Workplace Investigations

Given that Spain lacks legislation in this area (see question 1), each company commences workplace investigations following its internal guidelines, policies or practices, if any. In our experience, investigations begin with a formal decision to commence the enquiry, which is set out in writing for record-keeping purposes.

This decision will normally mention:

• the facts that will be investigated;
• the reasons to investigate the facts (eg, they could be a breach of company policies);
• how the investigation will be conducted; and
• the individuals who will conduct the enquiry.

Depending on the company, the decision to initiate the investigation may take the form of a decision by the competent employee or officer (ethics or compliance officer) or the minutes of the relevant corporate body (board of directors or compliance committee).

Internal investigations are usually initiated after reports about possible violations of the employer's code of conduct, applicable laws or regulations have been submitted by employees to their superiors, the human resources department or designated internal reporting systems such as hotlines (including whistleblowing hotlines).

For an internal investigation to be initiated, there must be a reasonable suspicion (grounds).[1] If no such grounds exist, the employer must ask the informant for further or more specific information. If no grounds for reasonable suspicion exists, the case must be closed. If grounds for reasonable suspicion exist, the appropriate investigative steps can be initiated by a formal investigation request from the company management.[2]

The issue with revealing unrelated matters to the investigation is that it may jeopardise the entire enquiry. If the unrelated matters are private or the disclosure is construed as a breach of employees’ fundamental rights, then the materials gathered during the investigation could be considered to be unlawfully obtained and would not be admitted as evidence in court.

Moreover, the employee could seek damages and a fine could be imposed on the company for breaching its employee’s rights.

Finally, if unrelated matters are revealed, it could be a clear sign that the company has failed to conduct a diligent investigation and use the least intrusive means available to it (see question 1). One of the reasons to minimise the number of employees conducting the investigation (see question 4) is to reduce damages if matters unrelated to the investigation are revealed.

There are no regulations in this regard in the Swiss employment law framework. However, in criminal proceedings, the rules regarding accidental findings apply (eg, article 243, Swiss Criminal Procedure Code for searches and examinations or article 278, Swiss Criminal Procedure Code for surveillance of post and telecommunications). In principle, accidental findings are usable, with the caveat of general prohibitions on the use of evidence.
