Frederick Herzberg (1968) developed the theory by conducting a study with engineers and accountants’ examination of events in their lives. 1685 employees participated in the study with 16 investigations. The results of the study implied that;

• The factors causing satisfaction differ from the factors leading to dissatisfaction.
• The opposite of satisfaction is no satisfaction (instead of dissatisfaction) and the opposite of dissatisfaction is no dissatisfaction (instead of satisfaction). Thus, removing dissatisfying characteristics from a job does not make the job satisfying (Herzberg, 1968).
• There are two different group of individual needs; biological needs (avoiding pain) and growth. The former is satisfied externally (money, insurance, working conditions etc.) called as hygiene factors and the later intrinsically (achievement, recognition, responsibility, the work itself etc.) called as motivators.
• Factors causing dissatisfaction are the hygiene factors and leading to satisfaction are the motivators.
• When an employee is offered hygiene factors, the person is shifted to no dissatisfaction point after that the same person is provided motivators he/she moves to satisfaction level.
