National Origin Discrimination and English-Only Policies in South Dakota Workplaces

Across South Dakota-from large financial call centers in Sioux Falls and food processing plants in Huron and Aberdeen to bustling hospitality venues in Rapid City-multilingual workers form a vital pillar of the state economy. Yet workplace tension frequently arises when supervisors restrict employees from speaking their native language or penalize qualified staff because they speak English with a foreign accent. Because a person's primary language and speech pattern are inextricably linked to their ethnic heritage, state and federal civil rights regulators scrutinize workplace language rules with extreme care.

Neither employers nor employees can rely on casual assumptions when it comes to workplace communication rules. Under South Dakota law, requiring English proficiency where a job does not genuinely demand it-or banning workers from speaking Spanish, Somali, Karen, or Lakota during their lunch breaks-crosses the line from operational management into unlawful national origin discrimination.

Legal Framework Governing Language Restrictions and Accent Bias in South Dakota

Both state and federal statutes strictly prohibit workplace discrimination based on national origin and ancestry. At the state level, S.D. Codified Laws § 20-13-10 makes it an unfair or discriminatory practice for any employer-covering businesses with 1 or more employees under S.D. Codified Laws § 20-13-1(7)-to refuse to hire, discharge, or accord adverse treatment to any person because of national origin or ancestry. At the federal level, 42 U.S.C. § 2000e-2(a) enforces parallel protections for employers with 15 or more employees.

Crucially, South Dakota has codified an explicit administrative rule targeting language-based bias. Under S.D. Admin. R. § 20:03:11:01, covert practices of discrimination on the basis of national origin specifically include administering tests in the English language or requiring that employees and applicants read, write, or speak English when English is not the person's first language or mother tongue and when English proficiency is not a bona fide occupational requirement for the specific work to be performed.

Similarly, federal EEOC regulations at 29 C.F.R. § 1606.7 establish that a rule requiring employees to speak only English at all times in the workplace is a burdensome term and condition of employment that presumptively violates 42 U.S.C. § 2000e. Furthermore, the Eighth Circuit-whose federal rulings govern South Dakota-recognized in Hossaini v. Western Missouri Medical Center, 97 F.3d 1085 (8th Cir. 1996) and Guimaraes v. SuperValu, Inc., 674 F.3d 962 (8th Cir. 2012) that comments ridiculing an employee's foreign accent or nationality-linked speech patterns can serve as probative evidence of unlawful national origin animus.

Vulnerable Sectors: How Language and Accent Rules Apply by Industry

Whether a language policy or accent requirement is lawful in South Dakota depends heavily on the specific work environment and job duties involved.

Call Centers and Customer Service: Accent Bias from Clients and Management

Sioux Falls and Rapid City host major banking, telecommunications, and healthcare support centers. A recurring legal dispute involves qualified customer service agents who speak fluent, grammatically accurate English with a noticeable foreign accent being denied promotions or removed from phone queues because a client complained about their accent.

Under EEOC Enforcement Guidance and 29 C.F.R. § 1606.1, an employer may not base an adverse employment decision on a worker's foreign accent unless the accent materially interferes with the ability to perform job duties effectively. Merely having a discernible accent is never disqualifying if callers can understand the representative. Moreover, as the Eighth Circuit held in Bradley v. Pizzaco of Nebraska, Inc., 7 F.3d 795 (8th Cir. 1993), biased customer preference does not establish a lawful business necessity defense.

Manufacturing and Processing Plants: Safety Justifications vs. Unlawful Discrimination

In agricultural processing, meatpacking, and heavy manufacturing facilities in Sioux Falls, Huron, Watertown, and Brookings, employers often ask whether they can mandate English-only communication for workplace safety. Under 29 C.F.R. § 1606.7, a tailored rule requiring workers to speak a common language is lawful only at certain times when the employer can prove it is justified by business necessity.

For example, requiring English during active operation of hazardous machinery, chemical handling, or emergency lock-out/tag-out drills is generally lawful if clear communication among multilingual team members is necessary to prevent physical injury. However, extending that rule to quiet packing stations, warehouse corridors, or non-hazardous maintenance tasks where safety is not implicated violates both S.D. Admin. R. § 20:03:11:01 and federal law. Additionally, before enforcing any tailored rule, the employer must formally notify workers of the exact times English is required and the consequences of noncompliance.

