Workplace Investigations

Employers will generally take steps to treat complaints sensitively and confidentially. However, because of the obligations employers have, confidentiality cannot be guaranteed as part of the investigation and the complainant, respondent and witnesses should be made aware of this.

Understandably, the complainant or witnesses may wish to remain anonymous. However, because the details of the allegations need to be put to the respondent so that they can provide an informed response or explanation, the source of the information will often need to be disclosed.  

Employers can take steps to “ringfence” the investigation by asking employees to sign a confidentiality agreement. This will protect the interests of the participants of the investigation and uphold the integrity of the investigation.

See question 11, there is no protection of anonymity as the process must be transparent to the parties involved.

The outcome of the investigation must be disclosed to the complainant and respondent. If there is a concurrent police or regulatory investigation, they may request a copy of the investigation report. Employers should generally cooperate with regulatory authorities, but should be careful about disclosing the investigation report as this may be privileged and privacy obligations must be considered. Employers should consider only disclosing the investigation findings and interview records if compelled to do so by regulators or police.

Interview reports, the investigation report and communications about the investigation should be kept in a separate file. The file should be marked confidential and access to the file should be restricted.

If proceedings are commenced, the investigation materials may be subject to disclosure unless legal professional privilege can be asserted, see above.

In general, investigation materials, including findings, that includes personal data should only be processed by the personnel of the organisation who are responsible for internal investigations. However, it may in some situations be required by applicable legislation that findings are disclosed to competent authorities for the performance of their duties, such as conducting investigations in connection with malpractice and violations of the law.
