¶ 1. This is the second case arising from the near-fatal assault of Michael Kuligoski by Evan Rapoza, who had previously been diagnosed with schizophreniform disorder. In this case, plaintiffs-members of the Kuligoski family-brought suit against Evan's grandparents, claiming that they were liable for Evan's assault of Mr. Kuligoski while Mr. Kuligoski was repairing the furnace at their rental property. Plaintiffs claim, among other things, that the grandparents are vicariously liable for Evan's father's negligent hiring or supervision of Evan, who was there to help his father repaint an apartment.1 On appeal, plaintiffs seek reversal of the trial court's *1148order granting grandparents summary judgment. Plaintiffs argue that the court erred by determining that grandparents could not be held vicariously liable for the attack because it was not reasonably foreseeable. We affirm, but on a different basis than that relied upon by the trial court.
¶ 2. The following unchallenged facts come from grandparents' statement of undisputed facts and the trial court's order granting grandparents summary judgment. In 2009, during the summer following his freshman year in college, Evan Rapoza became ill with mononucleosis. He went back to school in upstate New York that fall but soon returned home complaining that he was tired. After returning home, he began to act oddly, was forgetful and overly dependent. That winter, Evan began counseling and treatment, but his mental condition and behavior worsened. In October 2010, his behavior toward some children prompted his mother to take him to Vermont Medical Center for admission and psychiatric evaluation.
¶ 3. Over the following month, Evan received treatment at multiple facilities. He was alternatively diagnosed with schizophreniform disorder, schizoaffective disorder, and schizophrenia. Eventually, he was admitted to the Brattleboro Retreat for five days. He was discharged from the Retreat with prescriptions for antipsychotic medication and a plan for outpatient monitoring by Northeast Kingdom Human Services. In late December 2010, a little over a month after his discharge from the Retreat, Evan told his mother that he had not been taking his medication. On February 26, 2011, Evan assaulted and severely injured Mr. Kuligoski while Evan was helping his father with work at an apartment building owned by grandparents. Evan was there because his father, who is grandparents' son, managed the property and was doing renovation work at the building for grandparents.
¶ 4. Plaintiffs commenced this action in April 2013. Their complaint contained three counts, one against Evan for assault, one against his parents for negligence in failing to supervise and control him, and one against grandparents for negligence in failing "to take reasonable steps to ensure that the[ir] property was reasonably safe for visitors there." With respect to this third remaining count, plaintiffs alleged that Evan's father, as grandparents' agent, "had a duty to effectively supervise and control Evan" and that his failure to do so "was negligence imputable to [grandparents]." They further alleged that grandparents were negligent in failing to supervise and control their son, who created an unreasonable risk to Mr. Kuligoski by bringing Evan onto the property.
¶ 5. In December 2013, following discovery that included plaintiffs deposing the parents and grandparents, grandparents filed a motion for summary judgment. Grandparents argued that, for the following reasons, they could not be held liable for Evan's attack on Mr. Kuligoski: (1) the attack was unforeseeable because at the time of the attack they did not know that Evan had mental health issues; (2) any negligence on father's part could not be imputed to them because father was an independent contractor rather than their employee; and (3) in any event, father was not negligent in supervising Evan because Evan's mental health providers did not advise him that Evan was dangerous to others.
¶ 6. In their response, plaintiffs asserted that: (1) whether grandparents knew of Evan's mental illness was irrelevant because their liability was based on the claim that Evan's father was their employee and created an unreasonable risk of danger to Mr. Kuligoski by bringing Evan onto the *1149property he managed for them; (2) grandparents failed to conclusively establish that father was an independent contractor rather than their employee; and (3) the attack was foreseeable because Evan's parents knew that Evan had violent tendencies. Plaintiffs also stated that they needed to depose mental health care professionals who had treated Evan to better respond to the question of what Evan's parents knew about Evan's violent tendencies.
¶ 7. In May 2015, after both sides filed supplemental memoranda, the trial court granted grandparents' motion for summary judgment, concluding that: (1) to the extent plaintiffs were alleging direct liability on the part of grandparents based on a claim of negligent supervision, that claim failed as a matter of law because it is undisputed that on the day of the assault grandparents were unaware of Evan's mental-health issues; and (2) notwithstanding the ambiguity as to whether father was grandparents' employee, grandparents owed no duty to Mr. Kuligoski because Evan's parents did not undertake to render services by monitoring Evan's treatment after his release from the Brattleboro Retreat and because, even assuming that father was grandparents' employee, Evan's assault against Mr. Kuligoski was not foreseeable.
