The saying, ‘The high trees catch a lot of wind,’ means that people in important and high positions are constantly under the spotlight, subject to a continuous flow of comments and criticism.
Even so, does the saying apply to CEOs of companies, and even more to CEOs of top companies?
The CEO (chief executive officer) holds the highest-ranking position in a company and is ultimately responsible for the company’s success or failure.
There are numerous ways to describe the responsibilities of a CEO, including the functions in the following list:
- Oversee functions such as operations, finance, strategy, compliance, and business transformation, to name a few.
- Balancing the needs of employees, customers, shareholders, and other stakeholders.
- Take ultimate responsibility for the company’s performance, profitability, and sustainable growth.
- Provide leadership and guidance to senior management, other managers, and employees.
- Required to make swift decisions, communicate a clear vision, and foster a culture of innovation and excellence across the company.
Furthermore, being the CEO of a South African company is a demanding position with its fair share of stresses and numerous challenges.
CEOs of companies operating in South Africa are confronted with complex business environments, encountering political uncertainty, boycotts, labour unrest, cultural sensitivities, corruption, and high levels of inequality.
In addition, CEOs in South Africa often deal with difficult issues such as the ongoing issue of transformation and diversity in the workplace.
