What Is a Protected Class?
Key Takeaways
- ✓A protected class is a group of people who share a characteristic that federal or state law says employers can't use to make employment decisions.
- ✓Federal protected classes come from multiple statutes: Title VII (race, color, religion, sex, national origin), ADEA (age 40+), ADA (disability), GINA (genetic information), and the Pregnancy Discrimination Act.
- ✓The EEOC received 81,055 discrimination charges in FY 2023 and secured $665 million in monetary benefits for victims.
- ✓Most federal anti-discrimination laws apply to employers with 15 or more employees. The ADEA applies at 20+. State laws often cover smaller employers.
- ✓State and local laws add additional protected classes beyond the federal list, including sexual orientation, gender identity, marital status, and criminal history in many jurisdictions.
A protected class is a group of people who share a characteristic the law says can't be held against them at work. The concept comes from the Civil Rights Act of 1964, which for the first time prohibited employers from making employment decisions based on race, color, religion, sex, or national origin. Since then, Congress has added age (40 and older), disability, genetic information, and pregnancy to the federal list. The Supreme Court's 2020 Bostock v. Clayton County decision confirmed that "sex" under Title VII includes sexual orientation and gender identity. For HR practitioners, "protected class" doesn't mean only minorities are protected. Everyone belongs to multiple protected classes. A 35-year-old white male is protected by race, sex, religion, and national origin provisions, the same as anyone else. The protection runs in every direction. What the law prohibits is using the characteristic as a factor in hiring, firing, pay, promotion, job assignment, training, or any other term and condition of employment.
Federal Protected Classes by Statute
Each federal anti-discrimination law protects specific characteristics and applies to different employer sizes. Here's the complete federal framework.
| Statute | Year | Protected Class | Employer Size Threshold | Key Provision |
|---|---|---|---|---|
| Title VII (Civil Rights Act) | 1964 | Race, color, religion, sex (including sexual orientation and gender identity), national origin | 15+ employees | Prohibits discrimination in all aspects of employment. Covers disparate treatment and disparate impact. |
| Age Discrimination in Employment Act (ADEA) | 1967 | Age (40 and older) | 20+ employees | Protects older workers from age-based decisions. Doesn't protect younger workers against preference for older workers. |
| Pregnancy Discrimination Act (PDA) | 1978 | Pregnancy, childbirth, related medical conditions | 15+ employees | Amends Title VII to clarify that pregnancy discrimination is sex discrimination. |
| Americans with Disabilities Act (ADA) | 1990 | Disability (physical or mental impairment substantially limiting a major life activity) | 15+ employees | Requires reasonable accommodations. Interactive process required when accommodation is requested. |
| Genetic Information Nondiscrimination Act (GINA) | 2008 | Genetic information (including family medical history) | 15+ employees | Prohibits use of genetic information in employment decisions. Restricts employers from requesting genetic information. |
| Equal Pay Act | 1963 | Sex (pay equity) | All employers | Requires equal pay for equal work regardless of sex. No minimum employee threshold. |
| Uniformed Services Employment and Reemployment Rights Act (USERRA) | 1994 | Military service | All employers | Protects service members from discrimination based on military service. Guarantees reemployment rights. |
State and Local Additions to Federal Protected Classes
Many states and cities extend protections well beyond the federal list. HR teams operating across multiple states must track these variations.
Sexual orientation and gender identity
While the Bostock decision extended federal Title VII protection to LGBTQ+ employees in 2020, 23 states had already passed their own protections. State laws often provide additional procedural advantages for claimants, including longer filing deadlines, lower employer-size thresholds, and the ability to file directly in state court without going through the EEOC first.
Marital and familial status
About 20 states protect against discrimination based on marital status. Some extend this to familial status (having or not having children). California, New York, and several other states include these protections. For HR teams, this means you can't factor in whether a candidate is married, single, divorced, or has children when making employment decisions in these states.
