Read the following context. Then answer the question in well written paragraph (about five hundred words) and use correct terminology

Sarah is one of four group members in her AV clip group for her Organizational Behavior class at Cornell University. She has noticed that lately, one of her group members has started consistently arriving 15-20 minutes late for meetings. She also notices that this same group member lacks involvement in group meeting discussions and has not contributed to blog posts. Sarah doesn't know how this situation should be handled. She says that she doesn't have the confidence to say something to her fellow group member because she is nervous that he will become angry with her, and she fears her limited English skills will cause her to say something offensive. Her fellow group members say they have noticed the problem, but they say that the benefit of securing this group member's participation is probably not worth the likelihood of drama resulting from any confrontation about it.
