SUBSTITUTE OPINION
Our opinion issued December 20, 2001 is withdrawn. We overrule appellants’ motion for rehearing and issue this substitute opinion.
Appellants Cenobio Coronado and Ofelia Coronado, individually and as next friends of their children, Armando, Alicia, Jorge, and Anna Christina (the “Coronados”), appeal from the trial court’s take-nothing judgment entered in favor of appellee Schoenmann Produce Co. We affirm.
I. Background
Farming Technologies, Inc. (“FTI”) packages and sells potatoes through distributors under the registered trademark name of “MountainKing Potatoes.” Scho-enmann is a wholesale distributor of fruits and vegetables, including MountainKing Potatoes. FTI and Schoenmann are located in the same warehouse facility, along with several other businesses. FTI and Schoenmann are owned by the same holding company. It is undisputed that, during all times material to this case, Cenobio Coronado was an employee of FTI. Cеno-bio was injured while replacing a conveyor belt on a potato cull tank. The tank was owned and located on premises maintained by FTI. The Coronados contend Saul Flores, a co-worker employed by FTI, abandoned his assigned duties and failed to timely turn the conveyor off before Ce-nobio was injured. Cenobio’s arm was mangled when it was pulled between two rollers.
The Coronados maintain that Cenobio was an employee of both FTI and Schoen-mann at the time of the accident. This contention is based mainly on the assertion that FTI and Schoenmann both had the right to control Cenobio’s work. 1 The Co- *745 roñados filed suit against Schoenmann alleging negligence and gross negligence based solely on breach of an employer’s legal duties. Subsequently, the Coronados added FTI as a defendant. FTI filed, and the trial court granted, a motion for summary judgment based on limitations. 2 The issue аt trial was whether Cenobio was an employee of both Schoenmann and FTI. The trial was bifurcated, with the issue of whether Cenobio was an employee of Schoenmann at the time of the accident to be tried first. FTI’s status as Cenobio’s employer was previously determined by another court. 3
When the Coronados rested their case after presenting evidence on the joint control issue, Schoenmann moved for a directed verdict. The trial court granted Scho-enmann’s motion, finding no evidence in the record that: (1) Schoenmann employed Cenobio at the time of the accident; (2) Cenobio was acting in the course and scope of employment with Schoenmann at the time of the accident; (3) Saul Flores was acting as an employee of Schoenmann at the time of the accident; and (4) Flores was acting in the course and scope of employment with Schoenmann at the time of the accident.
II. Appellants’ Issues
On appeal, the Coronados contend the evidence shows: (1) Schoenmann and FTI exercised joint control over Cenobio and other FTI workers at the time of his work-related injury; (2) Schoenmann ex-erased persistent supervisory control over Cenobio and other FTI workers at the time of his work-related injury; and (3) there was a significant overlap in the supervisory ranks of Schoenmann and FTI at the time of his work-related injury. As a preliminary matter, Schoenmann contends the Coronados have waived three of the grounds on which the directed verdict was based. Schoenmann asserts the Co-ronados have only addressed the ground regarding whether Schoenmann employed Cenobio at the time of the accident, but did not address the other three grounds. We conclude that the Coronados have not appealed thе points pertaining to Flores’s status as a Schoenmann employee. With respect to the ground that Cenobio was not acting in the course and scope of employment with Schoenmann, we find the Coronados have not waived that ground on appeal. Rule 38.1(e) of the Texas Rules of Appellate Procedure provides “[t]he statement of an issue or point will be treated as covering every subsidiary question that is fairly included.” Courts are further directed to liberally construe appellate briefing rules.
Tex. Mexican Ry. Co. v. Bouchet,
*746 III. Standard of Review for Directed Verdict
A directed verdict is proper when: (1) a defect in the opponent’s pleading renders it insufficient to support a judgment; (2) the evidence cоnclusively proves a fact that establishes a party’s right to judgment as a matter of law; or (3) the evidence offered on a cause of action is insufficient to raise an issue of fact.
Knoll v. Neblett,
IV. Test For Employee-Employer Relationship
The Coronados seek to impose upon Schoenmann the non-delegable duty of an employer to provide a safe place to work; therefore, it is their burden to show that Cenobio was an employee of Schoen-mann at the time of his injury.