Hospitality Workers: Bans on Speaking Native Languages During Breaks

Hotels, restaurants, and casinos across the Black Hills and eastern South Dakota sometimes implement informal policies forbidding housekeeping or kitchen staff from speaking native languages at work because coworkers or managers feel uncomfortable not understanding them. Banning employees from speaking their native language during meal periods, rest breaks, in locker rooms, or during casual personal conversations between coworkers is presumptively unlawful.

The EEOC's guidelines on national origin harassment emphasize that punishing workers for speaking their mother tongue on break-or tolerating ethnic slurs, mockery of accents, or demands to speak English in the breakroom-creates an atmosphere of inferiority, isolation, and intimidation. Under Huck v. McCain Foods, 479 N.W.2d 167 (SD Supreme Court 1991), South Dakota employers are legally obligated to take prompt remedial action to stop workplace harassment once management knows or should know it is occurring.

Step-by-Step Process for Filing a National Origin Claim in South Dakota

If you have been disciplined under an unlawful English-only rule, passed over for promotion due to your accent, or subjected to ethnic harassment, South Dakota requires you to follow a strict administrative path.

Step 1: Preserve Written Policies, Schedules, and Witness Details

Save copies of any written memos, handbook pages, breakroom signs, or text messages announcing an English-only rule or referencing your accent. Keep a contemporaneous log outside the workplace recording the dates, times, and witnesses to any ethnic slurs or disparate discipline.

Step 2: Report Internally and Guard Against Retaliation

Submit a written complaint to Human Resources or upper management following your employer's handbook procedure. Once you report suspected national origin discrimination, you are legally protected from retaliation under S.D. Codified Laws § 20-13-26. As illustrated in Leslie v. Hy-Vee Foods, Inc., 679 N.W.2d 785 (SD Supreme Court 2004), sudden negative evaluations or termination shortly after a protected complaint can establish a separate claim for unlawful reprisal.

Step 3: File a Timely Charge with the SDDHR and EEOC

As the South Dakota Supreme Court held in Matta v. Dakota Provisions, 15 N.W.3d 448 (SD Supreme Court 2024), you must exhaust administrative remedies before filing a lawsuit. Within 180 calendar days of the discriminatory act under S.D. Codified Laws § 20-13-31, submit Form DHR-1, South Dakota, Division of Human Rights, Charge of Discrimination Intake Questionnaire and execute Form DHR-2, South Dakota, Division of Human Rights, Verified Charge of Discrimination with the South Dakota Division of Human Rights, Pierre (123 W. Missouri Ave., Pierre, SD 57501; phone: 605-773-3681). Request cross-filing on Form EEOC-5, FED, U.S. Equal Employment Opportunity Commission, Charge of Discrimination with the U.S. Equal Employment Opportunity Commission, Minneapolis Area Office, Minneapolis.

Step 4: Navigate the Investigation and Exercise Litigation Rights

The Division investigates the charge under S.D. Codified Laws § 20-13-28 and provides free language interpretation if English is not your primary language. Depending on the outcome, either party may elect within 20 days of a probable cause hearing notice under S.D. Codified Laws § 20-13-35.1 to litigate in state courts such as the Minnehaha County Circuit Court, Second Judicial Circuit, Sioux Falls or the Pennington County Circuit Court, Seventh Judicial Circuit, Rapid City, or the worker may request Form EEOC-161, FED, U.S. Equal Employment Opportunity Commission, Notice of Right to Sue after 180 days to file in the U.S. District Court for the District of South Dakota, Sioux Falls.

How Much Does It Cost in South Dakota?

Workers and employers facing a national origin or language policy dispute should expect the following cost structure:

• SDDHR and EEOC Charge Filing Fee: $0.
• Language Interpreter Services at SDDHR/EEOC: $0 (provided free of charge by state and federal civil rights agencies during intake, mediation, and investigation).
• Court Filing Fees: Approximately $70 to $95 in South Dakota Circuit Court or $405 in U.S. District Court if the claim advances to a formal lawsuit.
• Employment Lawyer Fees: Many South Dakota civil rights attorneys represent employees on a 33% to 40% contingency fee basis (collecting legal fees only if they recover a settlement or judgment) or charge $225 to $400 per hour. You can connect with experienced local employment lawyers through our South Dakota directory to evaluate your policy or claim.

How Long Does the Process Take?

Employees must file their state charge within 180 calendar days of the unlawful discipline or termination (or within 300 calendar days for federal EEOC claims against employers with 15+ staff). Once filed in Pierre, voluntary mediation can resolve a dispute within 60 to 90 days, while a full neutral investigation typically takes 6 to 12 months.
