SimilaritiesBoth codes are similar

Similarities
Both codes are similar insofar as they attempt to encourage specific forms of behavior by employees. Ethics guidelines attempt to provide guidance about values and choices to influence decision-making, whereas conduct regulations assert that some specific actions are appropriate or inappropriate. In both cases, the company's desire is to obtain a narrow range of acceptable behaviors from employees.
Differences
The codes attempt to regulate behavior in very different ways. Ethical standards generally are wide-ranging and non-specific, designed to provide a set of values or decision-making approaches that enable employees to make independent judgments about the most appropriate course of action. Conduct standards generally require little judgment; you obey or incur a penalty, and the code provides a fairly clear set of expectations about which actions are required, acceptable or prohibited.
