Workplace Investigations

A workplace investigation is often a sensitive matter that requires necessary confidentiality to find out the truth discreetly and objectively. Nevertheless, there is often pressure from employees, trade unions or even the media and general public to be transparent and communicate about the case. From a legal perspective, it is not recommended to communicate openly about an ongoing investigation, as this can jeopardise the investigation or the possibility of taking disciplinary measures.

Whistleblower investigations will be bound by a strict duty of confidentiality regarding anything that could reveal the identity of the reporter.

In complaints due to sexual harassment, violence or bullying at work, the prevention adviser is bound by professional secrecy. Consequently, he or she may not disclose to third parties any information about individuals that have come to his or her knowledge in the performance of his or her duties. However, he or she still has the freedom to inform the people concerned to carry out his or her tasks in the procedure.

Confidentiality applies as a general principle in disciplinary investigations.

Moreover, L. 4990/2022, which transposed EU Directive 2019/1937 into Greek Law, regulates the issue of confidentiality during investigations that start based on an internal report. The managers conducting the investigation must respect and abide by the rules of confidentiality regarding the information they have become aware of when exercising their duties[1]. They must also protect the complainant’s and any third party’s (referred to in the report) confidentiality by preventing unauthorised persons from accessing the report[2].

Finally, L. 4808/2021 provides that employers must create a procedure that should be communicated to employees regarding all the necessary steps of an investigation following a complaint. Throughout the whole process, the employer, managers and the employer’s representatives responsible for the investigation must respect and abide by the rules of confidentiality in a manner that safeguards the dignity and personal data of the complainant and the person under investigation[3].

Besides the employee's duty of performance (article 319, Swiss Code of Obligations), the employment relationship is defined by the employer's duty of care (article 328, Swiss Code of Obligations) and the employee's duty of loyalty (article 321a, Swiss Code of Obligations). Ancillary duties can be derived from the two duties, which are of importance for the confidentiality of an internal investigation.[1]

In principle, the employer must respect and protect the personality (including confidentiality and privacy) and integrity of the employee (article 328 paragraph 1, Swiss Code of Obligations) and take appropriate measures to protect the employee. Because of the danger of pre-judgment or damage to reputation as well as other adverse consequences, the employer must conduct an internal investigation discreetly and objectively. The limits of the duty of care are found in the legitimate self-interest of the employer.[2]

In return for the employer's duty of care, employees must comply with their duty of loyalty and safeguard the employer's legitimate interests. In connection with an internal investigation, employees must therefore keep the conduct of an investigation confidential. Additionally, employees must keep confidential and not disclose to any third party any facts that they have acquired in the course of the employment relationship, and which are neither obvious nor publicly accessible.[3]

It is recommended to limit the communication to the findings and details of the report that are necessary for the employee to fully understand the outcome. This is especially true if the investigation is bound by a duty of confidentiality (eg, under the whistleblowing rules), as the employee should not be allowed access to the full report.

There is no explicit legal provision stating the whole report must be communicated with the employee under investigation. The legal framework (L.4990/2022 and L.4808/2021) is governed by strict confidentiality obligations and obligations to protect the complainant’s data. From a data protection regulation perspective, it could be argued that the right of the person under investigation to know the identity of the complainant, witnesses or sources of information should be limited to protect the rights of such persons.

However, if the outcome of the investigation leads to the imposition of disciplinary measures, the right of the employee under investigation to request the whole investigation report, to aid in their defence is enhanced. Moreover, if a complaint is made in bad faith or is unfounded, it may be supported that the employee under investigation is entitled to receive full documentation so he or she can seek adequate legal protection or file an action before the courts.

In principle, there is no obligation to disclose the final investigation report. Disclosure obligations may arise based on data protection law vis-à-vis the persons concerned (eg, the accused). Likewise, there is no obligation to disclose other documents, such as the records of interviews. The employee should be fully informed of the final investigation report, if necessary, with certain redactions (see question 22). The right of the employee concerned to information is comprehensive (ie, all investigation files must be disclosed to him).[1] Regarding publication to other bodies outside of criminal proceedings, the employer is bound by its duty of care (article 328, Swiss Code of Obligations) and must protect the employee as far as is possible and reasonable.[2]
