Workplace Investigations

The employer must conduct the investigation, but the actual work can be done either by the employer's personnel or by an external investigator, for example, a law firm. Either way, there are no formal criteria for the persons executing the investigation; however, impartiality is required from the person conducting the investigation

As set out in question 1, workplace investigations must be proportional and companies must use the least intrusive means to affect employees’ rights. This translates into the following principles on who conducts the investigation:

• the enquiry must involve a minimal number of employees;
• only those employees with competencies on the investigated matters should be involved (normally human resources or compliance); and
• employees conducting the investigation must be qualified and have the power and seniority to do so proficiently (although a formal qualification is not required).

Please see question 7. The outcome of the investigation involving personal data may be retained only for as long as is necessary considering the purposes of the processing. In general, the retention of investigation-related data may be necessary while the investigation is still ongoing and even then the requirements of data minimization and accuracy should be considered. The data concerning the outcome of an investigation should be registered to the employee's record merely to the extent necessary in light of the employment relationship or potential disciplinary measures. In this respect, the applicable retention time depends on labour law-related rights and limitations, considering eg, the applicable periods for filing a suit.

The outcome of the investigation will contain personal data of the affected employee. For this reason, this information should only be kept for as long as a legal obligation or liability in connection with the information could arise for the company. Since the general statute of limitations for employment liability is one year, this is a good guideline.

In addition to the above, two specific rules apply:

• once the information becomes irrelevant for the purpose for which it was obtained and processed, the information should no longer be stored on the employee’s record or elsewhere; and
• the employees’ information (including those of the reporter and the affected employees) should only be stored in whistleblower systems during the time that is necessary to decide on whether the facts need to be investigated or not and, in any case, for a maximum period of three months.
