Revises the text of section 201(a)(1) to replace occurrences of the word "sex," with an expanded phrase that explicitly includes sexual orientation, gender identity, sex stereotype, sex characteristics, and pregnancy, childbirth, or related medical conditions.

Multiple amendments to title VII: inserts new definitions and rules of construction (including application of section 1106 to title VII), expands occurrences of the term "sex" to the longer parenthetical listing (including sexual orientation and gender identity), and adds a new codified definition and subsection making "workplace harassment" an unlawful employment practice.

Amends Title XI by redesignating existing sections and inserting a new section heading and definitions (including definitions of race, sex with the expanded parenthetical list, gender identity, and sexual orientation) and related rules immediately after the title heading.

Amends section 7 of the Age Discrimination in Employment Act (29 U.S.C. 626) to add an express limitation for 'motivating factor' claims: when an individual establishes an unlawful practice under section 4(g)(1) and the respondent demonstrates it would have taken the same action absent the impermissible motivating factor, the court may grant declaratory and injunctive relief and attorney’s fees/costs attributable only to pursuing the motivating-factor claim, but shall not award damages or order admission, reinstatement, hiring, promotion, or payment.

Amends section 15 (29 U.S.C. 633a) of the ADEA: revises subsection (a) language to re-enumerate covered entities (including military departments; executive agencies; the United States Postal Service and the Postal Regulatory Commission; units in the competitive service; the Smithsonian Institution; the Government Publishing Office; the Government Accountability Office; and the Library of Congress), alters subsections (b) and (c) by striking specified sentences, replaces subsection (g) language to align remedies with section 717 of Title VII, and adds provisions applying mixed-motive and hostile-work-environment rules to federal employee claims.

Amends section 501 of the Rehabilitation Act (29 U.S.C. 791) by adding a new subsection (h) making each department, agency, and instrumentality in the executive branch and the Smithsonian Institution liable for acts of any individual within such entity whose harassment of an individual with a disability has created or continued a hostile work environment or retaliatory hostile work environment that constitutes nonaffirmative-action employment discrimination, if at the time of the harassment the individual was authorized to undertake or recommend tangible employment actions or to direct daily work activities, or employer negligence led to the environment; subject to section 206(j).

Amends section 107 of the Americans with Disabilities Act (42 U.S.C. 12117) by adding subsection (c) ('Discriminatory motivating factor') which provides that when a plaintiff establishes a discriminatory practice under section 102(e)(1) and the respondent demonstrates it would have taken the same action in absence of the impermissible motivating factor, the court may award declaratory/injunctive relief and attorney’s fees/costs attributable only to the motivating-factor claim but shall not award damages or order admission, reinstatement, hiring, promotion, or payment.

Replaces the existing clause governing the cash wage component for tipped employees with a phased schedule: an initial cash wage of $3.60/hour for the first 1-year period beginning on the specified effective date, followed by annual increases under the new subclauses until the tipped cash wage equals the hourly wage under section 6(a)(1) for that period (with transitional rules for further increases)

Modifies the subsection to (1) change the sentence following clause (ii) so that it affirms any employee has the right to retain tips received, and (2) add an explicit employer notice requirement informing employees of that right and its exception

Adds a new subsection (h) requiring the Secretary of Labor to publish in the Federal Register and on the Department of Labor website a notice announcing any increase in the required tipped-employee wage not later than 60 days prior to the effective date of such increase; later subparagraphs schedule repeal of certain separate-tipped-wage provisions and also strike the added subsection (h) with a specified effective date tied to the tipped-wage transitions
