Equal-pay analysis turns on the work actually performed and the employer’s documented explanation—not job titles alone.

Identify the protected pay comparison

California’s Equal Pay Act (Labor Code section 1197.5) prohibits specified pay disparities based on sex, race, or ethnicity for substantially similar work, viewed as a composite of skill, effort, and responsibility and performed under similar working conditions. The comparison need not be limited to the same establishment. Begin with actual duties, decision authority, training, physical and mental demands, schedules, and working conditions rather than relying on titles.

Compare substantially similar work

Build comparator profiles from payroll records, job descriptions, performance standards, organizational charts, assignments, production data, and testimony. Compare base pay, bonuses, commissions, equity, differentials, overtime opportunities, and other compensation. Identify when the disparity began and each affected pay period. Personnel gossip or a single salary number may start an inquiry but rarely explains the complete compensation system.

Test the employer’s asserted factors

The employer may rely on a seniority system, merit system, production-based system, or bona fide factor other than sex, race, or ethnicity, subject to statutory requirements. The employer must apply its factors reasonably and account for the entire pay difference. A claimed bona fide factor must also be job related, consistent with business necessity, and not based on or derived from sex, race, or ethnicity. Check the explanation against contemporaneous records. Prior salary cannot justify a covered pay disparity.

Equal-pay claims can overlap with other employment claims, but each claim has its own requirements.

Build a paycheck-by-paycheck record

Preserve wage statements, offer letters, raises, promotion records, reviews, compensation policies, job postings, salary ranges, and communications. California limitations and recovery rules should be calculated from actual pay dates and the asserted character of the violation. Retaliation and pay-discussion protections may also matter. The final comparison should identify confirmed data, missing records, legitimate explanations, and unresolved differences.
