Sue van de Giessen
It is my pleasure to introduce myself as one of the internal confidential counsellors for social and organisational integrity of TU Delft.

During that time, I have built a strong bond with our university and many wonderful people who work here. Currently, I am working as department head of Media Innovation and Creation.
What I find important as a confidential advisor is that everyone - from employees to managers - finds space to share what is on their mind. Sometimes you may come across issues you would like to spar over or reflect upon. Please feel free to contact me, also if you are in a managerial role. I am here to listen, think along and support you in difficult situations, be it issues such as discrimination, business misconduct, harassment or other forms of questionable behavior.

External confidential advisor social and organisational integrity
Carin van der Hor
My name is Carin van der Hor. I work as an independent, external confidential advisor, mainly for organisations with social objectives. I also work as an interim manager, trainer and coach. I have worked in development cooperation and emergency aid for a long time and have always had a special interest in protection issues, including the topic of social safety.
As an external confidential advisor at TU Delft, I am a point of contact for all (former) employees and (former) students who are (or have been) confronted with undesirable behaviour or who have noticed a potential integrity violation of another kind. Examples of undesirable behaviour include (sexual) harassment, discrimination, bullying and aggression. If you are confronted with such behaviour, I can offer support and think along with you. Filing a complaint can be an option, but other solutions can be considered as well. You can also approach me if you have identified a possible integrity violation in the organisational field – such as a conflict of interest, financial fraud or abuse of power. In that case, you can discuss with me how you might report this. Important to bear in mind: everything we discuss remains confidential. I have a duty of confidentiality.
Send an email to carin.vanderhor@bmwvoorelkaar.nl or call/app me at phone number: 06-40016234. Should you not get me on the line immediately, please leave a voicemail message. I will then call back as soon as possible.
