Employee Investigations Under the PIA: What HR must get right before December 2026

One procedural misstep in an employee investigation can render your entire dismissal file unusable in court. Whether you are handling a dismissal for serious cause, investigating toxic management, or cooperating with internal compliance, the Belgian Private Investigation Act (PIA) governs how you do it — and the stakes for getting it wrong are rising fast.

With the mandatory deadline of 16 December 2026 to have an internal PIA policy in place, the time to act is now. PIA-related disputes are on a clear upward trend, particularly in dismissal cases. Having the right framework in place is no longer optional — it is a practical necessity for every HR and legal team.

Join us as we walk you through the key PIA obligations, share practical insights from the field, and highlight the pitfalls increasingly seen in recent cases. You will leave this seminar equipped to handle employee investigation files confidently within the PIA framework — and with practical tools to protect both HR and the wider organisation.
