Corporate codes of conduct as a method for establishing fair employment are problematic because they lack common minimum standards and ____________________.

A) Acceptable language
B) Reasonable length
C) An external enforcement mechanism
D) Their legality

Corporate codes of conduct often lack external enforcement mechanisms, which means that companies are left to monitor and enforce their own codes. This can be problematic because companies may not prioritize fair employment practices over their bottom line. Additionally, there are no common minimum standards that companies must adhere to, which can lead to inconsistencies in fair employment practices across different organizations. While language and length are also potential issues, they are not as central to the problem as the lack of an external enforcement mechanism and common minimum standards. Legality may be a concern, but it is not directly related to the issue of fair employment practices.
