Workplace Investigations

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

The trigger could come from several sources, such as a grievance from a current or former employee, a complaint from external sources, a whistleblowing disclosure, or as the result of internal governance measures.

In each case, the employer will need to decide if an investigation is warranted. It may be required by internal policies or regulatory requirements in some circumstances. Consideration must be given to whether an investigation is feasible; for example, is the evidence still in existence and accessible? Are key witnesses still employed or contactable?

If the employer concludes that an investigation is warranted, it should start without unreasonable delay. The first step would usually be to set terms of reference, which outline the purpose and remit of the investigation. These should be closely drafted and continually referred to, to avoid the investigation’s scope expanding when new points arise (as they almost always will). An investigator will also need to be appointed (see question 4).

The examinations can be carried out internally by designated internal employees, by external specialists, or by a combination thereof. The addition of external advisors is particularly recommended if the allegations are against an employee of a high hierarchical level[1], if the allegations concerned are quite substantive and, in any case, where an increased degree of independence is sought.

The investigator would typically be a line manager or HR representative. Complex cases, particularly if criminality is suspected, or cases where a senior employee is accused of misconduct, may require the investigator to be someone more senior within the organisation, or someone from the in-house legal team. Employers should bear in mind the need for someone more senior than the investigator to act as a disciplinary decisionmaker, if disciplinary action is found to be warranted.

Check the organisation’s policies and procedures, which may stipulate who can act as an investigator.

The investigator should be someone without any personal involvement in the matters under investigation, or any conflict of interest, but with sufficient knowledge of the organisation and where possible with both training and experience in conducting investigations.

The business should consider how any prospective investigator may appear if they are called as a witness in court, or to give evidence before any governmental committee or regulatory panel. They should also consider whether the employee accused of wrongdoing should have any say in the choice of investigator; this would not typically occur, but having the employee’s buy-in can increase the chances of a successful outcome to the investigation.

It is becoming increasingly common for businesses to use an external consultant or lawyer to conduct workplace investigations. This may be beneficial where it is not operationally viable within the employer organisation to have a different person conducting the investigation and the disciplinary hearing, or if the investigation is particularly sensitive or complex, or relates to a very senior employee. If an external investigator is appointed, the employer remains responsible for that investigation.
