The purpose of this study is to categorize changes in the quality of youth employment during the outbreak of COVID-19 and to identify the factors affecting them. For this purpose, data from the Youth Panel Survey (YP) of the Korea Employment Information Service was used. In the case of the original sample, data from the 13th and 14th surveys conducted in years 19 and 20 were used. And for additional samples, the 5th and 6th data surveyed in the same period were used. The analysis method used latent profile analysis and multinomial logistic analysis. The conclusions drawn through the study are as follows. First, as a result of categorizing changes in the quality of employment based on changes in wage level, changes in working hours, and changes in job satisfaction among young people working as wage workers before and after COVID-19, they were significantly classified into four groups. Second, as a result of classification analysis, the ‘job satisfaction increase’ group improved the quality of employment, and the ‘wage decrease’ and ‘increase working hours’ groups showed that the employment quality deteriorated. Third, as a result of performing multinomial logistic analysis to identify the factors affecting each type of change in the quality of youth employment, it was found that individual job-related variables had a significant impact on the change in employment quality. Based on the results derived from this study, suggestions, and significance related to the quality and employment change of youth employment after the outbreak of COVID-19, and discussions for future research were proposed.
