The Impact of Work Environment and Motivation on Job Satisfaction among Airline Ground Staff in Thailand

Abstract

Background and Aims: In the aviation industry, the work environment and employee motivation are crucial in ensuring job satisfaction and operational efficiency. Airline ground staff, often exposed to high stress, complex customer interactions, and physically demanding tasks, receive limited attention in research. This study investigated the relationship between work environment, motivation, and job satisfaction among airline ground staff in Thailand. It sought to identify key factors influencing satisfaction and provide insights for improving organizational practices to enhance employee retention and performance. Looking into the Job Demands-Resources Model lens, this study examined how work demands and resources impact employee well-being alongside the Self-Determination Theory, highlighting the role of intrinsic needs in fostering motivation and job satisfaction.

Methodology: This correlational quantitative study used random sampling to survey 200 airline ground staff in Thailand. Validated questionnaires measured Work Environment (α = 0.822), Motivation (α = 0.803), and Job Satisfaction (α = 0.787), showing good reliability. Descriptive statistics addressed the first three research questions, while Pearson correlation and regression analyses examined the relationships and predictive power of the independent variables on job satisfaction. The work environment tool is grounded in the Job Demands-Resources Model, explaining how a supportive work environment provides essential resources that help employees manage job demands and improve engagement. Motivation is explored through Self-Determination Theory, emphasizing that fulfilling intrinsic needs is crucial for sustaining high motivation and well-being. Job satisfaction is framed by Social Exchange Theory, which posits that when employees perceive fairness and organizational support, they reciprocate with positive attitudes such as increased satisfaction and commitment.

Results: The findings revealed that employees perceived a high level of the work environment (M = 4.11, "good environment"), motivation (M = 4.04, "highly motivated"), and a positive level of job satisfaction (M = 4.11, "highly satisfied"). The results indicate that employees experience favorable working conditions and strong motivational factors. Significant correlations were observed between all work environment dimensions, specifically the physical and non-physical aspects, and job satisfaction, with the strongest relationship (r = 0.603, p < .001), indicating that both tangible and intangible elements of the work environment play an essential role in employee satisfaction. Likewise, all dimensions of motivation were significantly correlated with job satisfaction, with non-monetary motivation showing the strongest association (r = 0.700, p < .001), underscoring the critical role of intrinsic motivators in enhancing job satisfaction. The regression results revealed that the work environment model had an R² value of 0.405, indicating that 40.5% of the variance in job satisfaction can be explained by factors related to the work environment. The motivation model yielded a higher R² value of 0.519, suggesting that motivational factors account for 51.9% of the variance in job satisfaction. These findings imply that while both predictors significantly influence job satisfaction, motivation explains more of the variation, highlighting its stronger predictive power in the model. The stronger influence of intrinsic motivation on job satisfaction among airline ground staff can be explained by Herzberg’s Two-Factor Theory, suggesting that true satisfaction arises from internal motivators like achievement and recognition rather than environmental conditions. Additionally, this is further supported by the Self-Determination Theory, which emphasizes that intrinsic needs such as employee autonomy, competence, and relatedness are key drivers of motivation, leading to higher job satisfaction.

Conclusion: The result demonstrates the essential role of work environment and motivation in job satisfaction. However, intrinsic motivators exhibit a stronger predictive power, accounting for a greater proportion of variance in job satisfaction. These results underscore the importance of fostering a supportive and engaging work environment while emphasizing intrinsic motivational strategies to enhance employee satisfaction and organizational well-being.
