Integrity is the following of moral or ethical principles. When someone is said to be a person of integrity, this generally means that he/she is considered to have a strong moral character. Integrity is thought by many to be one of the most important virtues a person can possess.

To have integrity, a person must base his/her actions upon a well-thought out framework of moral principles. What he/she does should be the same as what he/she says. For example, a person who speaks about the need to improve the educational system in the United States would have integrity if he/she volunteered to tutor local school children, voted for a proposal to give raises to high performing teachers, or gave money to charities that provided scholarships for deserving students.
Since integrity is closely linked with honesty, it should come as no surprise that integrity tests are routinely used by businesses throughout the United States. These tests are particularly common among those seeking to hire people for low-skilled service positions that involve much public contact, such as convenience store employees and retail clerks.
The tests claim to be able to help detect employees who would engage in counterproductive activities such as theft, tardiness, or excessive absenteeism. However, the tests are not perfect and different screening tools can often produce contradictory results.
While integrity is the following of moral or ethical principles, ethics is the development of the actual standards which are to be followed including what is right and wrong, and what is moral and immoral.
There are many ways and guidelines to determine what is ethical:
There is no clear answer to what is ethical or to what ethical behavior is. Many turn to religion or to the law to give guidance as to ethical behavior.
Individual codes of ethics are commonly seen as those unwritten rules of behavior instilled in an individual by their upbringing and environment. Society at large assumes that certain ethical behaviors are defined regardless of religion, geographic location or nationality.
Examples of societal ethical behavior can include such things as:
Tenets of a religion can also be considered to be a code of ethics. One of the most famous codes of ethics that apply to individuals is the Ten Commandments. The Ten Commandments find their roots in religion and not all of them will resonate with all people. Most people, however, can appreciate the ethical reasoning behind at least some of the Ten commandments even if they do not believe the religious teachings surrounding them:
Codes of ethics are present at all levels of society, business and individual behavior. Many are codified in writing and enforced with penalties while others are more malleable and dependent on the individual’s perception of right and wrong.
Regardless of their source or means of enforcement, codes of ethics permeate modern life and are factors to be considered in almost every facet of daily life, from proper work behavior to double parking to grabbing the daily latte. Remember, a person's integrity is based on their ability to follow these ethical and moral principles.
