An employer is generally not responsible for an employee’s actions when those actions fall outside the scope of employment. Under respondeat superior, a business answers for what a worker does on the job and at least partly for the company’s benefit; once that link breaks, liability shifts to the individual. The situations that break the link are well-defined, but a few important exceptions can pull the employer back into the case even after the connection seems severed.
The Scope of Employment Test
Everything turns on this first question. The Restatement (Second) of Agency sets out four conditions, all of which must be met for conduct to fall within the scope of employment: the act was the kind of work the person was hired to do, it happened within the authorized time and place, it was motivated at least partly by a desire to serve the employer, and any use of force was not unexpected given the job.1Open Casebook. Restatement Second of Agency on Respondeat Superior When any one of those elements is missing, the employer usually walks.
The Restatement (Third) says much the same thing in plainer language: an act falls outside the scope when the employee is on “an independent course of conduct not intended by the employee to serve any purpose of the employer.”2Open Casebook. Restatement of Agency Third Excerpts A janitor who decides to rewire an electrical panel has left assigned work entirely. A salesperson who drives across town for a personal errand mid-shift has launched an independent course of conduct. In both cases, the employer has a strong argument that nothing about the act served the business.
Foreseeability sits alongside the four factors. Courts ask whether the employer could have reasonably anticipated the kind of conduct that caused the harm given the nature of the job. A delivery company can foresee a fender-bender on the route. It cannot reasonably foresee a driver abandoning the route to go shopping.
Frolic vs. Detour
Not every departure from assigned duties breaks the employment connection. Courts separate a “detour” from a “frolic.” A detour is a small, temporary side trip that keeps the worker roughly within the orbit of the job. A frolic is a major departure undertaken entirely for personal purposes. Only a frolic severs the employer’s liability.
A delivery driver who stops for coffee on the route has taken a detour. The deviation is brief, the driver is still in the general area, and the business purpose resumes almost immediately. The same driver taking the company truck to a neighboring city to visit a friend is on a frolic: the geographic departure is dramatic, the personal purpose is total, and no delivery is happening along the way. An accident during that visit falls on the driver, not the company.
What pushes a deviation from detour into frolic is some combination of distance from the assigned route, time spent away from work duties, and whether any business purpose remained during the departure. A worker who leaves their post for several hours to run personal errands has effectively suspended the employment relationship for the duration.
A Frolic Can End
One wrinkle matters for timing. If the worker finishes the personal excursion and resumes the assigned route, many courts hold that the employment relationship reactivates at that moment. The frolic defense has a narrow window, and whether the harm happened before or after the worker rejoined their duties can decide the case.
The Going and Coming Rule
A routine commute is not attributed to the employer. Under the going-and-coming rule, the employment relationship is suspended while the worker travels between home and the workplace, because during a normal commute the worker is not performing any service for the business. A car accident on the way to the morning shift is the worker’s problem, not the company’s.
The rule has real exceptions. Under the special-errand exception, if an employer asks a worker to make a stop or complete a task during the commute, the trip transforms into a work assignment, and the employment relationship is active from the moment the errand begins until the worker completes it or abandons it.
A second exception kicks in when the employer requires the worker to have a vehicle available for business use during the day. If the employer provides the vehicle or makes using a personal car an express or implied condition of employment, the commute becomes part of the job, because the employer has gained a specific business advantage from the worker’s transit. Workers who regularly travel between an employer’s office and a home office can also fall outside the standard framework, since that travel serves the business.
Purely Personal Motive
When an employee acts with no intention whatsoever to perform any part of the service they were hired for, the employer is shielded. The test looks at the worker’s state of mind at the moment of the harmful act, not at whether the act happened during business hours or at a work location.
An employee who gets into a fistfight on a business trip is a classic example. The trip itself serves the employer; the fight serves only the worker’s anger or personal grudge. Because the primary driver of the harmful conduct was personal, the employer is out, regardless of the business-trip context.
Mixed motives make the defense harder. If the conduct was at least partly motivated by a desire to serve the employer, many courts will keep the business in the case. A collections agent who threatens a debtor is doing something wrongful, but is arguably doing it in pursuit of the employer’s goal of collecting the debt. The “wholly personal” threshold matters: anything short of purely selfish motivation may not protect the employer.
Intentional Torts and Criminal Acts
As a general rule, intentional wrongdoing and criminal conduct are not attributed to the employer. A worker who assaults a customer out of personal anger, steals from a client, or commits another deliberate act for personal reasons is not advancing the business. Businesses hire people to do jobs, not to commit crimes. A retail clerk who punches a rude customer is acting on personal emotion; the store did not authorize the punch, cannot reasonably foresee it as part of cashier duties, and gains nothing from it. Criminal penalties and civil damages fall on the individual.
