Federal law recognizes a defined set of EEO protected classes: race, color, religion, sex (which now includes sexual orientation, gender identity, and pregnancy), national origin, age 40 and older, disability, and genetic information. Equal pay between men and women doing the same work is protected separately, and so is your right to complain about discrimination without being punished for it. These protections come from Title VII of the Civil Rights Act, the Age Discrimination in Employment Act, the Americans with Disabilities Act, the Equal Pay Act, and the Genetic Information Nondiscrimination Act, all enforced by the Equal Employment Opportunity Commission (EEOC).
Race, Color, Religion, Sex, and National Origin
Title VII of the Civil Rights Act of 1964 makes it illegal for a covered employer to discriminate against a worker or applicant because of race, color, religion, sex, or national origin.1Office of the Law Revision Counsel. 42 U.S. Code 2000e-2 – Unlawful Employment Practices That covers hiring, firing, pay, promotion, assignments, and the day-to-day terms of the job.
Race and color are separate categories that overlap. An employer who rejects an applicant because of skin tone violates the color provision even when the applicant shares the employer’s racial background. Religion reaches beyond organized faiths to any sincerely held moral or ethical belief. National origin protections stop employers from making decisions based on where you were born, your accent, your ethnicity, or your cultural background; language skills can only be considered when they are genuinely relevant to job performance.
Sexual Orientation and Gender Identity
In 2020 the Supreme Court held in Bostock v. Clayton County that firing someone for being gay or transgender is sex discrimination under Title VII.2Supreme Court of the United States. Bostock v. Clayton County, Georgia The Court’s reasoning: if an employer treats a man attracted to men differently from a woman attracted to men, sex is playing a role in the decision. The ruling did not add a new category; it clarified that the existing “sex” category already covered these situations.
Religious Accommodations
For decades, an employer could refuse a religious accommodation by showing it would cost anything more than a trivial amount. The Supreme Court raised that bar in Groff v. DeJoy (2023), holding that the employer must now show the accommodation would impose a burden that is “substantial in the overall context of an employer’s business.”3U.S. Equal Employment Opportunity Commission. Religious Discrimination In practice, employers have to work harder to accommodate scheduling conflicts, dress code exceptions, and other religion-related requests before claiming hardship.
Age (40 and Older)
The Age Discrimination in Employment Act (ADEA) protects workers who are 40 or older from worse treatment because of their age in hiring, firing, pay, promotions, and terms of employment.4U.S. Equal Employment Opportunity Commission. Age Discrimination in Employment Act of 1967 A job listing seeking “recent college graduates” or capping experience at five years signals an age preference that can create legal exposure.
Age can be used as a factor when it is a genuine job requirement. Mandatory retirement ages for airline pilots and certain law enforcement roles exist because physical capacity is tied to safety. Outside those narrow exceptions, favoring younger workers is unlawful, even when the reason is that senior employees earn more.5U.S. Department of Labor. What Do I Need to Know About Age Discrimination
Disability
The Americans with Disabilities Act (ADA) protects qualified individuals with disabilities. A disability is a physical or mental impairment that substantially limits one or more major life activities such as walking, seeing, breathing, learning, concentrating, or working.6U.S. Equal Employment Opportunity Commission. Titles I and V of the Americans with Disabilities Act of 1990 Protection also covers people with a history of disability and people who are perceived as disabled even if they aren’t.
The word “qualified” carries weight. You must be able to perform the essential functions of the job, with or without a reasonable accommodation. An employer can turn away someone who genuinely cannot do the work, but not someone whose medical condition merely sounds concerning.
Reasonable Accommodations
When an employee or applicant with a disability needs a change to do the job, the employer must provide a reasonable accommodation unless it would create an undue hardship. Common examples include making workspaces accessible, modifying schedules, providing assistive equipment, restructuring non-essential duties, and reassigning someone to a vacant position.7U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship Under the ADA
A request doesn’t have to be formal or use legal terminology. Once the employer knows someone needs help because of a disability, both sides should engage in an interactive process, an informal back-and-forth to figure out what would actually work. You don’t have to name the exact solution; you just describe the problem the workplace barrier is causing. An employer that refuses to participate risks liability even if a workable accommodation existed.
The undue hardship defense lets an employer decline an accommodation that would cause significant difficulty or expense given its resources. Courts weigh the cost of the accommodation, the employer’s overall financial resources, the number of employees, and the impact on operations. A large corporation has a much harder time claiming hardship than a ten-person shop.
Pregnancy and Nursing
Pregnancy discrimination is a form of sex discrimination under Title VII as amended by the Pregnancy Discrimination Act. Workers affected by pregnancy, childbirth, or related medical conditions must be treated the same as other employees who are similar in their ability or inability to work. The Pregnant Workers Fairness Act goes further, requiring employers to provide reasonable accommodations for known limitations related to pregnancy, such as extra bathroom breaks, modified lifting requirements, or temporary schedule changes, unless the accommodation would create an undue hardship.8U.S. Equal Employment Opportunity Commission. Pregnancy Discrimination and Pregnancy-Related Disability Discrimination Penalizing someone for intending to become pregnant is discrimination as well.
