Lack of effective occupational safety and health (OSH) strategies is a reason that

workplace accidents in the mining and quarrying industry remain high, making the

industry one of the riskiest operations worldwide. The purpose of this multiple case study

was to explore successful strategies mining and quarrying leaders in Zimbabwe used to

improve OSH. The key research question addressed successful strategies leaders in the

mining and quarrying industry use to improve employee occupational safety and health in

Zimbabwe. Six successful business leaders from 3 mining and quarrying mines in

Zimbabwe demonstrated an exception to unsafe practices, particularly through their

exceptional OSH improvement records. The conceptual framework of the study was

Deming's plan-do-study-act cycle theory. Data were gathered through review of

company documents, and in-depth interviews with 6 mining and quarrying leaders in

Zimbabwe who had successfully improved OSH strategies in the workplace. Transcribed

interview data were classified, coded, and analyzed. Themes that emerged included

organizational culture, compliance with rules and regulations, and accident prevention.

The results of the study indicate that successful OSH leaders designed the workplace,

trained and developed employees, and empowered and equipped employees with the

relevant skills and knowledge. The findings support positive social change by providing

mining and quarrying leaders with knowledge and skills to improve OSH strategies in the

workplace, thereby promoting a safe workplace and zero accident tolerance in the

workforce and the community.
