Character is made up of core moral principles called the Six Pillars of Character: trustworthiness, respect, responsibility, caring, fairness and citizenship. Each of these virtues are independently important but together they provide the foundation for a worthy life.
Using the phrase business ethics might imply that the ethical rules and expectations are somehow different in business than in other contexts. There really is no such thing as business ethics. There is just ethics and the challenge for people in business and every other walk in life to acknowledge and live up to basic moral principles like honesty, respect, responsibility, fairness and caring.
