Organizational injuries and accident has become a major issue in many countries especially among foreign workers in the construction sector. This paper aims to examine the safety behavior of foreign workers in the Jeddah construction industry by examining the direct relationships between safety management practices (priority of safety, safety communication, and work pressure) on safety compliance and safety participative behavior. Also, social support was tested as a moderator on these relationships. Partial Least Square Techniques 3.0 (PLS) approach was used to test the hypotheses. The finding showed that the priority of safety and safety communication predicts both safety compliance and participative behavior in this study. While the relationships between work pressure and safety compliance and participation are not significant. Results for the moderation effects of social support revealed that the relationship between safety communication and work pressure on safety participation was influenced by social support. The finding in this study provides empirical support of social support as a moderator and contributes to the role of social exchange theory and can assist construction practitioners in Saudi Arabia on how to improve construction workers safety behavior. Finally, this study discusses theoretical and practical implications, as well as recommendations for future research.
