Effect of Safety Climate on Employees' Organizational Commit-ment Mediated by Organizational Ethics in Gas Refining Companies

Safety climate includes employees' overall perceptions and feelings about policies, procedures, and the importance of safety in the workplace. This study aimed to investigate the effect of safety climate on employees' organizational commitment mediated by organizational ethics in a gas refining company.

This cross-sectional and descriptive-analytical study was conducted in 2020. The study sample consisted of 220 employees of Parsian Gas Refinery selected through the Morgan Table. The instruments included three standard Safety Climate questionnaires by Haywick et al. (2009), Modaye et al. (1979), and Lozier (1993). Data were analyzed using the PLS software. The combined reliability of the structures was above 0.78, and Cronbach's alpha was 0.79. Furthermore, the value of the convergence of variables was above 57%.

The results showed that most subjects had an average age of 41-50 years, over 15 years of work experience, and undergraduate degrees. Additionally, the path coefficient was 0.79 between the safety climate and the organizational commitment, 0.82 between the safety climate and the organizational ethics, and 0.88 between the organizational ethics and the organizational commitment. Therefore, significant positive relationships were found between the safety climate and the organizational commitment of employees, between the organizational commitment and the organizational ethics of employees, and between the safety climate and the organizational ethics of employees (P<0.05).

The findings indicated that the safety climate explains 79% of the organizational commitment and 82% of the organizational ethics. Organizational ethics also explains 88% of the organizational commitment.
