What does it mean to be unethical in the workplace? It may include taking personal phone calls during your duty time; asserting that the "check is in the mail," when it is still in the making; and even stealing office supplies for personal use.
Organizations usually create an ethical standards’ code or a manual is handed over when a new employee joins, which generally lists the rules and guidelines which needs to be adhered at all times.
Many issues prevent business people from being completely ethical, consistent, and fair. Ethics is a dynamic issue and sometimes it is difficult to decide at the specific moment what is considered ethical and what is not.