Criminal history (ban the box)
37 states and over 150 cities have adopted "ban the box" laws that restrict when employers can ask about criminal history. Some apply only to public employers; others cover private employers too. Hawaii, Illinois, and New Jersey have some of the broadest protections. The practical impact: remove criminal history questions from applications and delay background checks until after a conditional offer in covered jurisdictions.
Additional state-level classes
Other characteristics protected in various states include: political activity or affiliation (California, Colorado, New York), weight and height (Michigan, a few cities), credit history (11 states restrict use in employment), reproductive health decisions (several states post-Dobbs), hairstyle and texture (the CROWN Act in 24+ states), and cannabis use off-duty (California, New York, New Jersey, and others). The patchwork nature of state protections is one of the biggest compliance challenges for multi-state employers.
The EEOC Complaint Process
Understanding how discrimination charges are filed and processed helps HR teams respond effectively and minimize organizational exposure.
Filing a charge
An employee or applicant files a charge with the EEOC within 180 days of the discriminatory act (extended to 300 days if a state or local agency also has jurisdiction). The EEOC notifies the employer within 10 days and may request a position statement. Many charges are resolved through mediation before an investigation begins. The EEOC's mediation program resolves approximately 70% of cases that enter it.
Investigation and determination
If mediation fails, the EEOC investigates. They may request documents, conduct interviews, and visit the worksite. The investigation results in either a "cause" finding (reasonable cause to believe discrimination occurred) or a "no cause" dismissal. Even a "no cause" finding doesn't prevent the employee from filing a private lawsuit. It just means the EEOC chose not to pursue the case itself.
Right to sue
If the EEOC doesn't resolve the charge, it issues a "right to sue" letter. The employee then has 90 days to file a federal lawsuit. Employees can also request a right to sue letter if the EEOC hasn't acted within 180 days. This is common because the EEOC's backlog often means investigations take 10 months or longer.
Remedies and Damages for Protected Class Violations
The financial exposure from discrimination claims varies by statute, type of discrimination, and employer size.
| Remedy Type | Title VII / ADA | ADEA | Equal Pay Act |
|---|---|---|---|
| Back pay | Yes (lost wages from discrimination to judgment) | Yes | Yes (2-3 years) |
| Front pay | Yes (future lost earnings if reinstatement isn't feasible) | Yes | Less common |
| Compensatory damages | Yes (emotional distress, pain, suffering) with caps based on employer size | Not available (ADEA limits to economic damages) | Not available |
| Punitive damages | Yes, capped: $50K (15-100 employees), $100K (101-200), $200K (201-500), $300K (501+) | Not available under ADEA | Not available |
| Liquidated damages | Not typical | Yes (doubles back pay for willful violations) | Yes (doubles back pay) |
| Attorney fees | Yes (prevailing plaintiff recovers fees) | Yes | Yes |
| Injunctive relief | Yes (policy changes, training, monitoring) | Yes | Yes |
HR Best Practices for Protected Class Compliance
These practices reduce the risk of discrimination claims and create a defensible record when claims arise.
- Maintain a current protected class matrix for every state where you have employees. Federal protections are the floor, not the ceiling.
- Document every employment decision (hiring, promotion, termination, pay change) with objective, job-related reasons. "Wasn't a good fit" doesn't hold up. "Failed to meet the 90-day sales target of $50,000, achieving only $22,000" does.
- Train all hiring managers on what they can and can't ask in interviews. Questions about age, family plans, religion, disability, and national origin are off-limits even if the interviewer means no harm.
- Apply discipline and performance management consistently. If one employee gets a written warning for tardiness, a similarly situated employee from a different demographic should get the same consequence. Inconsistency is the single most common evidence in discrimination cases.
- Respond to every internal complaint of discrimination promptly and document the investigation thoroughly. The employer's response to a complaint often matters more in litigation than the original incident.
- Review AI hiring tools for adverse impact. The EEOC has made clear that algorithmic discrimination violates Title VII even if the bias is unintentional.
