The effect of lean manufacturing practices on employees’ well-being mediated by job characteristics

Purpose Based on the principles of positive psychology, this study aims to investigate the mediating role of job characteristics (task, knowledge, social and work context) in the connection between lean manufacturing (LM) practices and employee well-being. Design/methodology/approach Employee well-being, encompassing job satisfaction, organizational affective commitment and work involvement, is conceptualized as a second-order construct. Using a proposed model, an online survey was administered to 520 participants across 23 operational sectors categories of the Brazilian manufacturing industry. The data is processed using structural equation analysis. Findings The research shows that the relationship between LM practices and employee well-being is partially mediated through three out of the four work characteristics (task, knowledge and social). In addition, LM exerts a direct and significant influence on employee well-being. Practical implications This study contributes to practical insights by encouraging industrial managers to refine their managerial work design. It highlights the importance of appropriately dimensioning tasks, nurturing social skills to enhance interactions and task execution and optimizing physical facilities to counteract potential initial-stage work intensification during LM implementation. Originality/value Previous research about organizational behavior extensively examines happiness at work, focusing on constructs such as well-being, satisfaction, commitment, engagement and motivation, but there is a lack of studies assessing employee well-being in the lean context, particularly from a positive perspective.
