Given the recent findings which indicate that job satisfaction is largely genetically determined, why should managers care about employee job satisfaction?

Essay from the year 2012 in the subject Business economics - Personnel and Organisation, grade: 0.844, EBS European Business School gGmbH, language: English, abstract: Different fields of research showed that companies obtain improved results if their employees are satisfied with their job. Thus, job satisfaction is essential for employees' job performance. Satisfaction in return is influenced by different aspects: one of which is the individual's personality.
In the following, I will discuss the question to what extend genes determine job satisfaction, and for what reason and how managers should care about employee job satisfaction. I will refer to a study, which shows how genes influence job satisfaction. The results of the study lead to the assumption that personality influences satisfaction directly. To conclude I discuss the importance of job satisfaction for managers and how they should take care of it.
