How U.S. Workplace Discrimination Law Protects Employees

A Single Supreme Court Decision in 2020 Transformed Employment Law for Millions

When the Supreme Court decided Bostock v. Clayton County, Georgia, 590 U.S. 644 (2020), it held that Title VII of the Civil Rights Act of 1964 protects gay and transgender employees from workplace discrimination. Justice Gorsuch's majority opinion held that firing someone for being gay or transgender necessarily involves discrimination based on sex—a characteristic Title VII explicitly prohibits. This single decision extended federal workplace protections to an estimated 11 million LGBTQ+ Americans who had previously existed in a patchwork of state-law protections. It also illustrated how a statute enacted in 1964 continues to evolve through judicial interpretation decades later.

Federal employment discrimination law comprises a cluster of statutes administered primarily by the Equal Employment Opportunity Commission (EEOC), which received 73,485 charges in fiscal year 2023.

The Federal Statutory Framework

Multiple federal statutes prohibit discrimination in different contexts and on different grounds:

Disparate Treatment vs. Disparate Impact

Employment discrimination claims fall into two fundamentally different theories, each requiring proof of different elements.

• Disparate treatment: The employer intentionally treated an employee differently because of a protected characteristic. This is the most common theory. The employer's motive is at issue. Under the McDonnell Douglas burden-shifting framework from McDonnell Douglas Corp. v. Green, 411 U.S. 792 (1973), the plaintiff first establishes a prima facie case; the burden shifts to the employer to articulate a legitimate, non-discriminatory reason; the plaintiff must then demonstrate that the employer's stated reason is pretextual.
• Disparate impact: A facially neutral policy or practice disproportionately affects a protected class without business justification. No discriminatory intent is required. Established in Griggs v. Duke Power Co., 401 U.S. 424 (1971), and codified in Title VII by the Civil Rights Act of 1991, 42 U.S.C. § 2000e-2(k). The plaintiff must identify a specific policy causing the disparity; the employer must demonstrate job-relatedness and business necessity; the plaintiff may still prevail by showing an equally effective alternative with less disparate impact.

Harassment as Discrimination

The Supreme Court held in Meritor Savings Bank v. Vinson, 477 U.S. 57 (1986) that sexual harassment constitutes sex discrimination under Title VII. Two forms of harassment are actionable:

• Quid pro quo harassment: A supervisor conditions employment benefits or threatens adverse action based on submission to sexual demands.
• Hostile work environment: Severe or pervasive conduct based on a protected characteristic that creates an abusive working environment. Conduct must be subjectively hostile to the plaintiff and objectively hostile to a reasonable person. A single severe incident—such as sexual assault—can suffice. Harris v. Forklift Systems, Inc., 510 U.S. 17 (1993).

Reasonable Accommodation Under the ADA

The ADA introduces a concept unique to disability discrimination law: reasonable accommodation. Employers must provide modifications or adjustments that enable a qualified individual with a disability to perform the essential functions of the job, unless doing so would cause undue hardship.

The accommodation process is an interactive dialogue—both employer and employee must participate in good faith. An employer's failure to engage in the interactive process, without providing an accommodation, is itself evidence of ADA violation. 29 C.F.R. § 1630.2(o)(3).

Employment discrimination law is not static. Each new Supreme Court term brings interpretations that expand or narrow protections across all covered characteristics. Workers and employers alike must track developments in this area continuously.
