Two employees at a large nonprofit organization recurrently have observed the Chief Recruiter for their company extend job offers to prospective employees who are members of the Chief Recruiter's ethnic group. Other, more deserving applicants routinely are rejected. The two observers both are contemplating becoming internal whistleblowers. One is a union employee who has been with the organization for 17 years and regularly receives raises in accordance his union contract. The other is a non-union employee who recently joined the organization.
Which of these employees is most likely to inform the company's Ethics and Compliance Officer?
