Alumni Events

Hosted by Mr Njombo Lekula, Ms Nomathemba Mhlanga and Dr Jako Volschenk

Facilitated by the Alumni Association Gauteng Chapter

Globally, companies are battling with balancing profits and doing what is right by society. Yet, it is common that employees blame corporate culture and corporate peer pressure for acting in ways that would be considered unethical, immoral, or illegal.

At the same time, when companies genuinely strive to be good corporate citizens, they fail because of employees that battle with social cues in these organisations. Corporate environmental initiatives rely on employees that buy into such initiatives.

Our research shows that employees weigh personal, organisational and social costs and benefits against each other when thinking about participating in such initiatives.

Book now to join Mr Njombo Lekula, Ms Nomathemba Mhlanga and Dr Jako Volschenk as they explore the battle to increase sustainability practices within organisations, and how risk assessment and ESG can be leveraged innovatively towards blended finance solutions.
