The Influence of Quality of Work Life, Organizational Commitment, and Intellectual Intelligence on Employee Performance at the East Medan Primary Tax Service Office

Organizational commitment reflects the level of employee loyalty and attachment to the organization, which encourages individuals to contribute optimally toward achieving organizational goals. The growing demand for transparent and accountable public services compels government institutions to optimize employee performance to deliver high-quality services to the public. This study aims to examine the influence of quality of work life, organizational commitment, and intellectual intelligence on employee performance at the East Medan Pratama Tax Service Office. A quantitative approach was employed using a survey method through the distribution of questionnaires to employees. The population consisted of 92 employees, with a sample of 90 respondents selected using a saturated sampling technique. Data were analyzed using validity and reliability tests, classical assumption tests, multiple linear regression analysis, t-tests, F-tests, and the coefficient of determination. The results indicate that organizational commitment and intellectual intelligence have a positive and significant partial effect on employee performance, whereas quality of work life does not show a significant partial effect. However, simultaneously, quality of work life, organizational commitment, and intellectual intelligence collectively have a positive and significant effect on employee performance. These findings suggest that enhancing organizational commitment and intellectual intelligence can contribute to improving employee performance within the organization.
