Abstract
Convenience store employees responded to a survey form in response to questions about their own personality traits
and stress environment, and the data they responded to were statistically verified for lack of bias, and based on the
verified data, the information about convenience store employees' personality traits and stress environment was analyzed
using the Short Big Five theory and Multiple comparison tests were used to analyze the data. Factors contributing to the
stress they were under were classified according to personality traits, and characteristics were extracted. Based on the
classification results, we focused on the smiling during customer service, a potentially stressful task, as a response to
prevent stress, and confirmed whether smiling during customer service affects personality traits and is a superficial or
deep performance in the theory of emotional labor required as a convenience store employee's ability.