When Force Is Part of the Job
The analysis shifts when the role itself involves physical confrontation or the exercise of authority. Security guards, bouncers, and law enforcement officers are hired precisely because the work may require force. When one of them uses excessive force in the course of doing the job they were hired to do, courts are far more willing to hold the employer liable. The Restatement (Second) captures this: force is within the scope of employment if its use was “not unexpectable by the master” given the nature of the work.1Open Casebook. Restatement Second of Agency on Respondeat Superior A bouncer who shoves a patron too hard during an ejection may well be acting within scope. The same shove from a bookkeeper would be a clear departure.
The Foreseeability Approach to Intentional Acts
Some courts have moved away from the traditional motive test for intentional torts and instead ask whether the employment relationship itself elevated the risk of the harmful conduct. Under this approach, an employer can be held liable for an employee’s intentional act if the job created conditions that made the misconduct foreseeable, even if the employer never authorized it and the employee was not trying to serve the business. The approach matters most where employees have unsupervised access to vulnerable people, significant physical authority over others, or control over private spaces.
The Big Exception: Supervisor Harassment
Workplace harassment is the most significant carve-out from the general rule that intentional misconduct falls outside the scope of employment. Under federal law, an employer is automatically liable for harassment by a supervisor when that harassment leads to a tangible employment action such as a firing, demotion, or denial of a promotion.3U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Vicarious Liability for Unlawful Harassment by Supervisors The logic: a supervisor can only make those decisions because the company gave them the authority.
When supervisor harassment does not lead to a tangible employment action, the employer can still escape liability, but only by proving both that the company exercised reasonable care to prevent and promptly correct harassing behavior, and that the victim unreasonably failed to use the preventive or corrective procedures the company had in place.3U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Vicarious Liability for Unlawful Harassment by Supervisors A company with no harassment policy or complaint process will fail the first prong. A company with an excellent policy can still lose if a victim reported the harassment and nothing happened.
For harassment by coworkers rather than supervisors, the standard is different: the employer is liable if it knew or should have known about the misconduct and failed to take immediate corrective action.3U.S. Equal Employment Opportunity Commission. Enforcement Guidance: Vicarious Liability for Unlawful Harassment by Supervisors High-ranking officials such as company presidents or partners sit in a separate category: their harassment is automatically imputed to the employer with no affirmative defense available, because they essentially are the company.
Independent Contractors Are Not Employees
The entire framework of vicarious liability applies only to employees. If the worker is properly classified as an independent contractor, the hiring party generally is not liable for the contractor’s negligent or wrongful acts. Classification is one of the first questions a court examines in any respondeat superior case.
The IRS evaluates the relationship across three categories: behavioral control (whether the company directs what the worker does and how), financial control (who controls how the worker is paid, whether expenses are reimbursed, and who provides tools), and the type of relationship (written contracts, benefits, permanence, and whether the work is a core part of the business).4Internal Revenue Service. Independent Contractor (Self-Employed) or Employee No single factor is decisive, and what actually happens on the ground matters more than what the contract says.
On the wage-and-hour side, the Department of Labor proposed a rule in February 2026 that would replace a 2024 classification standard it stopped applying in its investigations. The proposed rule uses an “economic reality” test centered on two core factors: the degree of control the employer exercises over the work, and the worker’s opportunity for profit or loss based on their own initiative and investment.5U.S. Department of Labor. Notice of Proposed Rule: Employee or Independent Contractor Classification
One trap worth flagging: labeling a worker an “independent contractor” in a written agreement does not make it so. Courts and agencies look past the label. If the company controls the worker’s schedule, provides all the tools, and the worker performs the same tasks as regular employees, the label will not keep the court from treating the worker as an employee for liability purposes.
The Catch: Negligent Hiring, Supervision, and Retention
Even when an employee’s act clearly falls outside the scope of employment, the employer is not necessarily safe. A separate theory called negligent hiring, supervision, or retention holds the employer directly liable for its own failure to use reasonable care. This is not vicarious liability. The claim is that the employer itself was negligent in putting a dangerous person in a position to cause harm.
A negligent hiring claim typically requires showing that the employee was unfit for the position, that the employer knew or should have known about that unfitness, that the unfitness caused the harm, and that the employer’s failure to investigate or act was a substantial factor in the injury. The depth of investigation required scales with the risk the job poses to others. Hiring someone to stock shelves calls for less scrutiny than hiring someone who will enter customers’ homes or supervise vulnerable people.
This matters because it survives a successful scope-of-employment defense. A company might prove that a worker’s criminal assault on a client was a frolic, purely personally motivated, and entirely outside the scope of employment. If the company hired that worker without a background check, ignored complaints about prior misconduct, or retained the worker after learning of dangerous behavior, the company faces direct liability on a separate track. This is where most claims fall apart for employers who assume “outside the scope” means “completely protected.”
Negligent supervision works the same way. If an employer knows a worker has exhibited troubling behavior and does nothing, continued inaction can become the employer’s own negligence. Documentation decides many of these cases. An employer that investigates complaints, takes corrective action, and follows through on discipline has a strong defense. An employer that files complaints in a drawer does not.
