Prohibits employers from requiring employees to sign contracts or waivers that prevent them from discussing their wages or salary, with exceptions for HR employees and supervisors with access to others' compensation information.

Bars employers from seeking prospective employees' wage or salary history from the employee or their current/former employers, except when history is public record, employee is internal candidate, or employee voluntarily discloses; employers may verify history after a job offer with compensation is negotiated.

Provides affirmative defense against equal pay violation claims for employers who completed a reasonable self-evaluation of pay practices within 3 years prior to litigation and demonstrated progress toward eliminating gender-based wage differentials.

Establishes civil fines of up to $500 per affected employee (for employers with fewer than 4 employees) or up to $2,500 per affected employee (for employers with 4 or more employees) for employers who conducted self-evaluations but failed to take steps addressing identified deficiencies.

Protects employers who did not conduct self-evaluations from negative inferences based on the absence of such evaluation.
