There are many reasons that can justify the importance of framing the activities of a group with explicit rules. The leader becomes aware of the emotions that are at stake. Either the members of a group do not know each other very well, or the group is made up of fragile leaders with an underlined emotional profile, or very personal comments must be expressed with a certain vulnerability. These are all good reasons to put your framework well within the group. Ensure that the rules that help us operate are clear and explicit. A conscious leader will know how to anticipate this need and give it all its importance from the start. Guaranteeing the emotional security of members of staff is a priority to create trust and facilitate exchanges. What do we need to make this work between us? It is not a question of imposing conditions but of agreeing on the type of collaboration desirable.
