Job stress matters: Understanding how job stress moderates the relationship between person-environment fit and innovative work behavior in the Thai food industry

This study investigates the impact of person-environment fit and job stress on innovative work behavior within Thailand's food industry. Through a comprehensive survey conducted among supervisors in the food industry, validated scales were utilized to measure person-environment fit, job stress, and innovative work behavior while controlling demographic variables. Employing hierarchical regression analysis and moderation analysis, the study examines the direct and moderating effects of person-environment fit and job stress on innovative work behavior. Results reveal a significant positive relationship between person-environment fit and innovative work behavior, with job stress moderating this relationship. Notably, specific points of interaction between job stress levels and person-environment fit are identified, shedding light on nuanced dynamics within the food industry. This research introduces a novel approach by integrating the Job Demands-Resources Model with person-environment fit theory to explore how specific stressors unique to the food industry can influence innovation. The study also pioneers the use of industry-specific measures for assessing job stress and innovation, which were developed and validated within this context. This research contributes to both theoretical and practical knowledge by enhancing our understanding of innovation mechanisms in the food industry and providing actionable insights for fostering creativity and innovation among employees. The study's originality lies not only in its emphasis on the context of the food industry but also in its development of tailored theoretical and methodological approaches to address the sector's unique challenges and opportunities.
