Workplace Investigations

The basic rule is that the employer may not search private data during internal investigations.

If there is a strong suspicion of criminal conduct on the part of the employee and a sufficiently strong justification exists, a search of private data may be justified.[1] The factual connection with the employment relationship is given, for example, in the case of a criminal act committed during working hours or using workplace infrastructure.[2]

There is no explicit answer to this question. However, it is important to make a distinction between employees’ possessions and files that are strictly personal and employees’ possessions and files that are found on devices or files provided for company use. For the first category, the employer does not have the right to search employees’ possessions and files. For the latter category though, justifications need to be established, by observing the requirements explained in question 7. Furthermore, the employers must also ensure that employees are fully and explicitly informed in advance of the monitoring operations, either through a provision included in the employment agreement, or in a separate notice or employee policy, the receipt of which should be duly acknowledged by the employee.

In addition to the above-mentioned statutory confidentiality obligations, separate non-disclosure agreements can be signed. In an internal investigation, the employee should be expressly instructed to maintain confidentiality.

It is crucial to keep the events and facts of a workplace investigation confidential for the integrity of the process. It may be necessary to consider appropriate confidentiality measures to protect the complainant, mitigate risks, and preserve evidence. Damage to the confidentiality of the case can prevent the investigation team from bringing the case to a correct and complete conclusion. Although the labour legislation imposes a general confidentiality obligation on employees, NDAs can still be used as supplementary documents that may emphasise the confidentiality obligations of employees in workplace investigations and provide additional contractual protections such as penalties if there is a breach.
