Purpose: This study aimed to analyze the effect of workload on employee performance at PT. Suryabumi Agrolanggeng.

Methodology: This study employed a quantitative associative approach. The population consisted of 150 employees of PT. Suryabumi Agrolanggeng, with a sample of 60 respondents determined using the Slovin formula with a 10% margin of error. Probability sampling with cluster sampling was used. Data were collected through questionnaires and analyzed using validity and reliability tests, simple linear regression, t-test, and coefficient of determination (R²) using SPSS version 26.

Results: The findings revealed that workload significantly affected employee performance. The t-test showed that the calculated t-value (7.237) exceeded the t-table value (1.6715), with a significance value of 0.000 (<0.10), indicating that the proposed hypothesis was accepted. The Adjusted R Square value of 0.728 indicates that workload explains 72.8% of the variation in employee performance, while 27.2% is influenced by other factors not examined in this study.

Conclusions: Workload is a significant determinant of employee performance at PT. Suryabumi Agrolanggeng. Effective workload management through proportional task allocation, realistic targets, and appropriate time allocation is essential for maintaining and improving employee performance.

Limitations: This study was limited to a single organization and focused solely on workload as an independent variable.

Contributions: This study contributes empirical evidence on workload management within the palm oil plantation industry and provides practical implications for human resource policies.