See Anchor Cas. Co. v. Hartsfield,
The issue of whether Schoenmann was Cenobio’s employer at the time of his injury is complicated by the Coronados’ claim that FTI and Schoenmann were Cenobio’s joint employers at the time of his injury. The Coronados contend they presented evidence sufficient to raise a material fact issue on FTI’s and Schoenmann’s concurrent control over Cenobio’s work at the time of his injury. Here, there is no express contract of employment between Ce-nobio and Schoenmann establishing either Cenobio’s status as a Schoenmann employee or Schoenmann’s right to control the details of his work. The Coronados claim, in the absence of such a contract, they *747 have presented evidence of Schoenmann’s “actual and persistent” exercise of control over Cenobio and other FTI workers, thereby establishing Schoenmann as Ceno-bio’s joint employer.
Y. The Joint Employer Doctrine
In support of their argument that Schoenmann was Cenobio’s joint employer, the Coronados rely on section 226 of the Restatement (Second) of Agency, which provides:
A person may be the servant of two masters, not joint employers, at one time as to one act, if the service to one does not involve abandonment of the service to the other.
Restatement (Secоnd) of Agency § 226 (1958). They also cite three lines of cases to support their theory that the joint employer doctrine should be applied in this ease: (1) application of the doctrine where a purported joint employee caused injury to a third party; (2) application of the doctrine to staff leasing services in the workers’ compensation context; and (3) application of the doctrine under the Federal Employers’ Liability Act (“FELA”). However, the Coronados’ cited cases are factually distinguishable. Here, the Coro-nados are pursuing a common-law negligence cause of action for breach of non-delegable duties owed by employers to employees. 4 Uniquely, the Coronados seek recovery from multiple, alleged employers who elected not to purchase workers’ compensation coverage.
A. Third-Party Liability Cases
First, the Coronados cite cases in which courts applied the joint employer doctrine where a purported joint employee caused injury to a third party.
See White v. Liberty Eylau Sch. Dist.,
Before the Restatement of Agency was written, the Court of Civil Appeals addressed employer liability under the joint employer doctrine in
W. Union Telegraph,
Later, in
Gulf,
the Texarkana court cited section 226 as authority for imposing joint liability against two employers for injuries to a third party.
Similarly, in
Liberty Eylau,
the court specifically adopted section 226 in holding that one could be the employee of joint employers when an injured third party attempts to impose liability on both employers.
Therefore, Texas courts have consistently adopted and applied section 226 when a third party asserts liability against two оr more employers under the doctrine of respondeat superior. 6 Section 226 should be applied in such instances; however, as discussed below, many courts have applied it to cases that did not involve liability of a principal to third parties. Our survey of case law indicates that we may be the first court to acknowledge the obvious; section 226 is included in that portion of the Restatement of Agency entitled:
Chapter 7. Liability Of Principal To Third Person; Torts
Topic 2. Liability For Authorized Conduct Or Conduct Incidental Thereto
Title B. Torts Of Servants
Who Is A Servant.
Further, we also may be the first court to acknowledge that section 226 expressly does not apply to joint employers: “A person may be the servant of two masters, not joint employers, at one time as to one act.... ” See Restatement (Second) op Agency § 226 (emphasis added). A two-party action is in play when a purported employee pursues a cause of action for negligence against his purported employer(s). A three party action is in play when a plaintiff pursues an action against an employee/agent of two or more principals/employers. Accordingly, we conclude that section 226 is properly applied only when a third party asserts vicarious liability against two or more employers.
B. Staff Leasing Cases
The Coronados also rely on
Brown v. Aztec Rig Equip. Inc.,
We held that Administaff and Aztec were Brown’s co-employers and both were immune from suit under the exclusive remedy provisions of the workers’ compensation laws.
Id.
at 847. We cited section 226 and several cases that have purportedly acknowledged the joint employer doctrine in the workers’ compensation context.
See id.
at 843-44 (citing
Insurors Indem. & Ins. Co. v. Pridgen,
We also noted in
Brown
that the Texas Legislature expressly recognizes co-employer status for purposes of workers’ compensation in staff leasing services.
Id.
at 846-47. The Staff Leasing Services Act (“SLSA”) governs staff leasing services.
See
Tex. Lab.Code Ann. § 91.001-91.063 (Vernon 1996 and Supp.2003). Under the
*750
SLSA, a staff leasing company may elect to obtain workers’ compensation coverage for its employees.
See
Tex. Lab.Code Ann. § 91.042(a) (Vernon 1996). The staff leasing company and its client company are “co-employers” for workers’ compensation purposes.
