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.

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.

There are no specific legislative requirements for workplace investigations in Vietnam. However, Labor Code No. 45/2019/QH14 dated 20 November 2019 (2019 Labor Code), which is currently the primary legislation governing employment relationships, requires employers that have more than ten employees to provide a mechanism and procedure for handling sexual harassment cases in the workplace. Other than that, an employer may incorporate policies and guidelines on how to deal with workplace investigations into its handbook.

While a labour union does not have a legal right under Korean law to be informed or involved in the investigation, unless otherwise required under the relevant collective bargaining agreement, there have been instances where the labour union raised complaints that the company did not properly investigate an employee, who is a member of the labour union, particularly if the company took disciplinary action against that employee based on the findings of the investigation. The company should consider such a practical risk when conducting a workplace investigation.

If the investigation was conducted based on a claim filed by an employee to the Grievance Handling Committee (which is a sub-committee of a works council), the members of that committee have a right to be informed of the results of the investigation.

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.

In Vietnam, the “trade union” is the only organisation solely dedicated to protecting employees’ legitimate rights and interests. Under the 2012 Labor Code, the term referring to trade unions was changed to “grassroots-level representative organisation of employees”. But the essence of this organisation remained and was later defined as “the executive committee of a grassroots trade union or the executive committee of the immediate upper-level trade union in a non-unionised company”. As such, it could be said that it was old wine in a new bottle.

As required under article 70.1 of Decree No. 145/2020/ND-CP, which serves as a guide to the Labor Code on working conditions and labour relations, when suspecting that an employee has committed a violation of labour discipline, the employer has to make a record of the violation at the time and notify the grassroots-level representative organisation of employees of which the employee is a member, or the legal representative of the employee if they are under 15 years of age. If the employer detects a violation after it has occurred, it will collect evidence to prove it. In this instance, the employer has no obligation to inform or involve the trade union or grassroots-level representative organisation of employees during the workplace investigation stage.

Also, an employee who is a member of the trade union or organisation has the right to seek assistance from this organisation and may authorise the trade union’s representative to represent and get involved in the workplace investigation.
