Purpose: This study aimed to identify the effects of fatigue and emotional labor on the quality of sleep among apartment security guards. Methods: A total of 196 apartment security guards working in 10 different regions participated in the study between July and October 2022, completing questionnaire assessing fatigue (physical imbalance, exhaustion, mental fatigue, and nervous system disfunction), emotional labor, and sleep quality. Data were analyzed using descriptive statistics, independent t-test, Mann-Whitney U test, ANOVA including Scheffe’s post hoc, and regression analysis. Results: 183(93.4%) participants were poor sleeper. Regression analysis of the factors influencing sleep quality yielded a significant model (F= 21.56, <i>p</i><.001) with an explanatory power of 25.0% in the order of fatigue(exhaustion) (β=.28, <i>p</i><.001), emotional labor (β=.27, <i>p</i><.001), and subjective economic status (β=.15, <i>p</i>=.017). Conclusion: It is essential to develop nursing educational programs that reduce exhaustion and emotional labor for improving the quality of sleep.
