Professional Orientation and Ethics

Please consider the folling case study and discuss personal reactions and possible courses of action.
-You are a counselor in a community clinic. A woman comes in to talk about a co-worker, who is acting more and more disorganized recently. She thinks her co-worker may be schizophrenic because he talks about noises he hears in his walls and recently has engaged in bizarre behavior. She is worried about her own safety, as he seems to be attached to her and she is the only one at work who he talks to about personal concerns. She wants to know what to do.
