THE INFLUENCE OF WORK LIFE BALANCE, SUPERVISOR SUPPORT, AND KNOWLEDGE SHARING ON JOB SATISFACTION AMONG MILLENNIAL EMPLOYEES AT PT INTI SUKSES GARMINDO

Abstract

This research examines how work-life balance, supervisor support, and knowledge sharing shape job satisfaction among millennial employees working in the export-oriented garment sector, taking PT Inti Sukses Garmindo as the research setting. The motivation for the study stems from a marked increase in millennial employee turnover at the company shortly after the Eid al-Fitr holiday period. A quantitative, cross-sectional design was applied, with primary data gathered through a questionnaire administered to 150 millennial employees chosen through purposive sampling and processed via multiple linear regression. Findings show that Work-Life Balance, Supervisor Support, and Knowledge Sharing each exert a positive and significant influence on Job Satisfaction, whether examined individually or together, with the regression model accounting for 74.6 percent of the total variance in Job Satisfaction. These results demonstrate that job satisfaction among millennial workers in labor-intensive manufacturing arises from an interplay between individual factors balancing professional and personal life and organizational factors supervisory support and a shared culture of knowledge exchange. Theoretically, the study extends Self-Determination Theory into the garment manufacturing context, and practically, it offers management guidance for designing policies that curb turnover by reinforcing these three dimensions.
