45 C.F.R. § 73.735-306
Sexual harassment is deliberate unsolicited verbal comments, gestures, or physical contact of a sexual nature which are unwelcome. Sexual harassment is unacceptable conduct and is expressly prohibited. In addition, supervisors and managers are prohibited from taking or promising personnel actions in exchange for sexual favors, or failing to take an action because an employee or applicant for employment, refuses to engage in sexual conduct. This same prohibition applies to relationships between Department personnel who take or recommend action on a grant or contract and the grantee or contractor. Those employees who wish to file a complaint of sexual harassment should contact the Office of Equal Employment Opportunity (EEO) within their respective agencies for guidance. (Time frames for pursuing a charge alleging sexual harassment are the same as for any other complaint based on allegations of sex discrimination.)
