The correct answer to this open question is the following.
Conflict typically appears when a group is in transition. The forms of conflict you can expect in the types of groups you will lead are misunderstandings, lies, lack of communication, lack of commitment, egotism, a sense of survival, different points of view, fear of change, uncertainty to the unknown, among other.
Often, group members are going to try to survive, trying to defend their positions and protect themselves first, instead of working for the benefits of the organization.
I would attend to these problem group members by showing solid leadership and behaving like a person that has the experience and the knowledge to confront complicated situations with no fear, instead of hiding or running away from problems.
As the leader, I am the first to show the example and my conduct has to be congruent with my words and actions so the members of the group can trust me.
