Workplace Investigations

Privilege does not generally apply to internal investigation materials as the investigation does not constitute a relationship between a lawyer and their client, and even less so a judicial investigation. However, if a lawyer is appointed as an investigator, privilege may apply to materials exchanged between the lawyer and that client.

It would be difficult to assert privilege over materials that relate to the investigation itself.

Privilege may arise before the instigation of an investigation where an employer may seek legal advice from their legal advisors over the initial complaint and appropriate next steps. Subject to the relevant tests being met, Legal Advice Privilege arises in respect of a confidential communication that takes place between a professionally qualified lawyer and a client. Who the client is will be of significant importance as they must be capable of giving instructions to their lawyer, on behalf of the employer. Caution should be exercised by employers if advice to "the client" is disseminated further within the business to other members of management. If such a scenario arises, then there is a risk that privilege may be waived and such material could be disclosable under a data subject access request. Litigation privilege arises with respect to confidential communications that take place between a lawyer or a client and a third party for the dominant purpose of preparing for litigation, whether existing or reasonably contemplated.

It is also prudent to consider whether an external investigator should have access to their own independent legal advisor, and the funding arrangements for such advice would have to be considered by the employer.

The investigation will likely be able to continue with the other employees and, as soon as the employee under investigation returns from sick leave, they will be able to be interviewed.

However, as disciplinary sanctions are time-barred after two months from the moment the misconduct was committed or from when the employer becomes aware of it, if the sick leave lasts for the whole of that period, the investigation must be conducted anyway. In this instance, the investigator can ask the employee to attend the interview despite being on sick leave or arrange for the interview to take place using other means (eg, conference call). As a last resort, a questionnaire can be sent to the employee, but the pros and cons must be assessed as this is a way of information gathering that carries a certain amount of risk, could be less reliable and is of less probative value.

If an employee goes off sick during the investigation, it is reasonable to adjourn the investigation until the employee is fit to return to work. Difficulties arise if it is a prolonged absence. The absence may necessitate a referral to an occupational health expert and it may be necessary to seek medical advice as to whether the employee can continue to participate in the investigation. It may be that reasonable accommodations should be considered to ensure that the employee can continue to participate. Such situations may impinge on the investigator's ability to conclude the investigation. In that instance, it would be prudent for the investigator to document all attempts to involve the employee in the investigation and to assess whether it can be concluded without the further involvement of the employee.
