NS has the following core values: we are open and reliable, we go for results and we want to get ahead. These values are the foundation of what we do and what passengers can expect from us. The NS Code of Conduct is in line with the OECD guidelines and serves as a guide for employees when weighing up options and making carefully considered choices in diverse and sometimes tricky situations. NS draws the attention of its staff to the Code of Conduct and working ethically in various ways, such as an e-learning tool and a game in which staff can discuss dilemmas in their work with one another or as a team. Furthermore, the NS Code of Conduct forms a basis for handling reports relating to integrity and investigations into integrity.
