Workplace Sexual Harassment Investigations in South Dakota

01The legal frame

How South Dakota and Federal Law Treat Workplace Harassment

South Dakota's Human Relations Act, SDCL 20-13-10, generally prohibits treating any person, employee or intern adversely in any term or condition of employment because of sex, among other protected characteristics. Sexual harassment is generally analyzed as a form of sex discrimination under that statute and under federal Title VII, and the Division of Human Rights publishes guidance on the subject. Whether specific conduct is unlawful is a legal question for counsel. A workplace sexual harassment investigation answers the factual questions that come first: what happened, who knew and what the employer did.

Deadlines are short. A charge with the Division of Human Rights generally must be filed within 180 days of the alleged practice under SDCL 20-13-31, and federal charges have their own deadlines. Employers that receive a complaint should act promptly, both to stop any ongoing conduct and to preserve evidence. Counsel may also want our compliance audit to review policies and reporting channels once the immediate matter is addressed, and our overview of South Dakota investigations explains how employment work fits within our wider practice.

02Why outside help

Small Employers, Family Businesses and Rural Workplaces

Many South Dakota employers are small. A dealership in a county seat, a family farm operation, a rural clinic or a seasonal lodge may have a dozen employees and no human resources department. Everyone may know everyone, and the accused person may be the owner, a spouse or a long-tenured manager whom no one feels able to question. In those settings an internal investigation is rarely seen as neutral, however well intended. An outside investigator gives the employer a process that employees can trust and that a reviewing agency can evaluate.

We start by identifying who should be interviewed, in what order, and what documents and devices may hold relevant messages. We explain our role to each witness, note who was present at each interview and record what each person said in a dated memo. When a witness worries about retaliation, we flag that concern to the employer and counsel immediately. Our Mitchell investigators and Huron coverage handle many of these matters in smaller communities, and our employee background checks can help confirm prior employment history when relevant.

03South Dakota workplaces

Hospitals, Customer Service Centers, Plants and Seasonal Tourism

Large South Dakota employers present different challenges. Health systems in Sioux Falls employ thousands, with round-the-clock shifts and complex supervisory chains. The city's credit card and banking operations grew after Citibank became a South Dakota-chartered bank in 1981, and large customer service floors bring many people into close daily contact. Food processing plants often run multiple shifts. In each, we identify the right shift supervisors, schedule interviews around rotations and arrange interpreters when needed, so the investigation reaches everyone with relevant information.

West River adds seasonal tourism. Mount Rushmore National Memorial, Badlands and Wind Cave national parks and the wider Black Hills draw summer visitors, and lodges, restaurants and attractions hire seasonal staff, many young and many living in employer housing. Complaints may surface after the season ends and witnesses have gone home. We locate them through lawful skip tracing and interview them by phone or video where appropriate. Our Spearfish team and Hot Springs coverage support Black Hills employers.

04Evidence

Interviews, Messages, Images and Recordings

Most harassment cases rest on conversations and messages. We preserve texts, chats, emails and social media posts that the employer or counsel can lawfully access, with dates, senders and context, before they are deleted. We note who else had access to shared devices or accounts. When a participant recorded a conversation, South Dakota is generally treated as one-party consent under SDCL 23A-35A-20, and our guide to recording someone in South Dakota explains what that generally allows. Any forensic copying of devices is coordinated through counsel.

Images raise criminal questions. SDCL 22-21-4, last amended in 2026, generally makes it a crime to photograph or record a person unclothed without consent and with intent to harass or harm, or to distribute such an image, and creating or distributing digitally fabricated sexual images of an identifiable person is a Class 5 felony. SDCL 22-21-1 separately addresses hidden devices in private places. When a complaint involves images or hidden cameras, we stop, preserve what is in hand and advise the employer to involve counsel and, where appropriate, law enforcement. Our cyberbullying investigations cover related digital work.

• Messages preserved with dates and senders
• Shared-device and account access noted
• Image-based conduct escalated to counsel
• Forensic copying coordinated through counsel

05After the complaint

Preventing and Documenting Retaliation

SDCL 20-13-26 generally prohibits reprisals, economic or otherwise, against anyone who files a charge, testifies or assists in a Human Relations Act proceeding, and the Division of Human Rights lists retaliation among the most common bases for the charges it receives. A complaint handled well can still become a retaliation claim if the complaining employee's schedule, assignments or reviews change afterward. We advise employers to document any job action taken during an investigation and the reason for it.

For employee-side counsel, we document the opposite: what changed after the complaint and who knew about it. Timelines showing reviews, shift changes and discipline before and after a report often decide these cases. When a termination follows, the matter may overlap with our wrongful termination investigations, and the two lines of work are coordinated so that witnesses are interviewed once. Employers that want an independent view of their reporting process can ask about our investigative consulting services.

06Safety

When Harassment Becomes Stalking or a Safety Risk

Some conduct moves beyond the workplace. SDCL 22-19A-1 generally defines stalking to include willfully, maliciously and repeatedly harassing another person by verbal, electronic, digital media, mechanical, telegraphic or written communication; a first offense is a Class 1 misdemeanor. SDCL 49-31-31 separately addresses harassing or threatening electronic communications, including spoofed caller ID. When a complaint describes following, repeated unwanted contact after work or threats, the employer's response must account for safety, not only policy.

Under SDCL 22-19A-8, a person may petition for a protection order alleging stalking, supported by a sworn affidavit of specific facts, using forms available from the clerk of the circuit court, and magistrate courts share jurisdiction over those orders. Employees decide whether to seek one, usually with their own counsel. We can document conduct lawfully so that the facts are clear, and our stalking investigations and active shooter risk audits help employers address the safety side of a serious case.

07Findings and cost

Written Findings, Timing and Cost

Our written report describes the complaint, the people interviewed, the documents reviewed and the facts we found, with each finding tied to its source. We distinguish between what was corroborated, what was disputed and what could not be determined. We do not decide whether conduct violated the law; that is for counsel and, if needed, the Division of Human Rights or a court. Employers use the report to decide on corrective action, and counsel uses it to evaluate exposure.

Timing matters, so we aim to begin interviews within days of engagement, subject to witness availability and weather when travel is required. Investigative work is billed at $100 per hour, and matters supporting litigation carry a $1,000 minimum. Every workplace sexual harassment investigation begins with a written scope and price, so the employer knows the cost before any interview. Our South Dakota rate schedule lists other services, and law firms can review our attorney engagement process.
