She also volunteered at De Leidse Rechtwinkel, where she provided free legal advice in the area of employment law to Leiden residents with limited financial means.

In the area of employment law, Sietske mainly works on HR-related matters such as dismissal (including summary dismissal), unacceptable behaviour in the workplace, reorganisations, and incapacity for work. Her approach is aimed at finding practical solutions that will help her client move forward, and this quality makes her an excellent sounding board for HR consultants.

Cross-border behavior in the workplace: how to create a safe organizational structure

4 March 2025

Approximately one-third of working Dutch people experience cross-border behavior in the workplace. Cross-border behavior, such as bullying, intimidation, or discrimination, deserves attention within organizations. A safe organizational structure is essential to prevent such behavior.

Often, unwanted behavior patterns, power imbalances, and unclear reporting structures creep into an organization unnoticed. These risks often lie within the organizational structure itself. By identifying these risks, you take an important step towards a safe and positive work environment. In this second blog of the series 'Cross-border behavior in the workplace,' I discuss six common risk factors. I also provide measures to reduce these risks and promote a safe work culture.

When external advisors have yet to receive their assignments. Because a works council that only wants to be involved at the advice request stage is often too late to make a real difference. Renate Vink-Dijkstra and I recently commented on a case in the JIN journal that illustrated this again.
