Workplace Investigations

Workplace investigations can cause major problems for employers if they’re not conducted properly or by the right person.

What types of workplace investigations are there?

Employers will usually need to conduct an investigation before starting on a formal process with an employee, in order to collect evidence. An employer might also want to commission an investigation into wider workplace or cultural issues in order to safeguard their reputation or improve their working practices. The most common types of workplace investigations involve:

  • Grievances and discrimination complaints;
  • Disciplinary processes;
  • “Lessons to be learned” after the exit of a valued employee, or after an Employment Tribunal process;
  • Whistleblowing allegations;
  • Board disputes;
  • Workplace culture, HR practices and organisational change.

Why is the investigation stage so important?

The investigation is often the first step in a wider process which may end in a legal dispute, and getting it right is essential to set the foundations for that process and avoid risk down the line. However, just as important these days is the reputational factor. An employer can no longer guarantee that an investigation report will be kept confidential – leaks, whistleblowing disclosures and subject access requests can all lead to its disclosure or publication. A shoddy or inadequate investigation report can lead to the employer suffering reputational damage with its staff, clients or regulator, or even being singled out in the media.

What difficulties can arise during a workplace investigation?

Some of the most common pitfalls employers face when attempting to conduct an internal investigation are:

  • Obstructive employees: Employees are often unwilling to be completely honest during an investigation against them or one of their colleagues. An employee being investigated will often attempt to delay or stop the process, and a reluctant witness may try to refuse to give evidence altogether. It’s essential for the investigator to keep control of the process and deal with these issues swiftly and reasonably.
  • Confidentiality: Confidentiality can be a minefield during the investigation process and can throw up difficult legal issues such as what happens when a witness wants to remain anonymous, who should be shown a copy of the investigation report, or what to do if a leak occurs during the investigation.
  • “Mission creep”: An investigator may discover, or be told, something during the course of their investigation which they want to add to the list of allegations against the employee being investigated. However, this needs to be done very carefully, and at the right time, in order to prevent the investigation from snowballing and to prevent the process being deemed unfair.
  • Inexperienced investigators: Getting the choice of investigator right is absolutely essential to the success of the investigation. This is not just to avoid accusations of bias but also to ensure that the investigator is experienced enough to conduct and keep control of the investigation and prepare a watertight investigation report.
