Workplace Investigations

While there are no specific laws that regulate a workplace investigation, there are several laws that companies should consider when conducting a workplace investigation concerning alleged employee misconduct.

One key example is the Whistleblower Protection Act (WPA). The WPA provides legal protection to a whistleblower if their allegations are raised in good faith and are in the public interest as specified under the WPA. If the WPA applies, certain obligations apply to the company, including but not limited to the following:

• the obligation to protect the confidentiality of the whistleblower’s identity;
• protecting the whistleblower if the whistleblower suffers or is likely to suffer serious harm to life or health as a result of whistleblowing and the whistleblower requests protection; and
• refraining from taking retaliatory action on the whistleblower.

Therefore, if an employee raises allegations of another employee’s misconduct, the company should review whether the allegations fall under the WPA.

There are also special laws that impose obligations on the company if there are certain types of allegations (eg, sexual harassment, workplace harassment).

In addition, when collecting and reviewing employees’ electronic data, such as emails or files stored in work laptops or company servers, which may contain personal information, the company should comply with data privacy laws discussed in more detail in questions 7 and 8.

Companies may also have internal policies (eg, whistleblower protection policies, Code of Conduct) that may apply to workplace investigations, aside from the requirements under Korean law.

Spain has not passed any statutes, regulations or policies specifically governing workplace investigations. Instead, general employment and data protection legislation, which safeguards employees’ rights, is fully applicable during these types of enquiries.

These statutes focus on employee privacy. As a result, the application of this legislation:

• limits the matters that may be investigated: they have to be relevant to the employment relationship and there has to be a legitimate reason to conduct the enquiry;
• sets boundaries to the means that may be lawfully used by the company in the investigation: they must be the least intrusive means for employees’ rights (for instance, an email review should be a last resort, reserved for when less-invasive means are not available or would not be effective); and
• states that the companies’ decisions during the investigation must be proportional in light of the facts under review and the legal consequences attached to them.

Collective bargaining agreements, which in Spain generally apply to every company within their scope of application (normally a given economic sector), may regulate workplace investigations. However, it is unusual for collective bargaining agreements to regulate workplace investigations.

Finally, major international corporations with a presence in Spain do tend to have an ethics or whistleblowing policy that governs how an investigation should be conducted. Even if these are self-imposed policies, they are contractually binding and, once established, must be respected by companies.

There is no specific legal regulation for internal investigations in Switzerland. The legal framework is derived from general rules such as the employer's duty of care, the employee's duty of loyalty and the employee's data protection rights. Depending on the context of the investigation, additional legal provisions may apply; for instance, additional provisions of the Swiss Federal Act on Data Protection or the Swiss Criminal Code.

Aside from the legal obligations imposed on the company when dealing with a whistleblower who is subject to the WPA as discussed in question 1, there are also practical considerations the company should keep in mind when dealing with a whistleblower, regardless of whether the whistleblower falls under the WPA.

For example, there have been instances where an employee who raised allegations filed a complaint with Korean authorities (such as the Anti-Corruption and Civil Rights Commission (ACRC) or the Labour Office) that the company took retaliatory action against the whistleblower. The company should carefully review the legal risks before taking action, such as personnel action or civil or criminal action, against an employee who raises allegations if that employee was also involved in the wrongdoing.

Directive (EU) 2019/1937 of the European Parliament and of the Council, of 23 October 2019, on the protection of persons who report breaches of Union law, has been implemented in Spain through Law 2/2023 (Ley 2/2023, de 20 de febrero, reguladora de la protección de las personas que informen sobre infracciones normativas y de lucha contra la corrupción). This law limits the capacity of companies to retaliate or to take any action against employees who report workplace violations or breaches of the law. Any action taken against an employee in such a position would be considered null and void if challenged in court.

Spanish law allows anonymous reports to protect whistleblowers from retaliation.

If an employee complains to his or her superiors about grievances or misconduct in the workplace and is subsequently dismissed, this may constitute an unlawful termination (article 336, Swiss Code of Obligations). However, the prerequisite for this is that the employee behaves in good faith, which is not the case if he or she is (partly) responsible for the grievance.