¶ 8. Plaintiffs appeal that decision to this Court, arguing that the trial court erred: (1) in finding as a matter of law that Evan's attack on Mr. Kuligoski was not foreseeable; (2) in refusing to apply the doctrine of respondeat superior even though grandparents presented a case in which a jury could have reasonably concluded that father was their employee and that he negligently supervised Evan at their apartment building at a time when he knew or should have known that Evan's violent tendencies posed a risk of harm to other persons at the site; and (3) in rejecting their claim that Evan's parents undertook and breached a duty to monitor Evan's treatment after his release from the Brattleboro Retreat, thereby making Evan's assault on Mr. Kuligoski more likely.
¶ 9. Grandparents respond that: (1) they did not owe a duty of care to protect Mr. Kuligoski from unforeseeable harm resulting from Evan's assault; (2) final judgment in favor of Evan's parents bars plaintiffs' claim seeking to impute the parents' alleged negligence to grandparents; (3) policy considerations preclude imposing a duty on Evan's father to prevent Evan from harming Mr. Kuligoski; and (4) their son's alleged negligence in supervising Evan cannot be imputed to them based on their son's alleged employment relationship with them or a claim that Evan's parents undertook a duty to monitor Evan's treatment after his release from the Brattleboro Retreat.
¶ 10. On appeal, we review summary judgment rulings de novo, using "the same standard as the trial court." White v. Quechee Lakes Landowners' Ass'n, 170 Vt. 25, 28, 742 A.2d 734, 736 (1999). Summary judgment is appropriate only if the moving party "shows that there is no genuine dispute as to any material fact" and that the party "is entitled to judgment as a matter of law." V.R.C.P. 56(a). To determine whether there is any genuine dispute as to any material fact, "we accept as true any allegations made in opposition to the summary judgment motion if they are supported by affidavits or other evidentiary materials." Deutsche Bank Nat'l Trust Co. v. Watts, 2017 VT 57, ¶ 7, --- Vt. ----, 171 A.3d 392. In assessing the facts, we give the nonmoving party the benefit of "all reasonable doubts and inferences." Robertson v. Mylan Labs., Inc., 2004 VT 15, ¶ 15, 176 Vt. 356, 848 A.2d 310.
*1150¶ 11. As a preliminary matter, we reject grandparents' argument that plaintiffs' failure to appeal from the trial court's November 2015 order granting summary judgment to Evan's parents estops plaintiffs from pursing their claim imputing negligence to the grandparents. In so arguing, grandparents point to the court's statements in that order regarding plaintiffs' failure to produce facts indicating either an employment relationship between Evan and his father or the parents' awareness of the danger posed by Evan. Because Evan remained as a defendant in the case after the November 2015 order granting the parents summary judgment, there was no final judgment until Evan and his parents were dismissed from the case in August 2016 based on the parties' stipulation. Plaintiffs then timely appealed the trial court's order granting grandparents summary judgment. Thus, there is no preclusive effect arising from the court's summary judgment order in favor of the parents.
¶ 12. We now turn to the challenged order granting grandparents summary judgment based on a lack of foreseeability of the harm caused by Evan. We begin by examining the alleged employer-employee relationship between grandfather and father because we find that issue determinative.
