Workplace Investigations

Under the GDPR (General Data Protection Regulation), personal data must be processed lawfully, fairly and in a transparent manner in relation to the data subject. The Data Protection Commission published Data Protection in the Workplace: Employer Guidance in April 2023, which is a useful guide.

Employers should exercise caution when gathering physical evidence that may involve the use of CCTV or other surveillance practices. The Irish Court of Appeal in the case of Doolin v DPC examined the use by an employer of CCTV footage for disciplinary purposes and found such use constituted unlawful further processing. The original reason for processing the CCTV footage was to establish who was responsible for terrorist-related graffiti that was carved into a table in the staff tearoom. It subsequently transpired Mr Doolin, who was in no way connected to the graffiti incident, had accessed the tearoom for unauthorised breaks and a workplace investigation followed. The original reason for viewing the CCTV related to security, but further use of the CCTV footage in the disciplinary investigation was not related to the original reason. This case confirms that employers must have clear policies in place in compliance with both GDPR and the Data Protection Act 2018 specifying the purpose for which CCTV or any other monitoring system is being used. Not only that, but these policies must be communicated to employees specifying the use of such practices.

It is not only data about the investigation that must be processed fairly, but any retention of the data, which can only be further processed with good reason. It is a legitimate business reason to retain data to deal with any subsequent requests or appeals under various internal or statutory processes, provided employees have been advised of the relevant retention period.

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.

The first consideration here is what constitutes "employees' possessions". More often than not, employees will be using employer property and there should be clear policies in place that specify company property.

The difficulty arises if an employee is using personal equipment such as a mobile phone for work purposes. While there may be specific applications dealing with work-related matters that are accessible by the employer remotely, some applications may be device-specific and that is where issues may arise. In such instances, it is not unreasonable to ask the employee to provide such information or consent to a search of their personal property. However, this is the exception rather than the rule and all other legitimate avenues of obtaining such information should be explored first. Further, such requests for information should not be a fishing expedition as an employee has a reasonable expectation of privacy at work, which must be balanced against the rights of the employer to run their business and protect the interests of their organisation.

A search of physical items such as a desk or drawers should only be conducted in exceptional circumstances, even where there is a clear, legitimate justification to search and the employee should be present at the search.

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]
