Herzberg found five factors in particular that were strong determiners of job satisfaction: achievement, recognition, the work itself, responsibility and advancement. These satisfiers were associated with long-term positive effects in job performance, while the dissatisfiers consistently produced only short-term changes in job attitudes and performance, which quickly fell back to its previous level. In summary, satisfiers describe a person's relationship with what she or he does, many related to the tasks being performed. Dissatisfiers, on the other hand, deal with a person' relationship to the context or environment in which she or he performs the job. The satisfiers relate to what a person does, while the dissatisfiers relate to the situation in which the person does what he or she does. According to Herzberg´s theory, de-motivators must be reduced and motivators increased.
