Abstract

This study aims to explore the mediating role of Turnover Intention in the relationship between Co-Worker Support and Job Insecurity on Social Loafing among employees in the advertising, marketing, and event organization industry in Ho Chi Minh City. Based on a survey of 245 employees from 15 companies, the findings reveal that (1) Coworker Support significantly reduces Turnover Intention; (2) Job Insecurity both cognitive and affective positively influences Turnover Intention and Social Loafing; and (3) Turnover Intention serves as a significant mediator in the relationships between these factors and Social Loafing. In a high-pressure, fast-paced, and creativity-driven industry that demands strong team collaboration, these results emphasize the importance of fostering a supportive and psychologically stable work environment. Practical recommendations include enhancing Coworker Support through mentoring programs, experience-sharing activities, and constructive feedback; minimizing Job Insecurity by clear communication, skills training, and regular feedback mechanisms; managing Turnover Intention through periodic employee satisfaction assessments and well-defined career development paths; and cultivating a culture of cohesion and responsibility. This study contributes to a deeper understanding of employee behavior in creative service sectors and provides practical implications for businesses seeking to retain a stable and effective workforce.
