Starting from the recent quest to investigate the human side of organizational sustainability, this study applies a variety of regression analyses to investigate the effects of Lean Operations, High Involvement Work Practices, and management behaviors on occupational safety. It tests and finds support for the hypotheses that Lean Production systems, High Involvement Work Practices, and two specific management behaviors—workers’ capability development and empowerment —positively affect occupational safety. Furthermore, empowering behaviors positively moderate the effect of Lean Operations on workers’ safety. The (...) study bridges sustainable operations literature with theories related to the ethical side of safety management, sustainable HRM, ethical leadership, and empowerment. In doing so, it contributes to the understanding of occupational safety as constitutive aspect of organizational sustainability. (shrink)
