The primary objective of the current study was to determine how job satisfaction effects the job performance of sugar industrial workers in Bangladesh. Moreover, this study examined the level of job satisfaction of employees in Bangladesh’s sugar industrial estate. In this quantitative study, respondents filled out a pre-structured questionnaire. The stratified random sampling approach was used to select 300 respondents from five sugar mills in the sugar industry. Job Performance Indicator (JPI), an 8-item self-rated performance scale, was used to assess job performance, and job satisfaction was measured using the JSI (Job Satisfaction Index). A regression analysis was performed using SPSS software for this study. Initially, reliability statistics were calculated for both scales in order to assess their relevance. The study’s findings showed a strong relationship between employee job satisfaction and job performance. The survey also showed that, compared to respondents’ personal characteristics, job-related factors had a greater impact on job performance. Furthermore, based on the findings of the study, job satisfaction among sugar sector workers in Bangladesh does not significantly differ by qualifications or age. In addition, the study found that foremen had a greater knowledge of the worksite than workers with less experience. However, the difference between the two groups was not statistically significant. There is strong evidence that employee satisfaction varies based on employee category. To improve job satisfaction and performance, the results and findings will be useful for the government, policymakers, and personnel departments of Bangladesh’s sugar mills. To make organizational decisions and policies about job satisfaction and job performance, it can be used to measure job satisfaction and the impact of job performance.
