For a human resource management example, consider once again an employer deceiving employees about the nature of hazardous chemicals used in production. Such treatment of employees might be argued to be unfair because it violates the equal liberty principle (everyone has an equal right to be informed about all relevant aspects of employment), the equal opportunity principle (everyone has an equal opportunity to develop their talents and abilities by hard work by making well informed employment choices), and the difference principle (it fails to protect the vulnerable to the greatest extent possible).
