This study aims to analyze the influence of work stress and work discipline on employee performance in the Knitting Department of PT Kahatex, Cimahi, West Java. This research uses a quantitative method with an associative approach. Data collection techniques include pre-surveys, questionnaires, interviews, and document collection, with a population of 65 individuals (respondents) used as the sample. Data analysis includes validity tests, reliability tests, classical assumption tests, multiple linear regression analysis, correlation coefficient analysis, determination coefficient analysis, t-tests, and f-tests. The results show that work stress has a significant negative effect on employee performance by 34.2%. From the partial hypothesis testing, the value of t-count > t-table (4.876 > 2.000) was obtained, indicating that H0 is rejected and H1 is accepted, meaning there is a significant negative influence of work stress on employee performance in the Knitting Department of PT Kahatex. Work discipline has a significant positive effect on employee performance by 57.8%. From the partial hypothesis testing, the value of t-count > t-table (7.953 > 2.000) was obtained, indicating that H0 is rejected and H2 is accepted, meaning there is a significant positive influence of work discipline on employee performance. Based on the simultaneous hypothesis testing, work stress and work discipline together have a significant positive effect on employee performance, with a determination coefficient of 68.5%. The remaining 31.5% is influenced by other factors not examined in this study. The simultaneous hypothesis testing shows that the value of F-count > F-table (28.532 > 3.150), indicating that H0 is rejected and H3 is accepted, meaning there is a significant positive simultaneous influence of work stress and work discipline on employee performance in the Knitting Department of PT Kahatex, Cimahi, West Java.
