29 CFR 801.21 - Adverse employment action under security service and controlled substance exemptions.
(a) Section 8(a) (2) of the Act provides that the security service exemption in section 7(e) of the Act and § 801.14 of this part and the controlled substance exemption in section 7(f) of the Act and § 801.13 of this part shall not apply if an employer discharges, disciplines, denies employment or promotion, or otherwise discriminates in any manner against a current employee or prospective employee based solely on the analysis of a polygraph test chart or the refusal to take a polygraph test.
(b) Analysis of a polygraph test chart or refusal to take a polygraph test may serve as one basis for adverse employment actions of the type described in paragraph (a) of this section, provided that the adverse action was also based on another bona fide reason, with supporting evidence therefor. For example, traditional factors such as prior employment experience, education, job performance, etc. may be used as a basis for employment decisions. Employment decisions based on admissions or statements made by an employee or prospective employee before, during or following a polygraph examination may, likewise, serve as a basis for such decisions.
(c) Analysis of a polygraph test chart or the refusal to take a polygraph test may not serve as a basis for adverse employment action, even with another legitimate basis for such action, unless the employer observes all the requirements of section 7 (e) or (f) of the Act, as appropriate, and section 8(b) of the Act, as described in §§ 801.13, 801.14, 801.22, 801.23, 801.24, and 801.25 of this part.
