Workplace Investigations

Interviewers, investigators, interviewees or any others involved in the investigation are often bound by a reinforced confidentiality obligation, particularly when the internal investigation is triggered by a whistleblower alert. In addition, every person that comes to know of the investigation, facts or people involved is bound by an obligation of discretion. Furthermore, investigators should specifically be trained for interviews and be reminded of their obligations relating to the investigation.

The investigators will need to determine the order of the tasks to be carried out in the investigation, as this will have a significant impact on confidentiality management. Should they start with the hearings or a review of documents? The answer may depend on the subject matter of the investigation. It is advisable to first review the documentation before organising interviews, particularly to avoid the destruction of certain documents by employees acting in bad faith or by those wishing to erase the traces of alleged wrongdoing. Sometimes, however, it is possible to start with the interviews, especially in the case of harassment, as there may be no documents to review. If the decision is taken to conduct the documentation review after the interviews, it could be useful to ask the employees involved to sign a document stating that they must preserve and retain documents, meaning that if they delete or destroy documents, they would be acting against the company and in breach of the law.

Unrelated matters revealed during the investigation do not necessarily mean that another investigation will be opened. Nevertheless, if reprehensible acts unrelated to the current investigation are revealed, the employer will need to take action and sanction the perpetrator (after checking the facts). Sometimes the only way to check the facts is to carry out another investigation on a separate matter. However, the investigation team may also consider if there is enough connection between the matters to widen the scope of the current internal investigation.
