and neutral tone

Keep in mind:

  • Avoid speculation or emotive language
  • Ensure consistency with interview notes and supporting documents
  • Tailor the report to its audience. HR, legal, or executive

“The key is that the report must be fair, not perfect.”
