My assumption is that these students blame the others if things did not go as they had planned. For instance, the losing party in a vote would become aggressive towards the other and attempt to sabotage their projects. If you have never worked in a group where the people who do not get their way sabotage the group as a whole, I would consider you very lucky.

In the Sudbury School I work at, this does not happen. Occasionally there can be anger, but people get over it fairly quickly. It is not considered about winning or losing. It is a completely different frame of mind.

On the other hand, they are kids that are building their social models around those interactions, it might be very different from your usually company meeting.
