Vicarious liability: when an employer pays for an employee’s wrong

Vicarious liability means one person is held responsible for another person’s wrong because of the relationship between them. The most common example is an employer paying for harm an employee caused on the job. Cornell’s Wex encyclopedia, an educational secondary source, describes the doctrine of respondeat superior as one that holds an employer “legally responsible for the wrongful acts of an employee or agent” if the acts occur within the scope of the employment or agency (Wex: respondeat superior).

The employer does not have to be at fault. That sets vicarious liability apart from a claim that the employer was careless itself. This guide uses California’s official civil jury instructions as its worked example, because they lay out each step a jury decides.

Respondeat superior: the basic rule

California’s CACI No. 3700 tells jurors that an employer is responsible for harm caused by the wrongful conduct of its employees while acting within the scope of their employment (CACI 2026 edition). The same instruction adds that an employee is always responsible for harm caused by their own wrongful conduct, whether or not the employer is also liable. So an injured person can often name both.

CACI No. 3701 sets out what the injured person must prove against the employer once the employee’s wrong is established: that the worker was the defendant’s employee or agent, and that the worker was acting within the scope of that relationship when the harm happened. The underlying wrong, often ordinary negligence, is proved separately. Our guide to personal injury claims covers that part.

Scope of employment

Most disputes turn on scope. In California, CACI No. 3720 says conduct is within the scope of employment if it is reasonably related to the kinds of tasks the employee was hired to perform, or if it is reasonably foreseeable in light of the employer’s business or the employee’s job responsibilities. The plaintiff carries the burden of proof on this point.

Wex reports that jurisdictions use different tests. One asks whether an activity the employer endorsed gave the employer some benefit. Another asks whether the act is common enough to the job to be fairly called characteristic of it. The test your state uses can change the result.

Frolic vs. detour

Employees mix personal business with work all the time. The traditional labels for this are frolic and detour. Wex defines a detour as “a minor departure from an employee’s duties” that is still within the scope of employment, and a frolic as a major departure undertaken for the employee’s own benefit (Wex: frolic and detour). The employer stays liable during a detour but generally not during a frolic.

California frames the same idea as substantial deviation. Under CACI No. 3723, when an employee combines personal business with the employer’s business, the conduct stays within the scope of employment unless the employee substantially deviates. Incidental personal acts, minor delays and departures from the most direct route are treated as expected and within scope, as are acts needed for the employee’s comfort, health and convenience at work.

Employee or independent contractor

Classification matters because, as Wex puts it, respondeat superior “applies to employees, but not to independent contractors.” Wex’s entry on independent contractors says hirers usually have no vicarious liability for a contractor’s torts, with exceptions such as inherently dangerous activities, certain duties owed to specific people or the public, and premises safety obligations (Wex: independent contractor).

In California, CACI No. 3704 tells jurors the most important factor is whether the hirer had the right to control how the worker performed the work, not just the right to specify the result, and that it does not matter whether the hirer actually exercised that control. Jurors also weigh factors such as who supplied the tools and workplace, whether pay was by the hour or by the job, whether the work was part of the hirer’s regular business, whether it required specialized skill, and whether the parties believed they had an employment relationship. No single factor decides it. The job title or contract label alone does not settle the question.

Negligent hiring and supervision: a separate claim

Vicarious liability holds an employer responsible without fault. A direct negligence claim says the employer was careless itself. California’s CACI No. 426 covers negligent hiring, supervision or retention. The plaintiff must prove that the employee was or became unfit or incompetent, that the employer knew or should have known this created a particular risk to others, that the unfitness harmed the plaintiff, and that the employer’s negligence was a substantial factor in causing the harm. The instruction’s directions point to the 3700 series for claims that hold the employer liable without fault.

The difference has practical effects. A direct claim may reach conduct outside the scope of employment, and Wex notes that a hirer can be liable for its own negligent selection of, or instructions to, an independent contractor even when vicarious liability does not apply. If the injured person was also partly at fault, see our guide on comparative and contributory negligence.

Vehicle owners: a California statutory example

Some states impose liability on vehicle owners by statute. California Vehicle Code section 17150 makes an owner liable for death or injury to person or property caused by the negligent or wrongful operation of the vehicle by someone using it with the owner’s permission (Cal. Veh. Code § 17150). CACI No. 720 notes that an employer-employee relationship may support a finding of implied permission.

Section 17151(a) caps that statutory owner liability at $15,000 for injury to or death of one person in one accident, $30,000 for more than one person, and $5,000 for property damage (Cal. Veh. Code § 17151). The cap does not apply to liability arising through an employer-employee or principal-agent relationship, so an employer liable under respondeat superior is not limited by it. These figures are California’s; other states differ.

Intentional wrongs by employees

An employee who hits someone, steals, or commits another intentional wrong is not automatically outside the scope of employment. California’s CACI No. 3722 says unauthorized conduct may fall within scope if it happened during a series of acts the employer authorized, or if it arose from a risk inherent in or created by the enterprise. The instruction adds that wrongful or criminal conduct may be within the scope of employment even if it breaks a company rule or does not benefit the employer.

That does not mean every workplace assault binds the employer. The authorities collected under CACI No. 3720 explain that it is not enough that the job brought the employee and the victim together; the incident must be an outgrowth of the employment or a risk typical of the enterprise. Scope is ordinarily a question of fact for the jury.

• Identify the worker’s status. Note whether the person who caused harm was an employee, an agent or a contractor.
• Record what they were doing. Write down the time, place, task and any sign of a work errand or personal trip.
• Collect the work evidence. Uniforms, company vehicles, logos and dispatch records can show the job connection.
• Look for a direct claim. Ask whether the employer knew of past problems with the worker.
• Check state rules. Scope tests, contractor exceptions and owner liability statutes differ from state to state.
