Fredrick Herzberg was a psychologist whose theory includes the two-factor theory of job satisfaction. One factor is hygiene and the other factor is motivation. Hygiene factors are actually unsatisfactory work factors. An example of this is: a poor work environment or a poor relationship with the supervisor. Employees are happier when they work in a positive work environment, as Brunot (2013) says. Motivation factors include job satisfaction factors such as recognition and promotions. Herzberg believed that job dissatisfaction and job satisfaction are not completely opposite; in fact, his research has shown that they are distinctly different things. It is not because the factors of job dissatisfaction are eliminated that there is improvement and enrichment of the job. He taught that the best way to create improvement and enrichment at work is to create conditions conducive to job satisfaction, which will motivate employees. An example is to offer training for internal promotions. According to Ritzenhein (2000), Herzberg's teachings suggest that to motivate one must first get rid of the unsatisfying factors of the job and then look for ways to promote growth within the company.
