Workplace Investigations

When collecting data (in physical or digital form), the employer must ensure compliance with the data protection principles according to the General Data Protection Regulation (DSGVO) and the German Data Protection Act (BDSG). These principles include, among other things, that data collection must be carried out lawfully (principle of legality) and transparently (transparency principle) and must be comprehensively documented – specifically concerning the purpose of the workplace investigation – to be able to prove compliance with data protection.

The principle of legality states that data may only be collected on a legal basis (ie, there must either be a law authorising this or the employee must have consented to the collection of his data).

The transparency principle may constitute a special challenge during workplace investigations. Under the transparency principle, the employee must be generally informed about the collection of his data. This includes information on who processes the data, the purposes for which it is processed and whether the data is made available to third parties. However, there may be a risk of collusion, particularly when electronic data has to be reviewed, and thus the success of the investigation may be jeopardised if the relevant employee is comprehensively informed in advance. Accordingly, the employer should check, with the assistance of the data protection officer, whether the obligation to provide information may be dispensed with. This may be the case if providing the information would impair the assertion, exercise or defence of legal claims and the interests of the employer in not providing the information outweigh the interests of the employee. The respective circumstances and employer's considerations should be well documented in each case.

Regardless of whether the employee is informed about the investigation, to prevent data loss, the employee should be sent a so-called hold notice (ie, a prohibition to delete data). Additionally, to prevent automatic deletion, blocking mechanisms should also be implemented.

When gathering evidence by searching the employee's possessions or files, the employee's privacy rights also need to be observed (see question 8).

Dutch data protection rules are based on the EU Data Protection Directive. The employer has to notify the Dutch Data Protection Authority when processing personal data as part of an internal investigation. Given that the notification can be accessed publicly, it is recommended that the employer give a sufficiently high-level description of the case. In addition, the description should be sufficiently broad to include the entire investigation, and any future expansions of the scope of the investigation. Often companies make filings for all future internal investigations, without referring to specific matters.

The employer has to notify employees whose personal data is being processed about – among other things – the purposes of the investigation and any other relevant information. According to the Dutch Data Protection Act, this information obligation may only be suspended on restricted grounds, i.e. if the purpose of the investigation is the prevention, detection and prosecution of crimes and postponement is necessary for the interests of the investigation (e.g., because there is a risk of losing evidence, or collusion by individuals coordinating responses before being interviewed)). These exceptions on the duty to inform involved persons must be interpreted very restrictively. As soon as the reason for postponement is no longer applicable (e.g., because the evidence has been secured), the individuals need to be informed.

Dutch data protection law does not require the consent of employees. Consent given by employees, however, also cannot compensate for a lack of legitimate purpose or unnecessary or disproportionate data processing, as the consent given by an employee to its employer is not considered to be voluntary given the inequality of power between them.

Furthermore, internal company policies may contain specific data protection rules.

The Swiss Federal Act on Data Protection applies to the gathering of evidence, in particular such collection must be lawful, transparent, reasonable and in good faith, and data security must be preserved.[1]

It can be derived from the duty to disclose and hand over benefits received and work produced (article 321b, Swiss Code of Obligations) as they belong to the employer.[2] The employer is, therefore, generally entitled to collect and process data connected with the end product of any work completely by an employee and associated with their business. However, it is prohibited by the Swiss Criminal Code to open a sealed document or consignment to gain knowledge of its contents without being authorised to do so (article 179 et seq, Swiss Criminal Code). Anyone who disseminates or makes use of information of which he or she has obtained knowledge by opening a sealed document or mailing not intended for him or her may become criminally liable (article 179 paragraph 1, Swiss Criminal Code).

It is advisable to state in internal regulations that the workplace might be searched as part of an internal investigation and in compliance with all applicable data protection rules if this is necessary as part of the investigation.

Workplace investigations that do not require the presence or active cooperation of the employee may also start or continue during the employee's absence due to illness. If the employee's cooperation is required, for example for an interview, the employer can only instruct the employee to participate despite an existing illness if certain narrow conditions are met:

Regarding staff meetings at the company, the German Federal Labour Court has ruled that the employer can only instruct the employee to attend the staff meeting during illness if

• there is an urgent operational reason for doing so, which does not allow the instruction to be postponed until after the end of the incapacity to work; and
• the employee's presence at the company is urgently required and can be expected of him.

Similar rules are likely to apply to the employee's presence for workplace investigations.

Urgent operational reasons that cannot be postponed could exist, for example, if during the employee's absence due to illness, there is a risk that evidence will be lost (eg, where only the employee affected has access to certain files or data) or there is a risk of significant damage to the employer if workplace investigations are stopped until after the employee's return.

If the employee under investigation goes off sick during the investigation, they will generally be treated as a regular employee on sick leave, meaning they are entitled to continued salary payment and that both employer and employee have a reintegration obligation. This entails regular consults with the company doctor to determine how recovery progresses and when the employee can return to work. If the employer suspects that the employee is merely calling in sick to delay the investigation and such suspicion is not confirmed by the company doctor, the employer can ask the Employees Insurance Agency (UWV) to give a second opinion. When it is determined that the employee is in fact fit for work, the employer can oblige the employee to return to work and cooperate with the investigation. If the employee fails to comply, the employer can – after due warning – suspend the employee's salary payment.

The time spent on the internal investigation by the employee should be counted as working time[1]. The general statutory and internal company principles on sick leave apply. Sick leave for which the respective employee is not responsible must generally be compensated (article 324a paragraph 1 and article 324b, Swiss Code of Obligations). During certain periods of sick leave (blocking period), the employer may not ordinarily terminate the employment contract; however, immediate termination for cause remains possible.

The duration of the blocking period depends on the employee's seniority, amounting to 30 days in the employee's first year of service, 90 days in the employee's second to ninth year of service and 180 days thereafter (article 336c paragraph 1 (lit. c), Swiss Code of Obligations).
