The method used in this study is a quantitative research method using a descriptive approach . The data analysis used in this study was using SPSS 26 software. The analysis technique uses multiple regression analysis with the smallest square equation and the hypothesis test uses t-statistics and F test to test the regression coefficient partially and simultaneously, validity test, reliability, as well as classical assumption test which includes normality test, multicolonierity test, heteroskedasticity test and autocorrelation test. The results showed that there was a positive and significant influence of Work Shifts on Employee Performance. This is seen based on the results (t test) with a calculated t value > t table of 2,477 > 1,992 and a signification value of 0.016 < 0.05. Then there is a positive and significant influence of Work Fatigue on Employee Performance. This is seen based on the results (t test) with a calculated t value > t table which is 3,604 > 1,992 and a signification rate of 0.001 < 0.05.
