(a) It shall be an unlawful employment practice for an employer to:

(1) Fail or refuse to hire or to discharge any individual or otherwise to discriminate against any individual with respect to compensation, terms, conditions or privileges of employment because of such individual’s race, marital status, genetic information, color, age, religion, sex (including pregnancy), sexual orientation, gender identity, or national origin; or

(2) Limit, segregate or classify employees in any way which would deprive or tend to deprive any individual of employment opportunities or otherwise adversely affect the individual’s status as an employee because of such individual’s race, marital status, genetic information, color, age, religion, sex (including pregnancy), sexual orientation, gender identity, or national origin.

(3) a. For any employment-related purpose, fail or refuse to treat an employee or applicant for employment that the employer knows or should know is affected by pregnancy as well as the employer treats or would treat any other employee or applicant not so affected but similar in the ability or inability to work, without regard to the source of any condition affecting the other employee’s or applicant’s ability or inability to work;

b. Fail or refuse to make reasonable accommodations to the known limitations related to the pregnancy of an applicant for employment or employee, unless the employer can demonstrate that the accommodation would impose an undue hardship on the operation of the business of such employer;

(2) Limit, segregate or classify its membership or to classify or fail or refuse to refer for employment any individual in any way which would deprive or tend to deprive any individual of employment opportunities or would limit such employment opportunities or otherwise adversely affect the individual’s status as an employee or as an applicant for employment because of such individual’s race, marital status, genetic information, color, age, religion, sex (including pregnancy), sexual orientation, gender identity, or national origin; or

(d) It shall be an unlawful employment practice for any employer, labor organization or joint labor-management committee controlling apprenticeship or other training or retraining, including on-the-job training programs, to discriminate against any individual because of race, marital status, genetic information, color, age, religion, sex (including pregnancy), sexual orientation, gender identity, or national origin in admission to or employment in any program established to provide apprenticeship or other training.

Fail or refuse to hire or to discharge any individual or otherwise to discriminate against any individual with respect to compensation, terms, conditions, or privileges of employment because of the individual’s family responsibilities, except with respect to the employer’s attendance and absenteeism standards that are not protected by other applicable law and inasmuch as the employee’s performance at work meets satisfactory standards.

b. Limit, segregate or classify employees in any way which would deprive or tend to deprive any individual of employment opportunities or otherwise adversely affect the individual’s status as an employee because of such individual’s family responsibilities, except with respect to the employer’s attendance and absenteeism standards that are not protected by other applicable law and inasmuch as the employee’s performance at work meets satisfactory standards.

(2) This subsection does not create any obligation for an employer to make special accommodations for an employee with family responsibilities, so long as all policies related to leave, scheduling, absenteeism, work performance, and benefits are applied in a nondiscriminatory manner.

(l) Notwithstanding any other provision of this subchapter:

(1) It shall not be an unlawful employment practice for an employer to hire and employ employees, for an employment agency to classify or refer for employment any individual, for a labor organization to classify its membership or to classify or refer for employment any individual or for an employer, labor organization or joint labor-management committee controlling apprenticeship or other training or retraining programs to admit or employ any individual in any such program on the basis of religion, genetic information, age, sex (including pregnancy), sexual orientation, gender identity, or national origin in those certain instances where religion, genetic information, age, sex (including pregnancy), sexual orientation, gender identity, or national origin is a bona fide occupational qualification reasonably necessary to the normal operation of that particular business or enterprise; and

(2) It shall not be an unlawful employment practice for a school, college, university or other educational institution or institution of learning to hire and employ employees of a particular religion if such school, college, university or other educational institution or institution of learning is, in whole or in substantial part, owned, supported, controlled or managed by a particular religion or by a particular religious corporation, association or society or if the curriculum of such school, college, university or other educational institution or institution of learning is directed toward the propagation of a particular religion.

(m) Notwithstanding any other provision of this subchapter, it shall not be an unlawful employment practice for an employer to apply different standards of compensation or different terms, conditions or privileges of employment pursuant to a bona fide seniority or merit system or a system which measures earnings by quantity or quality of production or to employees who work in different locations, provided that such differences are not the result of an intention to discriminate because of race, marital status, genetic information, color, age, religion, sex (including pregnancy), sexual orientation, gender identity, or national origin, nor shall it be an unlawful employment practice for an employer to give and to act upon the results of any professionally developed ability test provided that such test, its administration or action upon the results is not designed, intended or used to discriminate because of race, marital status, genetic information, color, religion, age, sex (including pregnancy), sexual orientation, gender identity, or national origin.

(n) Nothing contained in this subchapter as it applies to discrimination because of age or sex shall be interpreted to affect or interfere with the retirement policy or system of any employer or the underwriting or administration of a bona fide employee welfare or benefit plan, provided that such policy, system or plan is not merely a subterfuge to evade the purpose of this subchapter.

(o) (1) Nothing in this subchapter shall be construed to prohibit compulsory retirement of any employee who has attained 65 years of age, and who, for the 2-year period immediately before retirement, is employed in a bona fide executive or a high policy-making position, if such employee is entitled to an immediate nonforfeitable annual retirement benefit from a pension, profit sharing, savings or deferred compensation plan, or any combination of such plans, of the employer of such an employee, which equals, in the aggregate, at least $44,000.

(2) In applying the retirement benefit test of paragraph (o)(1) of this section, if any such retirement benefit is in a form other than a straight life annuity (with no ancillary benefits), or if employees contribute to any such plan or make rollover contributions, such benefit shall be adjusted in accordance with regulations prescribed by the Secretary, United States Department of Labor, pursuant to 29 U.S.C. § 631(c)(2), so that the benefit is the equivalent of a straight life annuity (with no ancillary benefits) under a plan to which employees do not contribute and under which no rollover contributions are made.

(p) Nothing in this subchapter shall be interpreted to require employers to offer health, welfare, pension or other benefits to persons associated with employees on the basis as such benefits are afforded to the spouses of married employees.

(q) Nothing in this subchapter shall affect the ability of an employer to require employees to adhere to reasonable workplace appearance, grooming and dress standards not precluded by other provisions of state or federal law, except that an employer shall allow an employee to appear, groom and dress consistent with the employee’s gender identity.
