Workplace Investigations

If there is no special statutory storage period (which is the case for investigative reports and findings), personal data may only be stored for as long as is necessary for the purposes for which they are collected. As soon as the data is no longer required, it must be deleted. In connection with workplace investigations, the question arises as to how this obligation to delete personal data relates to the company's corporate interests. From the company's perspective, there may well be legitimate interests that speak in favour of retaining existing data for as long as possible. Under the data protection regulations of the DSGVO and the BDSG, data can be stored for as long as it is required for the assertion, exercise or defence of (civil) legal claims. This means that the data can, in any event, be saved at least as long as any measures related to the workplace investigation have not yet been completed and any legal disputes have not yet been concluded.

The outcomes are usually kept in the records until termination of the employment agreement and only deleted when personal records are deleted.

Neither Polish law nor the Draft Law specifically provide for a mandatory period during which the outcome of the investigation should be kept on the employee’s record.

At the same time, the Draft Law indicates that the register of whistleblowing reports, which should also contain information about follow-up actions undertaken as a result of the report, should be kept for 15 months starting from the end of the calendar year in which the follow-up actions have been completed, or the proceedings initiated by those actions have been terminated.

Also, while determining how long the outcome of an internal investigation should be kept, additional legal considerations can be taken into account, especially data privacy.

The GDPR does not specify precise storage time for personal data. The employer must assess what will be an appropriate time for storage of the data, taking into consideration the necessity of keeping personal data concerning the purpose of the processing in question. Employees' personal data should be kept for the period necessary for the performance of the employment relationship and may be kept for a period appropriate for the statute of limitations for claims and criminal deeds. A longer retention period may result from applicable laws. Following the Regulation of the Minister of Family, Labour and Social Policy on employee documentation, the employer may keep a copy of the notice of punishment and other documents related to the employee’s incurring of disciplinary responsibility in the employee record.

There are different retention periods for the data contained in employee files:

• 10 years if the employee was hired on or after 1 January 2019;
•  if the employment relationship began between 1 January 1999 and 1 January 2019, the retention period is 50 years, but may be reduced to 10 years if the employer provides the Polish Social Insurance Institution with certain mandatory information; and
•  for 50 years if the employee was hired before 1 January 1999. It does not matter whether the person is still working or not.

From an employment law point of view, there is no statute of limitations on the employee's violations. Based on the specific circumstances (eg, damage incurred, type of violation, basis of trust or the position of the employee), a decision must be made as to the extent to which the outcome should remain on the record.

From a data protection point of view, only data that is in the interest of the employee (eg, to issue a reference letter) may be retained during the employment relationship. In principle, stored data must be deleted after the termination of the employment relationship. Longer retention may be justified if rights are still to be safeguarded or obligations are to be fulfilled in the future (eg, data needed regarding foreseeable legal proceedings, data required to issue a reference letter or data in relation to a non-competition clause).[1]
