Three basic rules

Introduction	On an individual level, trust is the certainty that things will happen according to my expectations and wishes. On a group level, it is a generally supportive, well-intentioned attitude toward each other. Rules help to facilitate a trusting working culture.
Discretion rule	“What we say here stays in the seminar room.” This confidentiatlity also includes pictures, stories, or videos, which are not allowed to be shared in social networks without explicit permission.
Stopping rule	"Whenever a participant feels uncomfortable with something that happened or is about to happen, they are allowed to say: STOP." In this event, they do not have to participate and do not need to explain why.
Disagreement rule	"Everybody has the right to agree and to disagree." Minority perspectives must be heard and respected, which also means that no one’s experience is marginalized or put in relative terms by the majority. The group does not have to agree – but everyone should at least try to increase empathy.
Discussion	Let the group discuss and find their own the seminar rules, reflecting their personal needs and goals. Therefore you might use another method like Code of Conduct.