See
Tex. Lab.Code Ann. § 91.042(c) (Vernon 1996). If the staff leasing company elects to obtain workers’ compensation coverage, then recovery of workers’ compensation benefits is an injured employee’s exclusive remedy, and he is barred from asserting a claim against either the staff leasing or the client company for injuries sustained during the course and scope of employment.
See
Tex. Lab. Code Ann. §§ 91.042(c), 406.034, 408.001 (Vernon 1996). However, if the staff leasing company does not purchase workers’ compensation coverage, an employee may pursue a common-law negligence cause of action against the leasing company and its client company, and they cannot assert traditional defenses.
See
Tex. Lab.Code Ann. §§ 91.042(d), 406.004, 406.038 (Vernon 1996
&
Supp.2003). Therefore, our
Brown
decision was based in part on the fact that SLSA mandates co-employer status in staff leasing services.
See Brown,
In
Texas Workers’ Comp. Ins. Fund v. Del Indus. Inc.,
C. FELA Cases
Finally, in support of their contention that the joint employer doctrine applies in this case, the Coronados rely on a fine of federal cases decided under FELA, 45 U.S.C.A. §§ 51-60 (1986).
See Kelley v. S. Pac. Co.,
In
Kelley,
the court applied section 226 and stated that one may be an employee of a railroad under FELA while also employed by another.
13
Kelley,
VI. Joint Employee Doctrine Not Applicable When Purported Employee Pursues Common-Law Negligence Claim Against Two or More Non-Subscribers
Texas is unique in American jurisprudence because it is the only state that
*752
allows an employer to reject statutory workers’ compensation insurance.
See Lawrence v. CDB Serv., Inc.,
The Coronados do not cite, and we have not found, a case in which a Texas court has applied section 226 and the joint employer doctrine when a purported employee pursues a common-law negligence claim against two or more non-subscribers. We decline to do so now because application of the joint employer doctrine in such cases is inequitable and problematic.
The Texas Legislature has enacted specific rules apportioning liability between joint tortfeasors according to each tortfea-sor’s assigned percentage of responsibility. Tex. Civ. PRAC. & Rem.Code Ann. §§ 33.013, 33.015 (Vernon 1997). The Legislature has also determined that a joint tortfeasor is not jointly and severally hable for causing a claimant’s injury unless its share of liability is greater than fifty percent. Tex. Civ. Prac. & Rem.Code Ann. § 33.013(b). As an exception, in cases involving environmental and toxic torts, a joint tortfea-sor is jointly and severally liable if its share of responsibility is equal to or greater than fifteen percent. Tex. Civ. Prac. & Rem.Code Ann. § 33.013(c). Further, the amount of damages awarded are reduced by the claimant’s percentage of responsibility, if any. See Tex. Civ. Prac. & Rem. Code Ann. § 33.012(a) (Vernon 1997).
However, these rules do not apply to non-subscribers in an employee’s negligence action because they are barred from asserting comparative responsibility.
See Kroger,
Instead, the entity that creates and directly controls the circumstances giving rise to the risk of injury should bear the liability. Only the non-subscriber controlling the
details
of the work at the time of the injury should be subjected to 100% liability for any degree of negligence that causes injury to a worker.
See Newspapers,
VII. The Borrowed Servant Doctrine
Texas courts have long recognized that a general employee of one employer may become the borrowed servant of another.
Sparger v. Worley Hosp., Inc.,
For liability purposes, where one entity “borrows” another’s employee, workers’ compensation law identifies one party as the “employer” and treats all others as third parties.
Smith,
*754
To achieve consistency and predictability in the law, the borrowed servant doctrine should be applied to both subscribers and non-subscribers.
See Sparger,
Consistent with the borrowed servant doctrine, we hold that the non-subscriber controlling the details of an employee’s work at the time of injury should be the only entity bearing the nondelega-ble duty to provide a safe place to work.
See McKay,
Very high authority has said, in effect, “No man can serve two masters.” This principle is fundamental in the law of master and servant. There cannot be more than one responsible superior for the same subordinate at the same time and in the same transaction. When it is conceded one is the servant of one of two or more persons, it is sometimes difficult to tell who is the master. In modern industry the line of cleavage is often difficult of ascertainment. Before one is the master he must have the right *755 and power to control the servant in the particular work in hand, however temporary may be that right and power.
Alexander,
Accordingly, we reject application of section 226 and the joint employer doctrine when a purported employee pursues a common-law negligence claim against two or more non-subscribers unless joint employment is authorized by statute 17 or the subject of a contract. 18
VIII. Right To Control Details Of Cenobio’s Work At The Time Of His Injury
The pivotal issue is whether Sehoenmann, and not FTI, had the right to control the details of Cenobio’s work at the time of his аccident.
