THE IMPACT OF SIDE HUSTLE AND ROLE CONFLICT ON BURNOUT: THE MODERATING ROLE OF WORK-LIFE BOUNDARY

Abstract

Side hustle activities have become part of modern work behavior as individuals seek additional income, flexibility, and career development outside their primary jobs. However, the
psychological impact of side hustle may depend on how individuals manage multiple roles and role boundaries. This study examines the effect of side hustle and role conflict on burnout, with work-life boundary as a moderating variable. A quantitative survey was conducted involving 78 working respondents with varying levels of side hustle involvement. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The measurement model met the criteria for reliability, convergent validity, and discriminant validity after several low-loading indicators were removed. The results show that role conflict has a positive and significant effect on burnout, while side hustle does not have a significant direct effect. Work-life boundary also does not significantly affect burnout and does not moderate the relationship between side hustle and burnout or between role conflict and burnout. The model explains 38.68% of the variance in burnout and demonstrates predictive relevance with a Q² value of 0.1698. These findings indicate that burnout in modern work arrangements is more strongly associated with role conflict than with side hustle itself. This study contributes to human resource management literature by highlighting role conflict as a key factor in explaining burnout among individuals who manage multiple work and personal responsibilities.
