The main aim of this paper is to Meta-analyse the literature on the impact of employees’ working relations in creating, maintaining and retaining trust. It is, thereby, the central work of this paper to measure the impact of trust variables, namely social system elements (SSEs), factors of trustworthiness (FoTs) and third-party gossip (TPG) on employee trust at the Bahrain Olympic Committee (BOC). A meta-analysis was conducted, as it offers the ability to critically assess and statistically aggregate the findings of related investigations. From a theoretical perspective, social exchange theory (SET) was used as a mediator of the relationship between employee working relation (SEEs, FoTs and TPG) and trust. In this regard, meta-analysis focuses on the three SSEs namely; employee involvement (EI), organisational justice (OJ), and corporate social responsibility (CSR), and three FoTs (benevolence, integrity and ability). More than 100 studies from 1995 to 2021 were included in the meta-analysis, as two databases were used including Google Scholar and Scopus. The meta-analysis results revealed different perspectives that contributed to overall trust development in light of SSEs, FoTs and TPG relations. In addition, the results found that FoTs promotes interpersonal trust while SSEs encourage trust at the organisational level. As the FoTs reflects interpersonal trust, SSEs indicate the formation of trust at the organisational level, revealing the importance of policies and regulations in BOC. The results reached that, TPG can be considered as an undermining social factor of employee trust in BOC because its impact can create distrust that can adversely affect the productive behavior of employees. This paper is unique and distinctive as it brings all employee working relation variables (SSEs, FoTs, and TPG) together in a single study. The comprehensiveness of the coverage focusing on the impact of each of these variables and their interrelationships contributes more and clearer insights and knowledge in the study of employee trust and enriches the trust literature for researchers. Such findings enrich the trust literature that can prove beneficial to researchers and scholars in the field in terms of juxtaposing the type of trust.
