Understanding the role of trade unions in improving construction productivity through the institutional framework

Purpose - Sluggish performance in construction productivity (CP) is a common occurrence worldwide. This phenomenon is also observed in Singapore. In this context, the role of trade unions (TUs) has also been mentioned but appears to be little understood. Hence, this study evaluates the role of TUs in contributing to CP. The key issue is to determine whether TUs have a role to play in contemporary society in improving CP. Design/methodology/approach - This study takes on multiple research methodologies; more specifically, the mixed-method of survey questionnaires and interviews is used. Firstly, a survey questionnaire was employed to obtain broad viewpoints on the general understanding of the target groups towards the CP issues in Singapore. The survey questionnaire also attempts to study the TUs in greater depth by examining their existing strategies of and hindrances to improving CP. Once findings were gathered from the survey questionnaire, the interviews were carried out to probe deeper into the phenomena in the results. Findings - The research findings showed there is a generally positive outlook that TUs have the ability to contribute to CP. The study finds that the TU respondents possess strong attributes within the normative pillar, but weak attributes in the regulative and cultural–cognitive pillars. Originality/value - This study uses the Institutional Theory as a general framework, which identifies a union's functions and activities in three pillars that underpin the institutional theory and defines its impact on construction productivity.
