Workplace Investigations

The employer must conduct the investigation, but the actual work can be done either by the employer's personnel or by an external investigator, for example, a law firm. Either way, there are no formal criteria for the persons executing the investigation; however, impartiality is required from the person conducting the investigation

There are no statutory or regulatory requirements regarding the choice of investigator in workplace investigations. However, it is good practice to have the investigation conducted by persons who have been trained to do so as investigations may involve intricate issues. It is also important that the investigators are perceived to be impartial and fair. For that reason, the investigators should be individuals who are not involved in the matter under investigation.

Complex cases or cases that involve a senior employee may require someone more senior within the company to lead and oversee the conduct of the investigation. This also applies where it is foreseeable that the investigation may lead to disciplinary action, summary dismissal of the employee or a report to an authority.

Engagement of external parties or professional advisors may be necessary if the conduct under investigation is serious or widespread and may lead to regulatory consequences, or if the employer does not have the requisite expertise to handle the investigation. Lawyers (whether in-house counsel or external lawyers) may be the best fit to conduct a workplace investigation to ensure that legal professional privilege attaches to documents and communications created during the investigation (please see question 14).

The process must be transparent and impartial, and therefore all the information that may influence the conclusions made during the investigation should be shared with the employee.

An employer’s internal policies or the employment contract may provide that an employee under investigation should be given certain information concerning the allegations raised against him or her. Such policies or terms should be followed and failure to do so may result in a claim for breach of contract or constructive dismissal by the employee. Even where there are no express provisions, the employer still owes an implied obligation of trust and confidence towards the employee at common law, which requires the employer not to, without reasonable and proper cause, conduct itself in a manner calculated and likely to destroy or seriously damage the relationship of confidence and trust between itself and the employee.[1] In the context of an internal investigation, the implied duty would require the employer to conduct the investigation and reach its findings reasonably and rationally following the evidence available and in good faith. This would normally require that sufficient information about the allegations made against the employee be provided to him or her such that he or she has the opportunity to properly respond to the allegations before any disciplinary action is taken or any decision about his or her employment is made.
