I. Introduction The case study focuses on an employee, Paul Keller, who is being affected by a number of factors. His job performance is hindered by constraints such as his work environment, his home environment, stressors, mood, and the management style of his superior. The case study demonstrates how his job performance is affected and what the consequences could be as a result of his poor job performance and lack of concentration.
II. Problems Paul is not able to perform his job well due to, in his opinion, being tired. The conversations with his wife that replays in his thoughts show how he is conflicted at home. He apparently does not have a strong, supportive home environment. The case study also shows that he does not receive much support from his superior at work either. He possesses many stressors that are affecting his personal and work life. Stressors are any demands, either physical or psychological in nature, that are created by external events encountered during the course of living (Greenberg, 2010). Stressors can lead to job strains. According to Greenberg in his text Managing Behavior in Organizations, strain is an alteration from normal states of human functioning that results from exposure to stress that can be psychological (e.g., depression), physical (e.g., headache, muscle aches), physiological changes (e.g., increased blood pressure), or behavioral (e.g., smoking or withdrawal from work). Paul is displaying a dimension of mood known as negative affectivity, which refers to the dispositional tendency to experience a variety of negative mood states. Individuals high in negative affectivity have been characterized as sensitive to minor frustrations and irritations and are more likely to experience negative emotions, such as anxiety, guilt, anger, rejection, sadness, and distress (Greenberg, 2010). This was not always the case with Paul.
