One potential pitfall of group work are people with “problem personalities” in the group.  Linda D. Lerner wrote of these potential problem people in the Journal of Management Education.  The following are a list of such personalities:
· Nola No-Can-Meet
This person is always too busy to meet with the   group.  Usually says  to tell her what needs to be   done and she will do her part.
 
· Do-It-All Dottie
This person wants to make sure everything is done a certain way, so she tries to do it all herself.
 
· Seldom-Seen Steve
This person has not contacted anybody in the group.   He never comes to class and the other group   members are not sure if he is still in the
 class.
 
· Always-Right Artie
This person always thinks his ideas are the right way  for the group to go.  He does not listen to others.    He tries to do things his own way even when other  group members disagree.
 
· Quiet Quentin
This person may have some good ideas, but he never  speaks up.  He is always prepared and at all of the   meetings, but just sits quietly.
