Do Perceptions of Supervisors' Safety Responses Mediate the Relationship between Perceptions of the Organizational Safety Climate and Incident Rates in the Construction Supply Chain?

摘要

A multilevel safety climate survey was conducted m three Australian organizations in the construction supply chain. A principal components analysis (with varimax rotation) yielded six distinct safety climate factors reflecting aspects of the organizational safety response (OSR), supervisors' safety response (SSR), and coworkers' safety response (CSR). Perceptions of top management's commitment to safety (an aspect of OSR) and supervisors' safety expectations (an aspect of SSR) were both significantly and inversely correlated with the combined medical treatment and lost time injury rate of workgroups in the analysis. Further, regression analysis revealed that perceptions of supervisors' safety expectations fully mediated the relationship between perceptions of top management's commitment to safety and the workgroup injury frequency rate. The results highlight the critical role played by first-level supervisors in acting as the conduit through which organizational safety priorities are communicated to the workforce.
