The purpose of this study was to reveal the effects of sales services and organizational member relationships of fashion brand salespersons on job performance and job satisfaction, as well as how job performance, job satisfaction, salesperson services, and organizational member relationships differ according to the sales career and job position. The data were collected by administering a questionnaire to fashion brand salespeople in Gwangju from September to October 2020. Using 235 responses, the data were analyzed with SPSS 27.0 for frequency analysis, reliability analysis, t-test, factor analysis, and regression analysis. The research results were as follows. First, the basic services of the salesperson comprised factors such as ‘consideration and convenience’, ‘appearance and dress’, and ‘kindness and greeting’, which are considered better variables to explain job performance than job satisfaction. Second, the salesperson’s professional service consisted of ‘fashion product knowledge’, ‘professional self-management’, and ‘store display technology’ factors, which are good variables to predict job performance. Third, the relationship between the members of a salesperson’s organization consists of factors such as ‘headquarters relations’, ‘colleague relations’, and ‘emotional labor’, which was better for explaining job satisfaction than job performance. Fourth, depending on the position, professional salespeople exhibited significantly higher values in job performance, basic and professional services of salespersons, and ‘headquarters relations’ factors, whereas there were no significant differences in job satisfaction, ‘colleague relations’ and ‘emotional labor’. Lastly, the more sales career, the higher the job performance, and the basic services, professional services, and ‘headquarters relations’ factors of salespeople were also good.
