Leadership is the function of a leader. Leadership is also the period of time a leader spends.
According to Rath and Conchie (2009), "The most effective leaders know better than to try to be someone they are not" (pp. 79-85). This quote is only a sentence long, however it has a tremendously meaning. Leadership is the capability to conduct people with leaders that know better, rather than faking whom they are.
"What is illegal may or may not be a matter of ethics. What is ethically obligatory may be illegal. What is unethical may be legal. There is no essential connection between ethics and the law" (Paul & Elder, 2006, 13). Leadership also have to do with ethics and the law; however it is extremely important to understand and differentiate the difference of ethics and the law.
