A manufacturing-oriented model for evaluating the satisfaction of workers – Evidence from Turkey

• We proposed an extensive model of job satisfaction comprising four principal factors that includes ergonomics and safety.
• We investigated the effects of job satisfaction elements in automotive industry using exploratory factor analysis.
• We introduced formulas for evaluating workers' actual satisfaction scores using multilinear regression analysis.

Job satisfaction, in terms of worker's satisfaction, is one of the intensively studied areas in human resource and management. However, there is little information available on how ergonomics and the manufacturing environment affect job satisfaction. This study analyzes the extent of the relationship between job satisfaction and work and workplace related conditions. A conceptual model is proposed to evaluate job satisfaction that considers 34 elements in four categories: manufacturing systems, facility design, safety and ergonomics, and human resources and management. A survey of 169 blue-collar workers working in the automotive industry was conducted to investigate the applicability of the model. A comprehensive exploratory factor analysis was used to determine inter-related elements, their underlying factors and their effects on job satisfaction. The analysis revealed 6 factors with 18 related elements. From a multi linear regression analysis, we develop a job satisfaction model built on factors of human resource policies, safety, ergonomics, air quality, thermal comfort and disturbing equipment. The results reveal that ergonomics plays the most important role in workers' satisfaction for the respondent Turkish automotive workers. In contrast, human resource policies seem not play a critical role in job satisfaction because of higher standards in automotive industry compared to other industries in Turkey.
