Participants preoccupied with themselves and the relationships within the group, excluding the training team is excluded to the detriment of the workshops

If the participants are more active in informal settings, for example during breaks, than during the workshop itself, this means that there is something wrong with how the training is set up. Review the methods you are using, the topics you open up, seek feedback from the group and try to collect open questions and comments from the participants. Ask them openly and devote time to this issue. Moving swiftly on and conducting another workshop in which participants are not fully active cannot take precedence over establishing a relationship of understanding and support between the team and the participants.
