Conducting Trauma-Informed Workplace Investigations from Start to Finish | Part 2

Last week in Part 1 of this two-part blog, we focused on setting the tone for a trauma-informed investigation and supporting participants through the process leading up to and during interviews.

This second part picks up where that leaves off and talks about how to apply a trauma-informed approach when assessing evidence, making findings, and communicating outcomes.

1.  Make findings with an understanding of trauma

A trauma-informed approach is important when weighing and analyzing the evidence and reaching findings. Trauma can affect:

• Memory recall
• Emotional presentation
• Behaviour during interviews

These factors should not be assessed in isolation when considering credibility. Hesitation, lack of eye contact, or emotional responses shouldn’t automatically suggest dishonesty or unreliability. The analysis should:

• Avoid reliance on assumptions about how a person “should” behave
• Focus on the evidence and context
• Be mindful that evidentiary inconsistencies may reflect how traumatic memory is stored and retrieved

Findings should use neutral, plain language that does not assign unnecessary blame or judgment, and avoids inflammatory or editorial wording.

2. An equity and cultural context lens

Just as we all have individual perceptions, we each bring our unique lived experiences to investigations – whether as investigators or parties. Be mindful of unconscious biases and avoid assumptions and stereotypes that can affect the objective assessment of evidence.

When assessing a participant’s evidence, investigators should look through an equity lens and consider:

• Cultural, historical, and gender-related factors that translate into differences in how we each communicate or engage
• Language proficiency or meaning that may have been lost through language barriers or a translator
• The potential impact of past negative experiences with authority
• Power dynamics that may cause hesitation to speak up and fear of retribution

3. Ongoing communication

One of the most important aspects of an investigator’s relationship with participants is trust. Uncertainty, inconsistency, or silence can undermine trust, especially in sensitive investigations. Maintaining regular, clear communication appropriate to the participant’s role in the investigation, and following through on what has been communicated, reduces stress and supports open engagement. This includes:

• Providing updates at reasonable intervals
• Explaining delays
• Being clear about next steps
• Responding to questions in a timely, transparent, and respectful way

4. Communicate findings clearly and respectfully

How and when findings are communicated can have a significant impact on participants. A trauma-informed approach to communicating findings and next steps:

• Is timely
• Provides concise, plain language summaries, avoiding legal jargon
• Clearly states and focuses on the findings, including any laws or policies breached
• Avoids unnecessary recitation of events
• Uses professional and neutral language
• Reiterates confidentiality, no reprisals, and available supports

Often allegations are based on a party’s honestly held perception of events yet the objective evidence does not support their perception. Where findings are not substantiated, it’s helpful to explain that the outcome reflects the available evidence rather than a dismissal of a complainant’s experience or (if applicable) a finding they were untruthful.

5. After the investigation: provide closure and maintain trust

The investigation’s impact does not end with the findings. A trauma-informed approach includes:

• Identifying next steps (e.g., workplace restoration, training, policy review)
• Reinforcing availability of supports
• Considering broader workplace impacts

A well-conducted investigation can strengthen trust in the organization. A poorly conducted one can have the opposite effect, including reduced reporting and diminished confidence in the process. Providing the parties with timely closure and transparency helps maintain trust and signal the organization’s commitment to addressing misconduct revealed by the investigation and preventing future similar behaviour.  

A trauma-informed approach does not replace procedural fairness. It operates alongside it. It’s not about softening the investigation process. It’s about conducting investigations in a way that is fair, structured, and responsive to the parties’ needs and how people experience and communicate trauma. It leads to fairer and more effective investigations – both in process and outcome.