19
The Coronados claim overlap in the supervisory ranks establishing Sehoenmann’s right to control Cenobio’s work at the time of the accident is demonstrated by Gerald Farrell’s dual role as vice president of FTI and general manager of both Sehoenmann and FTI. Farrell had the right to control FTI employees as long as he went through the employee’s supervisor. Lee Odale, FTI’s maintenance supervisor, was Cenobio’s direct supervisor. Odale’s immediate supervisor was Farrell. Odale testified that when he had questions, he asked Farrell. The Coronados argue a reasonable inference exists that, as Odale’s supervisor, Farrell provided supervisory instruction regarding Cenobio’s repair of the cull tank. The
undisputed
evidence establishes that no one instructed Odale to replace the damaged belt on the cull tank. Instead, he noticed the damaged belt and instructеd Cenobio to replace it.
See Gonzales v. Hearst Corp.,
Anthony Colunga, as FTI’s plant manager, controlled Cenobio’s work on occasion. The Coronados refer to testimony that Co-lunga went to Farrell for instruction and guidance. Based on this testimony, the Coronados contend a reasonable inference exists thаt Farrell instructed Colunga regarding repair of the cull tank. Colunga, in turn, supervised Cenobio when Odale told Cenobio to ask Colunga for additional personnel to assist replacing the belt. The Coronados, however, have taken this isolated testimony out of context. Colunga continued to explain that he went to Pat Goolsby, president of FTI, if he had a question concerning the operation of the line and only went to Farrell regarding personnel issues. In any event, we cannot conclude from this evidence that Farrell provided any instruction to Colunga regarding replacement of the belt on the cull tank.
The Coronados contend Schoenmann’s right of control is further shown by Mark Steakley’s service as vice president, general counsel, and chief financial officer of Schoenmann, as well as officer in charge of safety for FTI. The Coronados argue that Steakley witnessed the accident; therefore, it can be reasonably inferred that he was, in his role as an employee of Schoen-mann, directly overseeing Cenobio’s replacement of the belt on the cull tank.
20
Steakley’s testimony on this point was equivocal, and we cannot draw a reasonable inference from his mere view of the accident, if indeed he saw it happen, that he was exercising the right to control details of Cenobio’s work. Other than evidence of his overlapping duties between Schoenmann and FTI, there is no evidence that Steakley was exercising control over the details of Cenobio’s work at the time of the accident. The Coronados further assert that it was Steakley’s responsibility to investigate the accident. Any actions taken after the accident, however, are not relevant to determining control at the time of the injury.
See Archem Co.,
The Coronados point to additional evidence of overlap of supervisory personnel. For example, when Cenobio applied for a job, he went through Schoenmann’s personnel office. The record indicates Scho-enmann hired workers for both Schoen-mann and FTI. Although Cenobio’s job application is on an FTI letterhead, it was approved by both Farrell, general manager of Schoenmann and FTI, and Colunga, plant manager for FTI. In addition, Cenobio was issued a safety manual showing Schoenmann’s and FTI’s names on the cover. Finally, the Coronados argue that despite Schoenmann’s evidence *757 that it did not use the cull tank, it nonetheless would have benefitted from Ceno-bio’s replacing the belt because of the interdependence of the two businesses. At most, the Coronados presented some evidence of overlapping supervisory duties and joint administrative functions between Schoenmann and FTI. Such evidence, however, is not sufficient to raise a fact issue whether Schoenmann exercised control over the details of Cenobio’s work (replacement of the belt on the cull tank) at the time he was injured.
IX. Conclusion
The Coronados elected to pursue Scho-enmann solely under the theory that Scho-enmann was Cenobio’s joint employer at the time of his injury. However, under our analysis and application of Texas law, evidence of a general right of control is not sufficient to impose liability on multiple employers for breach of the nondelegable duty to provide a safe place to work. The Coronados could have pursued third party claims against multiple persons or entities having a general right of control over the work environment; however, a cause of action for breach of duties owed by employers to employees may be asserted only against the entity that had the right to control details of Cenobio’s work at the time of injury.
We find the Coronados failed to present any evidence of probative value sufficient to raise a fact issue that Schoenmann had the right to control the details of Cenobio’s work (replacement of the belt on the cull tank) at the time of the accident. Therefore, the trial court properly granted a directed verdict in favor of Schoenmann. All of the Coronados’ issues are overruled. Accordingly, we affirm the judgment of the trial сourt.
