Relationship between abusive supervision and workers' well-being in construction projects: Effects of guanxi closeness and trust in managers

Purpose: The high-pressure nature of the construction industry, along with the COVID-19 pandemic, triggered abusive supervision (i.e. workplace bullying and incivility behaviour) that has diminished workers' well-being. However, despite the growing prevalence in practice and increasing concern in academia, abusive supervision remains largely unexplored by construction management scholars. This study aims to fill the gap in the current literature by analysing the effects of abusive supervision on construction workers' well-being, the mediating role of guanxi closeness and the moderating role of trust in the manager. Design/methodology/approach: A questionnaire survey was completed by 258 Chinese construction workers. The data underwent mediation and moderation analyses using PROCESS macro 3.5 for SPSS. Findings: The results revealed that managers' abusive supervision reduced construction workers' well-being at work and in life. Guanxi closeness between manager and workers mediated the relationship between managers' abusive supervision and construction workers' well-being. Additionally, trust in managers moderated the mediating effect of guanxi closeness. This study further revealed that the emotional connection between construction managers and workers, such as expressive guanxi closeness and affective-based trust, is important in handling the impact of abusive supervision on the workers. Practical implications: The findings of this study provide support for recent calls to address negative manager behaviours such as abusive supervision in construction management. They aid the development of a more comprehensive internal mechanism that considers the influence of guanxi closeness on the outcomes of abusive supervision by managers at construction sites. Additionally, interventions that develop trust in managers may be particularly effective in alleviating the tension of abusive supervision. More attention should be paid to managers' emotional connections in daily construction project management. Originality/value: Rather than concentrate on positive leadership, this study shifts the focus to negative leadership in construction project management by identifying abusive supervision as a negative primary antecedent of workers' well-being. While prior research has highlighted how negative manager behaviours affect workers' well-being from the conservation of resources theory (COR) perspective, this study is the first, to the authors' knowledge, to adopt a social exchange theory perspective by introducing guanxi closeness as a mediator. It contributes to a greater understanding of how trust in the manager alleviates the negative effect of the person's abusive supervision on construction workers.
