Employment Discrimination Law: A Primer for US Business Owners

Employment discrimination law is among the most consequential bodies of law affecting US businesses. It governs every stage of the employment relationship, from job postings and hiring to compensation, promotion, discipline, and termination. Violations can result in compensatory damages, punitive damages, back pay, front pay, attorney’s fees, and injunctive relief. The Equal Employment Opportunity Commission receives tens of thousands of discrimination charges annually. Understanding what the law prohibits, what it requires of employers, and how to respond when a charge is filed is essential for any business with employees.

The Federal Anti-Discrimination Statutes

The primary federal employment anti-discrimination statutes are Title VII of the Civil Rights Act of 1964 (prohibiting discrimination based on race, color, religion, sex, and national origin), the Age Discrimination in Employment Act of 1967 (protecting workers 40 and older from age-based discrimination), the Americans with Disabilities Act of 1990 (prohibiting discrimination against qualified individuals with disabilities and requiring reasonable accommodation), the Pregnancy Discrimination Act of 1978 (prohibiting discrimination based on pregnancy, childbirth, or related medical conditions, as an amendment to Title VII), the Pregnant Workers Fairness Act of 2023 (requiring reasonable accommodations for workers affected by pregnancy, childbirth, or related conditions), and the Genetic Information Nondiscrimination Act of 2008 (prohibiting discrimination based on genetic information).

Title VII, the ADEA, and the ADA apply to employers with 15 or more employees (the ADEA has a 20-employee threshold). State and local anti-discrimination laws frequently apply to smaller employers and cover additional protected categories, including sexual orientation, gender identity, marital status, military or veteran status, criminal history, credit history, and others.

Sex Discrimination After Bostock

In Bostock v. Clayton County (2020), the Supreme Court held that Title VII’s prohibition on sex discrimination encompasses discrimination based on sexual orientation and gender identity. An employer who fires an employee for being gay or transgender fires that person for traits that would not have mattered but for the person’s sex, which Title VII prohibits. This ruling expanded Title VII’s coverage significantly and applies to all employers covered by the statute.

Disparate Treatment vs. Disparate Impact

Employment discrimination claims take two basic forms. Disparate treatment claims allege that an employer intentionally treated an employee or applicant less favorably because of a protected characteristic. The employer does not need to have acted with malice or animus — it is enough that the protected characteristic played a motivating role in the decision. Disparate impact claims allege that an employer’s facially neutral policy or practice has a statistically significant adverse effect on a protected group and cannot be justified by business necessity. Common examples include minimum education requirements that screen out disproportionate numbers of minority applicants, or written tests that produce adverse impact on protected groups.

Harassment as a Form of Discrimination

Workplace harassment based on a protected characteristic is a form of discrimination under Title VII and the other anti-discrimination statutes. Two forms of harassment are recognized: quid pro quo harassment (where a supervisor conditions a tangible employment benefit on the employee’s submission to sexual advances or other conduct related to a protected characteristic) and hostile work environment harassment (where conduct related to a protected characteristic is severe or pervasive enough to create an abusive working environment). Employers are strictly liable for quid pro quo harassment by supervisors. For hostile environment harassment, the employer’s liability depends on whether it exercised reasonable care to prevent and promptly correct the harassment and whether the employee failed to take advantage of preventive or corrective opportunities.

The EEOC Charge Process

Before filing a Title VII, ADEA, or ADA lawsuit in federal court, a claimant must file a charge of discrimination with the Equal Employment Opportunity Commission. The EEOC then notifies the employer and may investigate the charge. If the EEOC finds reasonable cause to believe discrimination occurred, it attempts conciliation. If conciliation fails, the EEOC may file suit on the claimant’s behalf or issue the claimant a right-to-sue letter, which the claimant uses to file their own federal lawsuit.

From the employer’s perspective, an EEOC charge is a serious matter that requires immediate action: preserving all relevant documents and records, notifying any employment practices liability insurer, reviewing the facts carefully, drafting a thoughtful position statement in response to the charge, and evaluating whether early resolution is in the employer’s interest. Many employers underestimate the importance of the EEOC charge stage and find themselves at a significant disadvantage in litigation because of decisions made (or not made) early in the process.

Proactive Compliance: What Employers Must Do

Effective compliance with employment discrimination law requires more than avoiding discriminatory decisions. Employers must post required EEO notices in the workplace, include EEO statements in job postings, conduct training for supervisors and employees on discrimination and harassment prevention, have written anti-discrimination and anti-harassment policies with clear complaint procedures, investigate complaints of discrimination or harassment promptly and thoroughly, take appropriate corrective action when discrimination or harassment is found, and avoid retaliation against anyone who complains about discrimination or participates in an investigation.

The Bottom Line

Employment discrimination law creates obligations at every stage of the employment relationship, from the job posting to the exit interview. Employers who approach employment decisions with consistent, documented, non-discriminatory processes and who take complaints seriously will be in a far stronger position when a charge or lawsuit arises. For businesses below the federal coverage thresholds, state law almost certainly creates parallel obligations — often with fewer procedural requirements before a lawsuit can be filed. Employment discrimination is not a risk that any business with employees can afford to ignore.
