How California Compares Jobs for Equal Pay

In our archived 2018 platform, we called for equal pay for equal work. For someone comparing two paychecks today, the phrase raises a practical question: what makes two jobs comparable? California law looks beyond a matching job title. It examines the actual work, the conditions under which employees perform it, and the reasons an employer gives for different compensation. A useful comparison begins with the work people do each day.

Why equal pay for equal work goes beyond job titles

Under the California Equal Pay Act, Labor Code Section 1197.5, employers generally cannot pay employees less than employees of another sex, race, or ethnicity for substantially similar work. The law views the work as a combination of skill, effort, and responsibility performed under similar working conditions. “Substantially similar” does not require identical duties.

Skill concerns the training, experience, education, and ability the position requires. Effort covers the physical or mental demands. Responsibility asks what decisions, money, people, or outcomes the employee must answer for. Working conditions include the surroundings and hazards of the job.

Consider two fictional staff members. One is called a service coordinator; the other, a customer operations specialist. If both solve similar cases, make similar decisions, and work in comparable conditions, their different titles alone do not settle whether the jobs are substantially similar. The details still need examination.

Compare the work before comparing pay

Start with descriptions of actual responsibilities rather than copying an organizational chart. A simple worksheet can reveal missing information before anyone draws conclusions about a pay disparity.

For each row, separate what you know from what you need to verify. A coworker's salary may be relevant, but guessing about their training or compensation package weakens the comparison. Two employees can have similar work with different duties in small areas; the legal question involves the work as a whole.

When a pay difference may have an explanation

California law recognizes a seniority system, a merit system, a system measuring the quantity or quality of production, and certain genuine job-related factors such as education, training, or experience. These defenses come with conditions. The employer must apply the factors reasonably, demonstrate that they account for the entire difference, and meet additional requirements for a bona fide factor. Prior salary alone cannot justify a prohibited disparity.

A longer-serving employee might earn more under a documented seniority system. That possibility does not establish that any particular difference is lawful. The employer would still need to substantiate the explanation. Conversely, a pay gap between two colleagues is not sufficient evidence by itself that the Equal Pay Act has been violated.

Comparisons can reach across departments or worksites within the same employer; they need not stop at one job classification. Still, a higher advertised salary does not disclose every relevant condition. Before drawing conclusions from a job posting, check whether the actual duties, required experience, decision-making authority, and surrounding work environment correspond to those of the employee whose pay is in question.

What employees can document and where the law is explained

Keep a factual record of your own job duties, changes in responsibilities, pay statements, job descriptions, and relevant written communications. Note when duties or pay changed. Do not obtain confidential personnel records that you are not authorized to access.

California generally protects employees who discuss their own wages, ask about colleagues' pay, or help others exercise equal-pay rights; nobody is required to disclose their own compensation. The California pay equity guidance identifies the Labor Commissioner's Office as a state enforcement authority and explains the difference between a potential concern and a supported claim.

Our historical position used a broad phrase about fairness. For a question about a specific paycheck, California's actual legal test, documented working conditions, and verified pay factors provide the more useful starting point.
