Wrongful Termination Investigations in South Dakota

01The starting point

At-Will Employment Under SDCL 60-4-4

SDCL 60-4-4, a rule carried forward from the 1877 territorial civil code, generally provides that employment with no specified term may be ended at the will of either party on notice to the other, unless a statute provides otherwise. In practice, that means an employer usually does not need a reason to let someone go. It does not mean any reason is lawful. Statutory protections such as the South Dakota Human Relations Act and federal employment law, along with contract terms, can limit at-will termination, and counsel evaluates whether any of them apply.

Because at-will is the default, a claim usually depends on evidence that the stated reason was not the real one. That evidence is factual, not legal: how comparable employees were treated, when complaints were made relative to discipline, what supervisors said to coworkers and whether written policies were followed. A wrongful termination investigation is built to find those facts. Our corporate investigations team brings experience reading personnel files and internal reports, and our page on lawful investigator methods explains the limits we follow.

02State and federal law

The Human Relations Act and the Division of Human Rights

SDCL 20-13-10 generally makes it an unfair practice to discharge, refuse to hire or treat any person, employee or intern adversely because of race, color, creed, religion, sex, ancestry, disability or national origin. The Division of Human Rights, part of the Department of Labor and Regulation and located at 123 West Missouri Avenue in Pierre, investigates and conciliates charges and refers unresolved meritorious charges to the Human Rights Commission. The Division reports that about 90 percent of its charges are employment related, with disability and race among the most common bases.

Timing is critical. Under SDCL 20-13-31, a charge with the Division generally must be filed within 180 days of the alleged practice. Federal claims under statutes such as Title VII and the Americans with Disabilities Act have their own deadlines and agency procedures, and counsel decides which forum to use. Investigators help by fixing dates precisely: the last day worked, the date of the termination notice, and when the employee first complained. Our employee background research and witness background checks support that work.

• Race, color, creed and religion
• Sex, ancestry and national origin
• Disability
• Protection extends to interns as well as employees

03Retaliation

Retaliation After a Complaint, Charge or Testimony

SDCL 20-13-26 generally prohibits reprisals, economic or otherwise, against a person who files a charge, testifies or assists in a proceeding under the Human Relations Act, and it covers threats as well as completed acts. Retaliation is among the bases the Division of Human Rights lists most often. These claims are usually proven through timing and pattern: a clean review, then a complaint, then a sudden run of write-ups. Our investigators map that sequence from documents and interviews so counsel can see whether the pattern holds up, using the same methods our investigative consulting team applies to internal reviews.

We look for the details that make a timeline credible. Who knew about the complaint, and when? Did discipline change after it? Were similar mistakes by other employees treated the same way? We interview coworkers who saw the shift, collect texts and emails that counsel can lawfully obtain, and compare scheduling and performance data where available. South Dakota is generally treated as a one-party consent state for recording, which matters when an employee recorded a meeting, and our recording law guide explains the basics.

04South Dakota workplaces

Health Systems, Card Centers, Processing Plants and Farms

South Dakota's workforce is concentrated in a few large employers and spread thinly across many small ones. In Sioux Falls, Sanford Health and Good Samaritan together employ roughly 11,000 to 11,500 people and Avera Health 9,500 to 10,000, according to the Sioux Falls Development Foundation, while Smithfield Foods employs 3,000 to 3,500 and Citi, Wells Fargo and First PREMIER each employ 1,000 to 1,500. Large employers keep extensive records and policies, which helps a wrongful termination investigation by our Sioux Falls-based investigators test whether those policies were followed.

Small employers are different. A farm operation, a family-owned dealership or a rural clinic may have no written handbook and a handful of staff who all know one another. Witnesses may still work for the employer, or be related to the owner, and may be cautious about speaking. We approach those interviews with care, explain who we work for, and document exactly what was said. Agriculture alone supports more than 132,000 jobs statewide according to a state study, so seasonal and farm workforces appear often. Our workplace investigations team understands those settings.

05Witnesses

Finding Former Coworkers Who Have Moved On

The most useful witnesses in a termination case have often left the company too. They may have taken jobs in Sioux Falls, moved to Rapid City, or crossed into Minnesota, Iowa, Nebraska or North Dakota. Some left because of the same supervisor. We locate them through public records, professional networks and lawful skip tracing, then approach them with counsel's approval and a clear explanation of the case.

Current employees present different issues. Counsel decides whether and how they may be contacted, particularly when the employer is represented, and we follow those instructions exactly. For employers, we may interview current staff as part of an internal fact-finding that counsel directs. In either situation, interviews are documented in dated memos that note who was present and what was said, so that statements can be used reliably in a Division of Human Rights proceeding or in court. Our Watertown investigators and Box Elder coverage help reach witnesses outside Sioux Falls.

06For employers

Investigations for Employers Defending a Termination

Employers and their counsel need the same facts, often sooner. When a charge arrives from the Division of Human Rights or a demand letter from a former employee's lawyer, counsel must evaluate exposure quickly and decide whether to settle, mediate or defend. We gather the facts behind the decision: who made it, what information they had, how comparable employees were treated and whether the documented reason holds up. That independent view helps counsel give realistic advice, and our compliance audit service can address any policy gaps it reveals.

Some terminations follow alleged misconduct such as theft, fraud or a false workers' compensation claim, which SDCL 62-4-51 generally makes a Class 1 misdemeanor. If the employer's reason rests on that allegation, the underlying evidence must be solid. We review video, inventory records and witness accounts, and we note weaknesses as clearly as strengths. Our workplace theft investigations and workers' compensation surveillance teams handle those underlying questions with the same documentation standard.

07Deadlines and cost

Limitation Periods, Timelines and What Investigation Costs

Several deadlines can apply after a termination, and counsel determines which ones control. The 180-day charge deadline under SDCL 20-13-31 is the shortest. South Dakota's civil limitations chapter generally allows six years for contract and other listed claims under SDCL 15-2-13, and two years for wage claims, libel and slander under 15-2-15. Defamation can arise when a former employer describes the reason for a firing to others, so we note what was said, to whom and when.

Because deadlines run quickly, we start with the documents and witnesses that answer the most important timing questions first. Employment litigation support is billed at $100 per hour with a $1,000 minimum, and the scope and price are confirmed in writing before work begins. Remote tasks such as a basic background check on a witness are $102. Counsel can review our full South Dakota service pricing and the related workplace harassment investigations page when the two issues overlap.
