About the Workshop
​​
Join Mast People Support and EthicsVision for our half day course on Investigation Report Writing in Workplace Investigations.
​
Clear, well-structured investigation reports are critical to fair and defensible workplace investigations. They inform decisions, support HR processes, and are often relied upon by senior leaders, risk committees, and other internal or external stakeholders. Yet many investigators are expected to produce high-quality reports without having received focused, practical training on how to do so.
​
This practical, half-day Investigation Report Writing course is designed for HR and non-HR investigators, case handlers, and investigation leads who are responsible for drafting or reviewing investigation reports. The session focuses on producing reports that are clear, objective, and suitable for different purposes, including HR processes and disciplinaries, governance and risk oversight, and wider stakeholder review.​​​​​
The course is delivered through instructor-led learning, practical exercises, and examples drawn from actual workplace and whistleblowing-related investigations.
​
This event is an in-person event. If you would prefer a bespoke course for your organisation, go to our Work With Us page.

Language, tone and legal considerations
-
Using clear, neutral language for sensitive and high-risk matters
-
Managing confidential and sensitive information appropriately, including whistleblowing disclosures and protected information
-
Awareness of legal, data protection, and disclosure considerations
-
Using appendices, exhibits, and supporting material effectively
Why this matters?
Investigation reports are often the lasting record of how an organisation responded to an issue. Poorly written reports can undermine otherwise sound investigations, create confusion, and expose organisations to challenge.
​
A well-written investigation report:
​
-
Clearly explains what was examined and why.
-
Demonstrates fairness and thoroughness.
-
Supports HR processes, disciplinaries, and appeals.
-
Enables informed oversight by senior leaders and risk committees.
-
Withstands scrutiny from regulators, tribunals, and other external bodies.
​
This course helps investigators produce reports that stand up to scrutiny and support confident, defensible decision-making.
​
