Workplace Investigations

From an employment law perspective, confidentiality obligations may be seen from two different points of view:

• as a general duty of the employee related to the employment relationship, according to article 2105 of the Italian Civil Code, a “loyalty obligation”, which includes confidentiality obligations. On top of these, there are usually further confidentiality clauses in individual employment contracts; and
• as a general duty (linked to the outcome of the investigation) of the employer to keep confidential the identity of the employee who cooperates during the investigation (as whistleblower or a witness) to protect him or her.

In defensive criminal law investigations, the witness can’t reveal questions or answers given in his or her interview to a third party.

With regards to the confidentiality applicable to the whistleblower, see above under question 9 and below under question 12.

The law does not cover this issue, apart from whistleblower regulations, as it should be regulated by the employer in their internal rules. The employer should ensure all participants of the investigation keep information related to it secret, as long as is necessary for the investigation (or even longer, if required by law concerning personal data or other specially protected information). Reputation, personal data and the personal rights of other people cannot be breached during the proceedings and this should be protected.

Moreover, according to the Draft Law – a whistleblower’s personal data should be kept confidential. It can only be disclosed if law enforcement authorities require it. Also, confidentiality should be guaranteed for the subject and other interested persons.

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]

Generally speaking, a workplace investigation does not require the involvement of a trade union (on the assumption that no specific union agreement has been reached at a company level to entitle trade unions to specific forms of consultation or involvement in workplace investigations, which is not common).

According to section 4 of the Workers’ Statute, as stated above, the involvement of the trade union is necessary regarding the installation and use of specific equipment (such as cameras, switchboards, software) that potentially allows the employer to remotely monitor working activity, and which can be done only with prior agreement of the unions (or authorised by the labour inspectorate).  The union agreement must be made before the installation of the system, and therefore would normally be already in place when an investigation starts.

Pursuant to the WB Decree (Art. 4), union representatives (or external unions) should be “heard” before the employer activates a WB reporting channel[1].

There is no such obligation, unless it is provided for in an internal procedure or, for example, in the applicable collective bargaining agreement. It is neither a recognised practice nor recommended that such persons participate in the investigation.

However, in the event of violations that justify the termination of an employment contract with the employee, the employer should consult with that employee’s union about their intention to immediately terminate any employment contract concluded with that person or to terminate, with notice, the employment contract agreed with him or her for an indefinite term, or apply for consent to terminate the employment contract with an employee who is protected by a union.

In general, works councils and trade unions are not very common in Switzerland and there are no statutory rules that would provide a works council or trade union a right to be informed or involved in an ongoing internal investigation. However, respective obligations might be foreseen in an applicable collective bargaining agreement, internal regulations or similar.
