Over the past 50 years, a number of papers have been published in an attempt to determine what factors make an employee happy and satisfied versus those factors that lead to dissatisfaction and poor performance. Perhaps the two most prominent authors are Frederick Hertzberg and Abraham Maslow. While Maslow first published his hierarchy of needs, Herzberg extended that work, developing his own needs model. The two models compare quite closely, with minor differences in the words used to define the separate levels of an individual's feeling of satisfaction on the job.
