Workplace Investigations

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.

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

It may sometimes be difficult to draw a clear distinction between the property of the employer and employees’ personal property, both physical and electronic, particularly where employees are increasingly working from home. Employers should ideally have a clear policy to delineate what is the employer’s property.

Employees typically have a reasonable expectation of privacy at work, although how far this extends will depend on the circumstances of each case and the employer’s policies.

When it comes to employees’ personal possessions, a search should only be conducted in exceptional circumstances where there is a clear, legitimate justification. The employer should always consider whether it is possible to establish the relevant facts through the collection of other evidence. Even if the employee’s contract specifies that it is permitted, employers would usually require explicit employee consent for the search to be lawful. The employee should be invited to be present during the search; if this is not feasible, another independent third party (such as a manager) should be present.  

If the employee refuses to consent to a search of their personal possessions, their refusal should not be used to assume guilt; the investigator should explore why the employee has refused and seek to resolve their concerns if possible.

If the employer believes that a criminal offence has been committed it should consider involving the police, since they have wider powers to search individuals and their possessions.
