Introduction to Motivation
At one time, employees were considered just another input into the production of goods and services. What perhaps changed this way of thinking about employees was research, referred to as the Hawthorne Studies, conducted by Elton Mayo from 1924 to 1932 (Dickson, 1973). This study found employees are not motivated solely by money and employee behavior is linked to their attitudes (Dickson, 1973). The Hawthorne Studies began the human relations approach to management, whereby the needs and motivation of employees become the primary focus of managers (Bedeian, 1993).
Motivation Theories
Understanding what motivated employees and how they were motivated was the focus of many researchers following the publication of the Hawthorne Study results (Terpstra, 1979). Five major approaches that have led to our understanding of motivation are Maslow's need-hierarchy theory, Herzberg's two- factor theory, Vroom's expectancy theory, Adams' equity theory, and Skinner's reinforcement theory.
According to Maslow, employees have five levels of needs (Maslow, 1943): physiological, safety, social, ego, and self- actualizing. Maslow argued that lower level needs had to be satisfied before the next higher level need would motivate employees. Herzberg's work categorized motivation into two factors: motivators and hygienes (Herzberg, Mausner, & Snyderman, 1959). Motivator or intrinsic factors, such as achievement and recognition, produce job satisfaction. Hygiene or extrinsic factors, such as pay and job security, produce job dissatisfaction.
Vroom's theory is based on the belief that employee effort will lead to performance and performance will lead to rewards (Vroom, 1964). Rewards may be either positive or negative. The more positive the reward the more likely the employee will be highly motivated. Conversely, the more negative the reward the less