Notes
. The Coronados pleaded that FTI and Scho-enmann were engaged in a single business enterprise as an alternative theory under *745 which to hold Schoenmann liable; however, this issue was not tried.
. FTI is not a party to this appeal.
. After Cenobio filed suit and signed an affidavit stating he was employed by Schoen-mann at the time of the accident, FTI filed a declaratory judgment action in the United States District Court. FTI sought a determination as to Cenobio’s employment status and reimbursement of approximately $300,000 paid under its Voluntary Employee Injury Benefit Plan. The District Court found Ceno-bio's injury occurred in the course and scope of employment with FTI. Schoenmann contends this ruling collaterally estopped the Co-ronados from denying that Cenobio was FTI’s employee and from claiming Cenobio was Schoenmann's "borrowed servant" at the time of the injury. Appellants do not contend that Cenobio was Schoenmann’s borrowed servant.
. It is well established that an employer has certain nondelegable and continuous duties to his employees.
Leitch v. Hornsby,
. The Coronados also rely on
Worley Hosp., Inc. v. Caldwell,
. Under the doctrine of respondeat superior, an employer is vicariously liable for the negligence of an agent or employee acting within the scope of his or her agency or employment, although the principal or employer has not personally committed a wrong.
See Baptist Mem’l Hosp. Sys. v.
Sampson,
. In
Pridgen,
a dispute arose over which of three workers’ compensation carriers must pay benefits to the widow of a worker killed while working on a dragline at a shipyard. The widow claimed the deceased was an employee of the shipyard, the drаgline operator, and another company that arranged for the dragline operator to provide the dragline to the shipyard.
. In
Thate,
an injured worker who recovered workers' compensation benefits from his employer’s carrier also sought FELA benefits from a railroad.
. In
Assoc. Indem. Co.,
the workers' compensation carrier for a temporary employment company sought reimbursement for benefits paid to an employee injured while working for the employment company’s customer.
. In
Callaway,
the court, without discussing the joint employer theory, upheld a jury finding that a workers’ compensation claimant was injured in the course and scope of his employment for two employers.
. The SLSA was not in effect when Brown was injured; however, we cited the fact that the SLSA now recognizes co-employer relationships in staff leasing services as one reason for our conclusion that Aztec and Admin-istaff were Brown’s co-employers. Id. at 847.
. We recognize there has been some confusion among the courts as to the extent of our holding in
Brown.
Some courts have cited
Brown
as generally supporting the joint employer doctrine within a workers’ compensation setting.
See, e.g., Garza v. Excel Logistics, Inc.,
_ S.W.3d _, _,
. The question of master-servant status under FELA is to be determined by reference to common-law principles.
Kelley,
.
See, e.g„ Kelley,
. In
Ortiz,
the plaintiff was assigned by S & M Cleaning to clean floors at Furr’s, where he was assaulted by two of Furr’s employees.
. Section 226 of the Restatement of Agency was adopted after Alexander. Because section 226 specifically provides that one may have two masters, we do not imply that the principle "no man can serve two masters” is applicable when a third party attempts to impose vicarious liability on both masters. The Alexander court addressed employer liability to an employee, and we apply the principle "no man can serve two masters,” cited therein, only to employee versus employer liаbility.
.
See, e.g.,
FELA, 45 U.S.C.A. §§ 51-60;
Kelley,
. Two or more subscribers may contractually agree to be joint employers. However, we do not address that situation because there is no such agreement in this case. We limit our ruling to situations in which an injured worker alleges two or more nonsubscribers are his joint employers in order to impose the non-delegable duties of an employer on both.
. Sehoenmann asserts that the Coronados are collaterally estopped from claiming that Sehoenmann was Cenobio’s employer at the time of the injury because a United States District Court has previously ruled that his injury occurred while in the course and scope of his employment for FTI. A party seeking to assert collateral estoppel must establish that: (1) the facts sought to be litigated in the second action were fully and fairly litigated in the first action; (2) those facts were essential to the judgment in the first action; and (3) the parties were cast as adversaries in the first action.
Sysco Food Serv., Inc. v. Trapnell,
. Without providing any supporting citation to the record, the Coronados contend Steak-ley personally observed Cenobio and Flores begin repair efforts on the cull tank. In our review of the record, we found no evidence to support this assertion.
