Theoretical Framework for Informal Groups of Construction Workers: A Grounded Theory Study

Abstract

The current construction industry, which has a high accident rate and declining labor productivity, urgently requires efficient and practical management policies. Research has shown that social norms within informal groups have considerable influence on construction workers, while studies on informal groups of construction workers (IGCWs) have been scarce. Current theories of informal groups have not been analyzed in combination with construction industry characteristics. The purpose of this paper is to develop a theoretical framework of IGCWs, including definitions, types, characteristics, causes, and functions. First, on the basis of existing theoretical research of informal groups, two semistructured interviews were designed to collect data from managers and workers. Then, a qualitative approach using grounded theory with NVivo software was employed to code the interview information, and 25 subcategories were obtained: 5 types, 10 characteristics, 4 causes, and 6 functions of IGCWs. Eventually, a conceptual model was established to explain the definition of IGCWs according to the interview data and subcategories identified. This study not only contributes to improving behavioral science theory, especially group behavior theory and human relations theory, but also contributes to constructing an informal group theory of the construction industry. In practical terms, the targeted identification of IGCWs is useful for managers in taking measures to more effectively manage construction workers.

Analysis of the Cause of Household Carbon Lock-In for Chinese Urban Households

“…Open coding is followed by axial coding, which is also known as associative login or axis login. The purpose of axial coding was to explore the relationship between the independent categories formed in the open coding stage, discover the commonalities and logical connections between the categories, and form a clearer and more precise main category [ 51 , 52 ]. In the axial coding phase, the relationships between the 11 categories obtained in the open coding phase were refined and classified.…”

“…The retrieved information is condensed into several categories to form a conceptual system. Line-by-line or sentence-by-sentence is the most efficient way to conduct open coding analysis [ 31 ]. This step requires identifying and describing overall constructs relevant to precursors, based on the data set of 135 incidents.…”
