Age Discrimination

Age Discrimination in California Employment Law

Age discrimination occurs when an employee or job applicant is treated unfairly because of age. In California, workers age 40 and older are protected from age-based discrimination in hiring, promotions, discipline, termination, and other employment decisions.

This page explains how age discrimination claims are commonly evaluated, what evidence matters, and where claims are typically filed.

Practice Area: Employment Law Topic: Discrimination Category: Age Jurisdiction: California

Quick overview

  • Who is protected: Employees and applicants age 40 and older.
  • What is prohibited: Adverse employment actions motivated by age.
  • Where it shows up: Hiring, promotions, layoffs, discipline, pay, and termination.
This page is general information, not legal advice. An attorney cannot confirm whether age discrimination occurred in a specific situation without reviewing the facts, documents, and witnesses.

Age discrimination laws in California

California employees are protected by both state and federal law:

  • Fair Employment and Housing Act (FEHA): Prohibits age discrimination against workers age 40 and older and applies to employers with five or more employees.
  • Age Discrimination in Employment Act (ADEA): Federal law protecting workers age 40 and older at employers with 20 or more employees.

FEHA generally provides broader coverage than federal law and is commonly the primary framework for California claims.

Common forms of age discrimination

  • Hiring bias: Preferring younger candidates or excluding older applicants.
  • Layoffs and reductions in force: Disproportionate impact on older workers.
  • Promotion denials: Advancement opportunities given to younger, less experienced employees.
  • Performance scrutiny: Sudden negative evaluations or PIPs applied inconsistently.
  • Termination: Firing justified by age-related stereotypes rather than performance.

Common age-related stereotypes

  • Assumptions about adaptability or technology skills
  • Concerns about retirement or “energy level”
  • Comments about being “overqualified” or “too experienced”

How age discrimination is evaluated

Age discrimination claims are fact-driven. Analysis commonly focuses on:

  1. Protected status: Whether the employee is age 40 or older.
  2. Adverse action: Termination, demotion, pay reduction, denied promotion, or other negative treatment.
  3. Age-based connection: Evidence suggesting age was a motivating factor.
  4. Employer explanation: Whether the stated reason is consistent with documents, timing, and comparators.
An attorney cannot confirm age discrimination in a specific case without analyzing the full timeline, decisionmakers, and records.

Age-based harassment

Age discrimination may overlap with age-based harassment. Harassment analysis focuses on whether age-related comments or conduct were severe or pervasive enough to create a hostile work environment.

  • Repeated age-related jokes or insults
  • Derogatory comments about retirement or competence
  • Humiliation or exclusion tied to age

Retaliation protections

FEHA prohibits retaliation against employees who report age discrimination, participate in investigations, or oppose unlawful practices.

  • Termination or discipline after reporting concerns
  • Reduced hours or blocked advancement
  • Escalating scrutiny following complaints
Timing alone does not prove retaliation. A full fact review is required.

Evidence that often matters

  • Timeline: When age-related comments occurred relative to adverse actions.
  • Comparators: Treatment of younger employees in similar roles.
  • Documents: Performance reviews, PIPs, layoff criteria, and termination paperwork.
  • Communications: Emails, texts, or meeting notes referencing age or experience.
  • Witnesses: Coworkers or managers who observed comments or decisionmaking.
Preserve evidence without accessing systems you are not authorized to use or violating workplace policies.

Deadlines and where claims are filed

The California Civil Rights Department (CRD) states that employment discrimination complaints must generally be submitted within three years of the date you were last harmed.

CRD also requires obtaining a Right-to-Sue notice before filing a civil lawsuit.

Federal ADEA claims are typically filed with the EEOC, which describes 180-day and 300-day charge filing deadlines depending on jurisdiction.

Deadlines can vary. If timing is an issue, seek legal advice promptly.

Frequently asked questions

Does age discrimination only apply to older workers?

Under California and federal law, age discrimination protections generally apply to workers age 40 and older.

Is replacing an older worker with a younger one illegal?

Not automatically. The key issue is whether age was a motivating factor in the decision.

Can layoffs be discriminatory?

Layoffs may raise age discrimination concerns if older workers are disproportionately selected or if criteria are applied inconsistently.
