Abstract
Thailand is one of the major industrial
countries in Southeast Asia, with a workforce of approximately 38 million
people. In recent years, Thailand’s government has started to emphasize the
physical, mental, and spiritual well-being of the Thai workforce and has
encouraged businesses to apply the principles of the “Happy Workplace” to
enhance employees’ happiness and well-being. Although these principles can help
businesses to systematically improve employee well-being, there are still many
factors affecting employee well-being that are yet to be considered. This
research aims to study the context of supervisor leadership style and employee
well-being of Thailand’s M Chemical Company while conducting a departmental
comparison as part of the analysis. This research is a case study that utilized
literature analysis and interviews for data collection. The employees of the
four major departments from the production factory of M Chemical Company were
recruited as participants. The results showed that the difference in the
department's job characteristics and structure influenced the department
manager's leadership style. When the department manager is a transformational
leader, the principles of the Happy Workplace can be enhanced to further
improve the employees’ well-being.
Keywords: Leadership styles, Employee well-being, Happy workplace.
