The 60-Second Issue Map
| Issue | What to ask | Risk / signal | Employee focus |
|---|---|---|---|
| Comparator work | Is the work substantially similar despite different titles, departments, or locations? | FOUNDATIONAL | Compare duties and responsibility, not labels alone. |
| Pay difference | Base, bonus, commission, equity, benefits, or other compensation? | HIGH | Use total compensation and period-specific data. |
| Employer factor | Seniority, merit, production, or bona fide factor other than sex, race, or ethnicity? | DEFENSE ISSUE | The factor must account for the entire differential. |
| Salary history | Was prior pay sought or used to justify current pay? | RED FLAG | Salary history alone cannot justify a disparity. |
| Transparency / retaliation | Was a posting range missing or was the employee punished for asking about or discussing pay? | SEPARATE CLAIMS | Save postings and communications. |
Five Rules That Matter
- Labor Code section 1197.5 prohibits paying employees of another sex, race, or ethnicity less for substantially similar work, subject to specified affirmative defenses.
- The comparison focuses on skill, effort, responsibility, and similar working conditions rather than identical titles or establishments.
- An employer relying on seniority, merit, production, education, training, experience, or another bona fide factor must satisfy statutory conditions and account for the entire wage differential.
- Labor Code section 432.3 restricts salary-history inquiries and requires many employers to include pay scales in job postings and provide pay-scale information upon request.
- California protects employees from retaliation for invoking equal-pay rights or discussing or inquiring about wages, subject to statutory limits.

Substantially similar work, lawful factors explaining pay differences, salary-history limits, job-posting ranges, and retaliation for discussing compensation.
What records should an employee preserve?
Useful records often include job descriptions and actual task comparisons, org charts and team assignments, pay records and compensation summaries, and job postings and advertised ranges. Preserve them lawfully and keep an accurate dated chronology.
When should an employee speak with an employment lawyer?
Compare the written plan and payroll records with the work actually performed. Repeated shortages, missing time, unlawful deductions, or changing explanations justify prompt review because wage deadlines and proof issues matter.
