Employee Classification — Distinguish employee vs independent contractor liability

The distinction between an employee (historically called a "servant") and an independent contractor has been the cornerstone of vicarious liability doctrine for centuries. Under the common law master-servant framework, a principal who exercised the right of control over the physical conduct of another's work was deemed a "master" and could be held liable for the torts of the "servant" committed within the scope of employment. The policy rationale rested on enterprise theory: the party who benefits from the economic activity and directs the manner of its performance should internalize the costs of injuries arising from that activity. When a hiring party engaged someone who retained control over the means and methods of work—an independent contractor—the hiring party generally escaped vicarious liability because the independent contractor's autonomy broke the chain of imputed control.

The evolution of this doctrine reflects shifting economic realities. Early English common law drew rigid lines between servants working under close physical supervision and independent artisans who contracted to produce results. As the Industrial Revolution expanded the complexity of work arrangements, American courts refined multi-factor tests to accommodate diverse employment relationships. In the twentieth century, federal regulatory statutes—including the Fair Labor Standards Act, the National Labor Relations Act, and the Internal Revenue Code—each adopted their own classification frameworks, sometimes diverging from the common law test. The modern Restatement (Third) of Agency, published in 2006, reformulated the analysis while retaining the right-of-control principle as the organizing criterion.

The question this doctrine addresses remains deceptively simple: when a worker injures a third party, should the hiring party bear vicarious liability? The answer depends entirely on whether the worker is classified as an employee or an independent contractor—a determination that on the bar exam requires methodical application of the control factors to the facts presented.

The classification analysis rests on a foundation of agency law principles that interact with tort doctrines of imputed liability. Understanding these principles is essential before applying the multi-factor test, because each factor derives its significance from the overarching concept of the right to control the manner and means of work performance. The Restatement (Third) of Agency § 7.07 provides that an employer is vicariously liable for torts committed by an employee acting within the scope of employment. Critically, the doctrine turns on the right to control, not whether control is actually exercised in practice—a nuance that frequently appears on the bar exam.

The flowchart above illustrates the two-stage analysis that every bar exam question on this topic demands. At the first node, you must apply the multi-factor control test to determine the worker's classification. At the second node, the analysis diverges: for employees, the question becomes whether the tortious act fell within the scope of employment; for independent contractors, you must evaluate whether any recognized exception to the general rule of non-liability applies. Notice that the bottom bar reminds you of a point that students frequently overlook: the worker is always personally liable for the tort. The classification analysis determines only whether the hiring party also bears liability.

Courts applying the common law test do not employ a formula with weighted variables; rather, they conduct a totality-of-the-circumstances analysis guided by enumerated factors. The Restatement (Second) of Agency § 220 lists factors that remain the most frequently cited framework on bar examinations and in federal courts following Nationwide Mutual Insurance Co. v. Darden (1992). No single factor is dispositive, and the weight assigned to each varies by jurisdiction and context. However, courts consistently emphasize that the extent of control over the details of work is the master factor, with the remaining factors serving as evidentiary proxies for control.

The Restatement § 220 Factors

1. Control over the details of work — The master factor. Does the hiring party dictate how, when, and where the work is performed, or does the worker exercise independent judgment?
2. Distinct occupation or business — Does the worker hold themselves out to the public as engaged in an independent trade? An electrician with her own business card, insurance, and multiple clients suggests IC status.
3. Custom in the locality — Is the work customarily performed under supervision (employee) or without supervision (IC) in the community?
4. Skill required — Highly skilled or specialized work tends to suggest IC status because the hirer typically cannot direct the technical means of performance.
5. Tools and instrumentalities — Does the hiring party supply the tools, equipment, and workplace, or does the worker provide their own? Employer-supplied tools suggest employee status.
6. Duration of relationship — A long-term, indefinite relationship suggests employment; a fixed-term, project-based engagement suggests IC status.
7. Method of payment — Payment by the hour, week, or month suggests employee status; payment by the job or commission suggests IC status.
8. Whether work is part of the regular business — If the worker performs tasks integral to the principal's core business (e.g., a delivery driver for a delivery company), employee status is more likely.
9. Belief of the parties — Relevant but not controlling. A contract labeling someone an "independent contractor" is not dispositive; courts look to the economic reality of the relationship.

Consider the following bar exam–style fact pattern: GreenLeaf Landscaping Co. engages Marco to mow lawns and perform yard work for GreenLeaf's clients. GreenLeaf assigns Marco specific addresses each day, requires him to wear a GreenLeaf uniform, and provides the mower, trimmer, and all supplies. GreenLeaf tells Marco to arrive at 7:00 a.m. and pays him $18 per hour. Marco works exclusively for GreenLeaf and has done so for two years. While mowing a client's lawn, Marco negligently operates the mower and injures a pedestrian, Paula, on the adjacent sidewalk. Paula sues GreenLeaf for her injuries. Is GreenLeaf vicariously liable?

Even when a worker is properly classified as an independent contractor, a hiring party may still face vicarious liability under recognized exceptions. These exceptions are heavily tested on the bar exam because they complicate the seemingly bright-line rule that a hirer is not liable for an IC's torts. The three principal exceptions are the inherently dangerous activities doctrine, the non-delegable duty doctrine, and negligent hiring, supervision, or retention. Additionally, a hiring party who retains control over the specific aspect of work that causes harm may be directly liable under a retained-control theory.

The common law control test, while central to the bar exam, operates alongside distinct statutory classification frameworks that apply in regulatory contexts. Federal statutes do not uniformly adopt the Restatement test. Understanding these divergences is important for upper-level study, for multistate practice, and for appreciating how the gig economy has stressed traditional classification doctrines. The table below compares the common law test with two prominent alternative frameworks.

The rise of the gig economy has intensified pressure on traditional classification doctrine. Platform-based companies like ride-sharing services argue that their drivers are independent contractors because the drivers choose when to work and use their own vehicles. Critics counter that the platform controls pricing, routes, and customer relationships—exercising sufficient control to warrant employee classification. Several states have enacted legislation directly addressing this tension, with California's Assembly Bill 5 (2019), codifying the restrictive ABC test from Dynamex Operations West, Inc. v. Superior Court (2018), representing the most aggressive push toward broader employee classification. For bar exam purposes, however, the common law control test remains the default framework, and students should master it before exploring these statutory alternatives.
