The main problem in this study lies in the imbalance of workload, especially in the distribution of tasks in the work environment. This imbalance causes some employees to experience fatigue due to excessive workload, while others lack responsibility. In addition, problems also arise in aspects of the work environment, especially related to the instability of working time caused by the limited number of workers. This condition hinders work flexibility and reduces opportunities for interaction between teams, which in turn has the potential to reduce overall organizational effectiveness. This study aims to analyze the effect of workload and work environment on employee performance at the Regional Inspectorate of East Kalimantan Province. The research method used is a quantitative approach with multiple linear regression analysis techniques, using the help of SPSS software version 29. This analysis is complemented by validity, reliability, and classical assumption tests, which include normality, multicollinearity, and heteroscedasticity tests. To measure the influence on variables, a partial test (t test), simultaneous test (F test), and calculation of the coefficient of determination (R²) are used. The results of the study stated that: (1) Workload has a positive and significant effect on employee performance. (2) The work environment has a positive and significant effect on employee performance. (3) Workload and environment together have a positive and significant effect on employee performance at the Regional Inspectorate of East Kalimantan Province.
