Which of the following statements is true based on this scenario? An employer asked managers to identify the least productive employees without providing any guidance about how to do so. As a result, older workers were disproportionately rated as least productive. The employer has the right to fire less productive employees at will, even if it has a negative impact on older workers. Employers do not have to list distinct reasons for firing an individual based on productivity. If a person is deemed to be less productive, he or she can be fired at will. The design and administration of the practice was not reasonable because it decreased the likelihood that the employer's stated goal would be achieved and increased the likelihood that older workers would be disadvantaged.
