If a company behaves underhandedly with customers and employees then it is not ethical.
If a company adamantly puts financial gain over interpretation of contracts it cannot surely be ethical. Even if their interpretation of the contract is within the law, their conduct would be “legal” rather than “ethical”.
Should a company be boastful of being “Legal”, or should they aspire to be “Ethical”?
“This above all: to thine own self be true.”
