Boardroom bigwigs are high-ranking executives in a company, usually the CEO and Chief Executives. CEOs, or Chief Executive Officers, are the highest-ranking executive in a company and are responsible for making major corporate decisions and managing the overall operations and resources of a company. Chief Executives are also high-ranking executives, but they are typically responsible for managing the day-to-day operations of a company. Both CEOs and Chief Executives are important figures in a company and are often referred to as boardroom bigwigs.
