Job satisfaction plays a critical role in the development of any organization because satisfied employees eventually develop a strong loyalty to their company and a commitment to increasing production, which ultimately results in the successful completion of projects within stipulated time, allocated budget. Various researchers have worked on this topic for different professionals, but construction industry labours are given less attention. The purpose of this research is to pinpoint the crucial success variables that have an impact on the workers’ job satisfaction in small-scale construction projects. The information was gathered from the labours using a questionnaire survey. Using the Statistical Package for the Social Sciences (SPSS), the Average Index (AI) approach was used to analyze the data gathered from 141 completed surveys. The factors salary on time, salary package or wages, relation with co-workers, facilities at site and workload were topmost critical factors which highly affect the job satisfaction. Whereas job security, leadership style, promotion opportunities and company policies were found to be moderately affecting factors. This study will enable the stakeholders of construction businesses and researchers as guidance to concentrate on the essential aspects that impact work satisfaction of the labour in building sector projects.
