Abstract

This study is part of an ongoing research project that aims to understand workers' job satisfaction in the construction industry. For that, a survey was applied among construction workers in Denmark. This paper aims to identify the impact of Lean Construction on job satisfaction. Data from 2176 responses were analysed using framework analysis, shorting the answers into three categories: Lean knowledge; Lean application; and Lean operation, even though they declared not knowing Lean. The study investigated the impact of the different levels of Lean familiarity on job satisfaction within five aspects: Project progress; Management-employee relationship; Employee work monitoring; Workload; and Workflow. Findings indicate that only 15% of respondents have some knowledge of Lean concepts, with only 8% confirming its application. The strongest correlation (R2=0.557) was found between the Lean practice of “organization attempt to keep workers informed” and the job satisfaction factor of “manager-worker relationship”. Allowing the workers to evolve and improve presented, also, a strong correlation with job satisfaction. The study highlights that Lean practices that lead or require Respect for People are the aspects that impact the most on job satisfaction. The results emphasize that implementing Lean principles effectively matters more than merely being familiar with them.
