            (i)    the individual’s race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, genetic information, military status, or disability unrelated in nature and extent so as to reasonably preclude the performance of the employment; or

    (b)    An employment agency may not:

        (1)    fail or refuse to refer for employment or otherwise discriminate against any individual because of the individual’s race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, military status, or disability unrelated in nature and extent so as to reasonably preclude the performance of the employment; or

        (2)    classify or refer for employment any individual on the basis of the individual’s race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, military status, or disability unrelated in nature and extent so as to reasonably preclude the performance of the employment.

        (1)    exclude or expel from its membership, or otherwise discriminate against, any individual because of the individual’s race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, military status, or disability unrelated in nature and extent so as to reasonably preclude the performance of the employment;

        (2)    limit, segregate, or classify its membership, or classify or fail or refuse to refer for employment any individual, in any way that would deprive or tend to deprive the individual of employment opportunities, limit the individual’s employment opportunities, or otherwise adversely affect the individual’s status as an employee or as an applicant for employment because of the individual’s race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, military status, or disability unrelated in nature and extent so as to reasonably preclude the performance of the employment; or

        (3)    cause or attempt to cause an employer to discriminate against an individual in violation of this section.

    (d)    An employer, labor organization, or joint labor–management committee controlling apprenticeship or other training or retraining programs, including on–the–job training programs, may not discriminate against any individual in admission to, or employment in, any program established to provide apprenticeship or other training or retraining because of the individual’s race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, military status, or disability unrelated in nature and extent so as to reasonably preclude the performance of the employment.

    (e)    (1)    Except as provided in paragraph (2) of this subsection, an employer, labor organization, or employment agency may not print or cause to be printed or published any notice or advertisement relating to employment by the employer, membership in or any classification or referral for employment by the labor organization, or any classification or referral for employment by the employment agency that indicates any preference, limitation, specification, or discrimination based on race, color, religion, sex, age, national origin, marital status, sexual orientation, gender identity, disability, or military status.

        (2)    A notice or advertisement may indicate a preference, limitation, specification, or discrimination based on religion, sex, age, national origin, marital status, disability, or military status if religion, sex, age, national origin, marital status, disability, or military status is a bona fide occupational qualification for employment.

    (f)    An employer may not discriminate or retaliate against any of its employees or applicants for employment, an employment agency may not discriminate against any individual, and a labor organization may not discriminate or retaliate against any member or applicant for membership because the individual has:

        (1)    opposed any practice prohibited by this subtitle; or

        (2)    made a charge, testified, assisted, or participated in any manner in an investigation, proceeding, or hearing under this subtitle.