¶ 13. Plaintiffs claim that father was negligent in hiring Evan and supervising him on the day of the attack, and that his negligence may be imputed to grandparents because of their employer-employee relationship with father. The fact that the assault occurred on grandparents' property does not necessarily make grandparents liable under the doctrine of respondeat superior. See Iverson v. NPC Int'l, Inc., 2011 SD 40, ¶ 11, 801 N.W.2d 275 ("The mere fact that the assault took place on [the owner's] property was not enough to make [the owner] liable under the doctrine of respondeat superior."). In the context of plaintiffs' claim, "[t]he doctrine establishes a principle of employer liability for the costs that work-related torts impose on third parties." Restatement (Third) of Agency § 2.04 cmt. b (2006). "Under the settled doctrine of respondeat superior, an employer or master is held vicariously liable for the tortious acts of an employee or servant committed during, or incidental to, the scope of employment." Brueckner v. Norwich Univ., 169 Vt. 118, 122-23, 730 A.2d 1086, 1090 (1999) ; see Restatement (Third) of Agency § 7.07(1) ("An employer is subject to vicarious liability for a tort committed by its employee acting within the scope of employment.").2
*1151¶ 14. Thus, to prevail on its remaining claim against grandparents, plaintiffs must demonstrate not only negligence on the part of father, but also an employer-employee relationship between grandfather and father that warrants imposing liability on grandparents for father's negligence. In the context of tort cases, we have relied upon the common law "right to control" test to determine whether a worker is an employee or an independent contractor. See Hathawayv. Tucker, 2010 VT 114, ¶ 23, 189 Vt. 126, 14 A.3d 968 ; RLI Ins. Co. v. Agency of Transp., 171 Vt. 553, 554, 762 A.2d 475, 477 (2000) (mem.); LeClair v. LeClair, 2017 VT 34, ¶ 38, --- Vt. ----, 169 A.3d 743 (stating that "essential element" in determining employer-employee relationship "is the right to control" (quotation omitted) ); see also Restatement (Third) of Agency § 7.07(3)(a) (stating that, for purposes of that section, "an employee is an agent whose principal controls or has the right to control the manner and means of the agent's performance of work").
¶ 15. "Under th[at] test, a worker is an employee if the party for whom work is being done may prescribe not only what the result shall be, but also may direct the means and methods by which the other shall do the work." Hathaway, 2010 VT 114, ¶ 23, 189 Vt. 126, 14 A.3d 968 (quotation omitted); see RLI Ins., 171 Vt. at 554, 762 A.2d at 477 ("If the party for whom the work is being done may prescribe the result, means and methods by which the other shall do the work, an employee/employer relationship is established."); cf. Watts v. Mont. Rail Link, Inc., 1999 MT 18, ¶ 11, 293 Mont. 167, 975 P.2d 283 (noting that, with respect to Federal Employers Liability Act claims, key to determining whether employer-employee relationship exists is degree of control over performance of work and manner in which it is done).3
¶ 16. The right-to-control test is the primary and generally determinative standard, but when it "does not clearly answer the question, we look to other factors to help analyze the nature of the employment relationship"-specifically, the factors set forth in § 220 of the Restatement (Second) of Agency. RLI Ins., 171 Vt. at 554, 762 A.2d at 477. Put another way, the right-to-control test is the "general standard" and "the remaining Restatement factors are supplementary to [that] test, particularly in a close case." Hathaway, 2010 VT 114, ¶ 32, 189 Vt. 126, 14 A.3d 968. In addition to "the extent of control ... over the details of the work," which is essentially the right-to-control test, the Restatement factors examine *1152whether the worker is engaged in a distinct occupation, whether the kind of occupation engaged in is usually done under the direction of an employer, the skill required, whether the worker supplies the tools for the work, the length of time the worker is employed, whether payment is by time or by the job, whether the work is part of the regular business of the principal, whether the parties believe they are creating an employer-employee relationship, and whether the principal is or is not in business. Restatement (Second) of Agency § 220(2)(a)-(j).
¶ 17. With this law in mind, we now examine the undisputed material facts concerning the relationship between grandparents and father with respect to father's work at grandparents' rental property. In 2007, grandparents, who were retired and living in Rhode Island during all relevant times, purchased as a retirement investment a two-story residential building located near their son's family in St. Johnsbury. The building had two tenants on each story. Their son, whom we refer to herein as father, acted as the property manager for his parents. At their insistence, grandparents paid him $100 per month even though he was willing to do the work for nothing. This management fee covered mowing and plowing, dealing with local vendors, and handling relations with the tenants.
¶ 18. When a tenant on the first floor moved out shortly after grandparents purchased the building, grandparents decided to undertake some renovations on that floor. Father did some of the renovation work himself, and grandparents reimbursed him for his out-of-pocket expenses and sometimes for his travel expenses. From time to time, grandparents paid father an additional hourly rate for extensive renovation work. Father sent grandparents an annual summary of the income and expenses for the building. Grandparents would also pay their daughter-in-law and grandchildren on an hourly basis when those family members occasionally helped father out with work at the building.
