The goal of any business is to motivate employees to perform work with the maximum results. The work motivation is complex and dynamic feature of human resources and influences to motivation are very broad and diverse. The material forms of motivation are different compensation that employees receive for their work in the company. They appear in the financial and non-financial forms （paid or in the form of various services）. The goal of this research is to identify the main factors of human resources motivation in financial institutions （banks）. The questionnaire will be used as a research instrument and consists of two parts. The first part of the questionnaire will focus on socio-demographic characteristics and the second part concentrates on the motivation variables of material and immaterial character. Applying adequate knowledge discovery research methods will be identified as the main motivation components of selling persons in financial institutions.展开更多
