Voice Endorsement and Employee Safety Voice Behavior in Construction Projects: The Mediating Role of Leader-Member Exchange

Scaling up a Positive Safety Culture among Construction Small and Medium-Sized Enterprises in Ghana

The Ghanaian construction industry faces challenges in managing safety, especially for small and medium-sized enterprises (SMEs) that need more resources. This research addressed the critical need for a positive safety culture framework specifically designed for SMEs in Ghana. The study adopts the Delphi research approach, which involves a series of questionnaire 'rounds' to gather and refine information and develop a collaborative safety culture framework with SME stakeholders. The study employed a mixed-methods strategy, harnessing quantitative and qualitative data to meet the research goals. The critical components of the developed framework included safety commitment, adaptability, information, awareness, culture, and performance. The research offered evidence-based recommendations for effective positive safety practices across Ghana's SMEs by analysing the relationship between these interventions and safety outcomes. Applying the framework should reduce workplace accidents and foster a positive safety culture that aligns with international best practices.

The mediating role of leader-member exchange (LMX) in the structural relationship between organizational justice and employee voice behaviour in higher education

Within the vibrant yet complex ecosystem of higher education institutions, nurturing a culture of employee voice is critical for driving innovation, fostering engagement, and optimizing decision-making. However, it's still a complex task to identify the main factors influencing voice behaviour. This study ventures into this fertile ground, examining the mediating role of leader-member exchanges in the structural relationship between perceived organizational justice and employee voice behaviour in higher education. A correlational study design was used. A total of 361 participants were involved in the study. Data were collected using a questionnaire and analyzed using structural education modelling (SEM). The study found that both perceived organizational justice and leader-member exchange have a significant direct influence on employee voice behaviour, suggesting that both variables are important factors in predicting employee voice behaviour. Despite these effects, the contribution of leader-member exchange was found to be more impactful than perceived organizational justice. When the leader-member exchange is entered as a mediating variable in the structural model, the indirect effect of organizational justice becomes large. This suggests that when employees perceive their organization as fair, they are more likely to form positive relationships with their leaders and, as a result, these relationships lead to greater employee voice behaviour. Therefore, it can be concluded that higher education institutions are recommended to create a fair and equitable working environment strengthened by strong relationships between leaders and employees, as this directly contributes to improving employees' ability to express their thoughts and opinions for the benefit of the institutions.

The Predictors of Unsafe Behaviors among Nuclear Power Plant Workers: An Investigation Integrating Personality, Cognitive and Attitudinal Factors

Unsafe behaviors, such as violations and human errors, have long been recognized as the main causes of accidents in nuclear power plants (NPPs). However, personal factors that influence unsafe behaviors among NPP workers have not been well examined, especially in an integrated model. This study proposes an integrated contextual mediated model to examine personality, cognitive and attitudinal predictors of unsafe behaviors among commissioning workers at NPPs. The model was verified using structural equation modeling technique with survey data from 177 commissioning workers in two Chinese NPPs. Results show that personality traits (i.e., conscientiousness, neuroticism, openness and agreeableness), executive function and safety attitudes exerted significant effects on unsafe behaviors. In addition, the effects of agreeableness and executive function were partly mediated by safety attitudes. Both conscientiousness and neuroticism indirectly influenced unsafe behaviors through the mediating role of executive function. The findings shed light on the design of evidence-based interventions for safety performance in NPPs.

How Safety Climate Impacts Safety Voice-Investigating the Mediating Role of Psychological Safety from a Social Cognitive Perspective

Safety voice has become a popular research topic in the organizational safety field because it helps to prevent accidents. A good safety climate and psychological safety can motivate employees to actively express their ideas about safety, but the specific mechanisms of safety climate and psychological safety, on safety voice, are not yet clear. Based on the "environment-subject cognition-behavior" triadic interaction model of social cognitive theory, this paper explores the relationship between safety climate and safety voice, and the mediating role of psychological safety. We collected questionnaires and conducted data analysis of the valid questionnaires using analytical methods such as hierarchical regression, stepwise regression, and the bootstrap sampling method. We found that safety climate significantly and positively influenced safety voice, and psychological safety played a mediating role between safety climate and safety voice, which strengthened the positive relationship between them. From the research results, it was clear that to stimulate employees to express safety voice behavior, organizations should strive to create a good safety climate and pay attention to building employees' psychological safety. The findings of this paper provide useful insights for the management of employee safety voice behavior in enterprises.
