WORK MOTIVATION AS A MEDIATOR OF DUAL ROLES, JOB STRESS, WORK DISCIPLINE, AND WORK COMMITMENT ON FEMALE EMPLOYEE PERFORMANCE EVIDENCE FROM PT. HADJI KALLA, MAKASSAR

Abstract

  This study examines the direct and indirect effects of dual roles, job stress, work discipline, and work commitment on the performance of female employees, with work motivation positioned as an intervening variable. The research used a quantitative explanatory design at PT. Hadji Kalla in Makassar. The accessible population comprised 752 female employees. A minimum sample of 261 was calculated using the Slovin formula at a 5% error level; after questionnaire screening, 163 valid responses were analyzed. Data were obtained primarily through questionnaires and supported by observation, interviews, and documentation. Structural Equation Modeling (SEM) with AMOS was used to test the measurement and structural models, while mediation was evaluated using the Sobel test. The results show that dual roles and work commitment have positive and significant effects on work motivation, whereas job stress and work discipline do not. Dual roles, job stress, and work motivation have positive and significant effects on female employee performance, while work discipline and work commitment have no significant direct effects. Work motivation does not mediate the effects of dual roles, job stress, or work discipline on performance, but significantly mediates the effect of work commitment. Work motivation is the strongest direct predictor of performance (β = 0.754), while work commitment is the strongest predictor of motivation (β = 0.357). These findings place motivation as the central mechanism through which organizational attachment is translated into productive performance.
