The presentation aims to impart the results of research carried out in a pilot study. The purpose of this study was to assess the awareness and use of expressions relating to business slang for the BGF PSZK students and professional economists. Based on the responses, I wanted to explore the frequency of business slang usage and the presumed causes of the differences between professionals’ and students' opinions. The respondents' language attitudes, language knowledge,
and subjective approach to the language were the focus of the study. In this way I could explore the relationship between the respondents’ usage of business slang terms and achieving actual success in the business world.
