The Impact of Supervisor–worker Relationship on Workers’ Safety Violations: A Modified Theory of Planned Behaviour

Abstract

This study develops and tests an integrative model to better understand the mechanisms by which the leadermember exchange (LMX) determines workers’ safety behaviours. The modified theory of planned behaviour (TPB) was proposed by using attitudinal ambivalence to replace univalent safety attitude. Empirical data were collected from 229 construction workers in China using a detailed questionnaire. Both situational and routine safety violations were considered in this model. The results showed that LMX had significant effects on both types of safety violations through three mediators from the modified TPB framework. Specifically, attitudinal ambivalence and group safety norm mediated the relationships between LMX and both types workers’ safety violations. However, perceived behavioural control only mediated the relationship between LMX and individuals’ routine safety violations. Furthermore, this research supported the distinctions between situational and routine safety violations. The indirect effects of LMX on individuals’ situational safety violations took place mainly through group safety norm. By contrast, the indirect effects on individuals’ routine safety violations took place mainly through attitudinal ambivalence and perceived behavioural control. Finally, the theoretical and practical implications, research limitations, and future directions were discussed. The results provide some meaningful insights into how to improve safety compliance behaviours from the perspective of supervisor-worker relationships.

Understanding the influence of safety climate and productivity pressure on non-helmet use behavior at construction sites: a case study

“…If safety inspection is frequently conducted such that workers feel more inclined to adhere to safety measures, they will take more initiative to promote safety awareness and act accordingly (Neal et al, 2000). Hence, safety inspections are regarded as a direct factor contributing to the improvement of safety climate at the construction site (Su et al, 2019).…”

Exploring construction workers' attitudinal ambivalence: a system dynamics approach

“…In the original TPB model, attitude was considered a predictor of behaviour, along with subjective norms and perceived behavioural control (Ajzen, 1991). In the modified models, several other factors were also identified as the latest causes of unsafe behaviour, such as workers' attitudes towards safety responsibilities and their risk perceptions, behavioural habits (Liu et al, 2020a), positive safety attitude (Hadjimanolis et al, 2015), as well as AA (Xu et al, 2018) (Su et al, 2019). The safety attitudes of supervisors and workers could also be a partial mediator in the relationship between safety knowledge and safety behaviour (Kao et al, 2019).…”

Informal Safety Communication of Construction Workers: Conceptualization and Scale Development and Validation

“…Parallel safety communication, an action between subjects with the same position, was more likely to promote safety behaviors compared with leader–worker interactions ( Zhou et al, 2008 ; Lingard et al, 2019 ). Given that the importance of leader–worker safety communication had been supported and highlighted in existing studies ( Huang et al, 2018 ; Su et al, 2019 ), parallel safety communication between workers needs more attention.…”
