WHAT YOU'LL LEARN
Following a realistic case study over three days, you’ll develop the knowledge, skills and understanding needed to navigate the full investigation process, from receiving concerns through to reporting conclusions.

Learning outcomes include (hover to expand):
Understand the core legal requirements governing workplace investigations, including UK employment law, human rights, data protection, and whistleblowing regulations.
Navigating the legal framework
Learn how to assess and triage concerns, grievances, reports of misconduct or whistleblowing disclosures, while handling sensitive information securely.
Receiving and assessing reports
Develop practical techniques for conducting whistleblower-driven investigations that safeguard reporters, ensure fair evidence collection and maintain robust, defensible processes.
Managing whistleblowers and whstleblower-led investigations
Identify and engage key parties and decision-makers; applying appropriate confidentiality and integrity safeguards whilst balancing conflicting priorities and expectations.
Stakeholder engagement
Develop a thorough understanding of how to identify, anticipate, and mitigate the risks that may impact an investigation, including legal liabilities, reputational damage, financial exposure, physical security vulnerabilities, and integrity-related concerns.
Risk management
Learn and understand key principles and practical steps to safeguard the integrity of an investigation. Ensure evidence, decision-making and records are handled securely and transparently, supporting a demonstrably professional process that stands up to scrutiny.
Professional and transparent case management
Conduct effective, structured interviews using the PEACE model, active listening techniques, and strategies for managing disruptive behaviour. Understand key legal and practical considerations, including accompaniment and reasonable adjustment rights.
Conducting structured, effective and ethical interviews

Analysing evidence and drawing defensible conclusions
Understand the principles of effective case reporting, producing clear, concise and defensible reports tailored to the intended audience. Learn how to structure and present findings accurately, and how to factor in context, culture and control gaps to develop practical, actionable recommendations.
Writing clear, impactful investigation reports
Understand legal concepts relevant to employment tribunals, emerging challenges and common pitfalls. Learn to navigate complex situations professionally, drawing on legal precedent and stated cases. Explore the role of employment lawyers and the appropriate use of legal privilege within the investigation process.
Handling legal risk and privilege effectively
Why this matters?
Workplace investigations are challenging, and the risks of getting things wrong can be substantial — leading to damaged reputations, legal complications, or unresolved issues that affect organisational culture.
Many professionals face uncertainty when tasked with managing investigations, often lacking confidence in their ability to gather and assess evidence or draw conclusions that will hold up under scrutiny.
The complexity of handling sensitive information, conducting interviews, adopting a trauma informed approach and navigating the nuances of each case can leave even experienced individuals feeling out of their depth.
By attending this masterclass, you'll gain the skills and confidence needed to overcome these challenges, ensuring that your investigations are conducted thoroughly and professionally. With the right tools in hand you will be equipped to safeguard your organisations integrity and contribute to a fair and transparent work environment.