Separately, the PUMP for Nursing Mothers Act requires employers to provide reasonable break time and a private space, not a bathroom, for employees to express breast milk for up to one year after a child’s birth. The space must be shielded from view and free from intrusion.9U.S. Department of Labor. FLSA Protections to Pump at Work
Genetic Information
The Genetic Information Nondiscrimination Act of 2008 (GINA) bars employers from using genetic information to make employment decisions.10U.S. Equal Employment Opportunity Commission. Genetic Information Nondiscrimination Act of 2008 The definition is broad: your genetic test results, your family members’ genetic tests, and your family medical history. Employers cannot request or purchase this information or use it to predict future healthcare costs or job performance.11U.S. Department of Labor. The Genetic Information Nondiscrimination Act of 2008 GINA
Equal Pay
The Equal Pay Act requires men and women in the same workplace to receive equal pay for substantially equal work. What matters is the actual content of the job, not the title. Every form of compensation is covered: salary, overtime, bonuses, stock options, benefits, and reimbursements. When a pay gap exists between men and women doing the same work, the employer must raise the lower wage rather than cut the higher one.12U.S. Equal Employment Opportunity Commission. Equal Pay/Compensation Discrimination
Retaliation
Retaliation is the most commonly filed charge type with the EEOC, and workers often overlook it as a protected category in its own right.13U.S. Equal Employment Opportunity Commission. EEOC Releases Fiscal Year 2020 Enforcement and Litigation Data Every federal EEO statute makes it illegal for an employer to punish you for protected activity: filing a discrimination complaint, serving as a witness in an investigation, reporting harassment to a supervisor, refusing to follow orders that would result in discrimination, or asking coworkers about pay to uncover possible wage disparities.14U.S. Equal Employment Opportunity Commission. Facts About Retaliation
The bar for a retaliation claim is lower than for the underlying discrimination claim. An employer’s action counts as retaliation if it would deter a reasonable person from asserting their rights, even when the original complaint doesn’t hold up.15U.S. Equal Employment Opportunity Commission. Retaliation – Making it Personal You don’t need legal terminology when raising concerns. As long as you reasonably believed something at work violated EEO laws, your complaint is protected.
When Harassment Crosses the Legal Line
Harassment based on any protected class becomes illegal when the conduct is severe or pervasive enough that a reasonable person would consider the work environment intimidating, hostile, or abusive. A single offhand comment usually will not meet that threshold. The law looks for patterns of behavior, or a single incident so extreme it crosses the line on its own.16U.S. Equal Employment Opportunity Commission. Harassment
Who did the harassing matters for employer liability. If a supervisor’s harassment leads to a tangible job action like termination or demotion, the employer is automatically liable. If the harassment creates a hostile environment without a tangible action, the employer can escape liability only by proving it took reasonable steps to prevent and correct the behavior and that the employee failed to use available complaint procedures. For harassment by coworkers or non-employees, the employer is liable if it knew or should have known and failed to act.
Which Employers Are Covered
Not every employer falls under every law. Title VII and the ADA apply to private employers, state and local governments, and employment agencies with 15 or more employees.17Office of the Law Revision Counsel. 42 U.S. Code 2000e – Definitions The ADEA covers employers with 20 or more employees.18Office of the Law Revision Counsel. 29 U.S. Code 630 – Definitions The Equal Pay Act applies to nearly all employers regardless of size. Federal agencies are subject to all of these laws no matter how many people they employ.
If your employer falls below the federal thresholds, don’t assume you have no protection. Many states enforce their own anti-discrimination laws with lower employee minimums, sometimes as low as one, and may cover additional categories such as marital status, political activity, or criminal history.
How to File a Charge and the Deadline
If you believe you’ve experienced discrimination based on a protected class, the first formal step is filing a charge with the EEOC. You can start online through the EEOC Public Portal, schedule an appointment at a local EEOC office, or file by mail with a signed letter describing what happened, when, and why you believe it was discriminatory.19U.S. Equal Employment Opportunity Commission. How to File a Charge of Employment Discrimination
You generally have 180 calendar days from the date of the discriminatory act to file. That deadline extends to 300 days if a state or local agency enforces a similar anti-discrimination law, which is the case in most states. Weekends and holidays count toward the deadline, but if the last day lands on a weekend or holiday, you get until the next business day.20U.S. Equal Employment Opportunity Commission. Time Limits For Filing A Charge
For ongoing harassment, the clock runs from the last incident, though the EEOC will look at the full pattern during its investigation. Separate acts of discrimination each carry their own deadline. Filing an internal grievance or pursuing outside mediation does not pause the EEOC clock.
What You Can Recover
A successful discrimination case can produce several kinds of relief. If you were denied a job or promotion, the remedy may include placement in the position with back pay and benefits. The employer must also stop the practice and take steps to prevent a repeat.21U.S. Equal Employment Opportunity Commission. Remedies For Employment Discrimination
For intentional discrimination based on race, color, religion, sex, national origin, disability, or genetic information, you may also recover compensatory damages, covering out-of-pocket costs and emotional harm, and punitive damages for particularly egregious conduct. Federal law caps the combined compensatory and punitive amount based on employer size, with the cap rising in tiers up to $300,000 for employers with more than 500 employees.22Office of the Law Revision Counsel. 42 U.S. Code 1981a – Damages in Cases of Intentional Discrimination The caps do not apply to back pay or front pay, which can be substantial on their own. Age discrimination follows a different model: instead of compensatory and punitive damages, victims of intentional age discrimination can receive liquidated damages equal to the back pay awarded. Attorney’s fees, expert witness costs, and court costs may also be recoverable.
