Our Employment Policy aims to ensure that the demographic profile of each region we work in reflects the people that are employed by Kropz and our major subcontractors, promoting recruitment from communities as close as possible to the area where they work so that families stay together. We strive to attain gender balance and promote workforce stability and the retention of staff through exemplary working conditions as well as personal and skills development.

Kropz is a major investor into the South African economy and as a responsible corporate citizen it has embraced initiatives to promote Broad-Based Black Economic Empowerment (BBBEE).

Kropz strives to provide opportunities to all and promote responsible community projects to reduce income disparity. We believe that poverty can only be dealt with through local investment. In order to operate in a stable political environment, we have a moral obligation to create wealth and care for communities.

We regard BBBEE as essential for the development of South Africa and its economy and have achieved Level 4 status in terms of the Department of Trade and Industry’s BBBEE Codes of Good Practice.

Kropz supports the objectives and vision of The Broad Based Socio-Economic Charter for the South African Mining Industry (Mining Charter), published by the South African government in May 2015, which ensures that the Company achieves the following objectives;

  • Promotion of equitable access to the nation’s mineral resources to all people of South Africa.
  • Expansion of meaningful and substantive opportunities for all Historically Disadvantaged South Africans (HDSAs) to enter the mining industry and to benefit from the nation’s mineral resources.
  • Utilisation of the existing skills base for the empowerment of HDSAs.
  • Expansion of the skills base of HDSAs in order to serve the community.

The Company considers itself an Equal Opportunity Employer and thus aims to eliminate all forms of unfair discrimination in the recruitment and selection of staff.

To date, over 400,000 people have directly benefitted from the annual disbursement of funds through the Ubuntu-Botho Community Development Trust.

Ubuntu-Botho is Kropz’s Broad-Based Black Economic Empowerment partner in its Elandsfontein project. The shareholding structure of Ubuntu-Botho consists of the Motsepe Family Trust and a broad base of stakeholders that includes church groups, trade unions and women’s groups, amongst others, representing approximately 100,000 previously disadvantaged people, making it one of South Africa’s most broad-based empowerment groupings.
