Final answer:
The Office of the Inspector General is the investigative authority for EO and Sexual Harassment complaints against flag officers or SES officials, with guidelines and responsibilities set forth by the EEOC.
Step-by-step explanation:
The investigative authority for all Equal Opportunity (EO) and Sexual Harassment complaints against flag officers or Senior Executive Service (SES) officials is typically conducted by specialized entities within the government such as the Office of the Inspector General (OIG), particularly in cases involving members of the intelligence community or high-ranking officials. The process is governed by various laws, including the Civil Rights Act of 1964 and provisions set forth in 50 U.S.C. § 3033(k)(5), which relate to intelligence community whistleblowers. Inspector Generals have been granted the ability to conduct investigations regarding 'urgent concerns' as defined in the statute, including EO and sexual harassment allegations.
Additionally, the Equal Employment Opportunity Commission (EEOC) is tasked with investigating employment discrimination and is responsible for enforcing federal laws that make it illegal to discriminate against a job applicant or an employee. In the context of sexual harassment, the EEOC has defined sexual harassment and has set forth guidelines and responsibilities for employers to maintain a harassment-free workplace as mandated by the Civil Rights Act of 1964.
