Job satisfaction has been studied so far in an attempt to understand employees' behaviors and attitudes. This topic has been specifically researched in sales as it has been shown that job satisfaction of sales personnel influences a number of key attitudes related to business and employee behavior. Job satisfaction will give employees a sense of fulfillment, accomplishment and therefore enjoy their job. Such feelings can make people more productive, more creative, and therefore more profitable for the organization in which they work. In this way, organizations stay abreast of competition or even gain a competitive edge over others. The aim of this thesis is to investigate the satisfaction of sales staff with the reward system used by their employer. The theoretical part outlines the role of sales in the organization and its tasks. Emphasis is also placed on the material rewards and intangible motivation of employees as well as their application. Some factors of job satisfaction, both organizational and personal, are explained. A survey questionnaire was also designed to investigate the satisfaction of sales staff. The results of the survey show that there are differences in employee satisfaction depending on their age, level of education, position in the workplace, years of service and the size of the company in which they work. The paper also takes into account the dependence of the reward system on the satisfaction of sales staff, that is, the satisfaction of sellers is shown depending on the reward used by their organizations.