¶ 19. Grandparents traveled from their Rhode Island home four or five times a year to visit father and his family. When grandparents visited St. Johnsbury, sometimes grandfather would work at the apartment building along with father. Grandparents discussed with father and approved any major renovation projects on the building. When father saw something that could be corrected, he would mention it to grandparents to see if they wanted it done. In his deposition, grandfather described his interaction with his son as: you buy the materials, do the job, and tell me how much you want. Grandfather further stated that father determined what needed to be done because father was the one doing the job. Grandparents at times made decisions regarding the selection of carpets, tiles, paint, and bathroom fixtures. They did not know whether father had a regular schedule for his work at the building. Father used his own tools or tools owned by grandparents that were at the building. Father used his discretion regarding who he would take to work at the building and how he went about the work.
¶ 20. Grandparents contend that, given these undisputed facts, they were entitled to summary judgment on the basis of there being no employer-employee relationship between them and father. They argue that nothing in the summary judgment record, including the depositions of the defendants in this action, suggest that they specified the means or methods of father's work at the building. They further state that they treated father as in charge of managing the building and completing renovations he recommended as he saw fit without any direction as to his schedule or means or methods of his work.
*1153¶ 21. Plaintiffs respond that the employment relationship between grandparents and father, as well as the one between father and Evan,4 was ambiguous enough to be considered by a jury rather than determined by the court as a matter of law. In their response to grandparents' motion for summary judgment, plaintiffs argued that grandparents purchased the apartment building as a business investment, that they retained control of the business while entrusting its management to father, that they made the final decision as to renovation work, and that father used some of grandparents' equipment in doing work at the building.
¶ 22. The question of "whether or not there is a sufficient group of favorable factors to establish" an employer-employee relationship for purposes of imposing vicarious liability is generally "for the triers of fact to determine." Restatement (Second) of Agency § 220 cmt. c. But when the proffered facts demonstrate an absence of such a relationship, that determination "is made by the court." Id.
¶ 23. Here, few if any facts support finding an employer-employee relationship between grandparents and father under our primary right-to-control test. The undisputed facts show that father managed the out-of-state grandparents' building and did renovation work that he recommended without any control, or expectation of control, by grandparents over the means or methods of his work. Although grandparents, as the ones paying for the work, gave final approval for any major renovation work father recommended, father chose the means and methods to do the work without oversight. Essentially, grandparents left the management and renovation of the building to father to do as he saw fit. The fact that grandparents might choose what carpets, tiles, or fixtures would be used does not indicate that they controlled the means or methods of father's work.
¶ 24. Because this is not a close case with respect to the primary right-to-control test, we need not look at the supplementary Restatement factors. In any event, an examination of those factors overall does not indicate an employer-employee relationship between grandparents and father. Pursuant to those factors, an employer-employee relationship is indicated if, in addition to "an agreement for close supervision or de facto close supervision of the servant's work," there is
work which does not require the services of one highly educated or skilled; the supplying of tools by the employer; payment by hour or month; employment over a considerable period of time with regular hours; full time employment by one employer; employment in a specific area or over a fixed route; the fact that the work is part of the regular business of the employer; the fact that the community regards those doing such work as servants; the belief by the parties that there is a master and servant relation; an agreement that the work cannot be delegated.
*1154Id. cmt. h. Plaintiffs do not examine these factors,5 some of which suggest an employer-employee relationship while others suggest otherwise. Cf. Crawford v. Lumbermen's Mut. Cas. Co., 126 Vt. 12, 18, 220 A.2d 480, 484 (1966) (citing as "significant" in finding no employer-employee relationship "that the worker's engagement was casual, over an indefinite period, without fixed working hours and at the will and discretion of the worker"). In any event, consideration of those factors that do suggest such a relationship cannot overcome the primary right-to-control test. Application of that test, given the undisputed facts in this case, unequivocally demonstrates the lack of such a relationship between grandparents and father.6
¶ 25. Given our determination as a matter of law that no employer-employee relationship existed between grandparents and father that would subject grandparents to vicarious liability for any negligence on father's part in bringing Evan to the workplace on the day he assaulted Mr. Kuligsoki, plaintiffs' remaining claim in this lawsuit is unsustainable.7
Affirmed.
