At issue is whether plaintiff, Claude Oxley, allegedly injured in the course of his work as a National Guard technician, was a covered employee for purposes of the Worker’s Disability Compensation Act (WDCA), MCL 418.101 et seq.; MSA 17.237(101) et seq. We conclude that Oxley, in his capacity as a civilian technician, was not in the service of the state and *538is therefore ineligible for benefits under MCL 418.161(l)(a); MSA 17.237(161)(l)(a) of the wdca. We accordingly reverse the judgment of the Court of Appeals and reinstate the decision of the Worker’s Compensation Appellate Commission (WCAC), which affirmed the magistrate’s ruling.
FACTS AND PROCEEDINGS
Oxley’s full-time job during the period at issue was as a National Guard technician. Since 1969, such technicians have been classified as federal employees under 32 USC 709(d). This position required that he be a member of the Michigan Air National Guard. See 32 USC 709(b)(1). As a member of the Michigan Air National Guard, Oxley served one weekend a month plus fifteen days of summer camp each year.
Oxley’s technician position involved computer operations. He had received four weeks of training, but felt that he was insufficiently trained and supported in his job. He alleged that the resulting stress caused him to suffer a myocardial infarction on November 13, 1985. While he returned to work after the heart attack, Oxley contended that his return to the same job subjected him to the same stress and resulted in further disability.1 He was terminated from military service because of medical disqualification on October 17, 1986, and terminated from his federal civil service status on February 27, 1987. He receives federal pension benefits.
On September 27, 1990, Oxley sought Michigan worker’s compensation benefits, alleging continuing *539disability due to work-related injuries. However, Oxley did not seek federal worker’s compensation benefits for the injuries at issue.2
The magistrate denied Oxley’s claim for worker’s compensation benefits, ruling that he was not an employee covered under Michigan’s wdca. She concluded that Oxley was a federal employee for purposes of the WDCA. In reaching this conclusion, she relied on 32 USC 709, which states that a technician is a federal employee. She noted that Oxley received his pay and annual W-2s from the federal government and that his sick and vacation time and other benefits were provided through the federal civil service system. She also found, significantly, that the state adjutant general, Oxley’s supervisor, is a federal employee for purposes of administering technicians.
The wcac affirmed the magistrate’s analysis and conclusion. 1996 Mich ACO 675. Additionally, it acknowledged Tulppo v Ontonagon Co, 207 Mich App 277; 523 NW2d 883 (1994), which indicated that wages earned for service in the National Guard should be included in the computation of weekly wage-loss benefits under the wdca when a claimant is injured in the course of concurrent employment that is covered under the WDCA. However, on the basis of limiting language in Tulppo, the wcac concluded that Oxley was limited to the worker’s compensation benefits available under the Federal Employees’ Compensation Act.
The Court of Appeals granted leave and reversed. 227 Mich App 528; 575 NW2d 820 (1998). It con-*540eluded that Oxley was both a federal and a state employee and was therefore eligible for worker’s compensation benefits under Michigan’s WDCA. It relied on federal authority indicating that 32 USC 709 made technicians “nominal” federal employees for the limited purpose of making them eligible for federal fringe and retirement benefits and for coverage under the Federal Tort Claims Act. It rejected defendant’s contention that technicians like Oxley wear two hats — they are civilian federal employees while acting as technicians, but members of the military, arguably employed by the state, while engaging in National Guard duties, i.e., when in military training or actual military service. Rather, the Court of Appeals held that Oxley’s work as a technician was military in character and required that he be a member of the National Guard. Applying the economic reality test, it concluded that Oxley was employed by the state because he was voluntarily in the service of the state and subject to its control and direction in his work. It stated that the limiting language in Tulppo, relied upon by the WCAC, was dicta. Finally, it noted that Oxley was not receiving federal worker’s compensation benefits and that there was accordingly no danger of double recovery, which was the basis of Tulppo’s limiting language.
This Court granted leave to appeal. 459 Mich 927 (1998).
STANDARD OF REVIEW
Whether Oxley was an employee of the state for purposes of Michigan’s WDCA is a question of law. This Court has the authority to review questions of law involved in any final order of the WCAC. MCL 418.861; *541MSA 17.237(861). This Court reviews questions of law de novo. Hagerman v Gencorp Automotive, 457 Mich 720, 727; 579 NW2d 347 (1998).
DISCUSSION
In order to be eligible for Michigan WDCA benefits, a claimant must be a “covered” employee. Oxley contends that he was a covered employee because he was in the service of the state pursuant to MCL 418.161(l)(a); MSA 17.237(161)(l)(a).3
Before beginning to analyze whether Oxley was a covered employee under § 161(l)(a),4 it is helpful to frame the issue by reiterating some facts that are undisputed.
Oxley’s allegations in his petition for worker’s compensation benefits acknowledge that the injuries at issue arose in the course of his civilian technician work, i.e., his forty hour a week job; not in the course of his military National Guard service, i.e., his service one weekend a month and fifteen days of summer *542camp each year. Further, both parties agree that, pursuant to 32 USC 709, technicians are federal employees and are under the authority of the state adjutant general.5 It is undisputed that Oxley’s wages were paid by federal funds on a federal paycheck and that his sick and vacation time and other benefits were provided through the federal civil service system. Further, defendant concedes that Oxley was a state employee with respect to his military National Guard duties.
*541As used in this act, “employee” means:
(a) A person in the service of the state . . . under any appointment, or contract of hire, express or implied, oral or written.
*542Given these facts, the issue is whether Oxley was exclusively a federal employee or simultaneously a federal employee and a state employee when the injuries at issue arose. It is agreed that if these injuries arose in the course of work as to which he was exclusively a federal employee, Oxley would not be a covered employee under § 161(l)(a) and thus would be ineligible for Michigan wdca benefits. However, if they arose in the course of work as to which he was both a federal and a state employee, he would be eligible to pursue Michigan wdca benefits under § 161(l)(a).6
*543I
As to whether Oxley’s civilian technician work can be differentiated from his military National Guard service, Oxley argues that the civilian and military aspects of his work cannot be separated and that he was simultaneously a federal employee and a state employee. Defendant, of course, contends that Oxley’s work can be bifurcated into its civilian and military elements. It claims that Oxley was a federal employee in his capacity as a technician and a state employee with respect to his military National Guard service.
The only Michigan case cited by the parties as bearing on this issue is Tulppo, 207 Mich App 277. In Tulppo, a sheriff, who was also a member of the National Guard, sought Michigan worker’s compensation benefits for an injury suffered in the course of his sheriff’s duties. There was no dispute that his sheriff position was clearly covered employment under § 161(l)(a). The only question was if, in setting his worker’s compensation benefits, the plaintiff’s pay for National Guard service should be considered. The Tulppo Court answered in the affirmative, holding that “for the limited purpose of determining average weekly wage loss under § 371 of the wdca, Michigan National Guard members are state employees and . . . fall within the express language of § . . . 161.” Id. at 282. Thus, the Tulppo Court dispositively concluded that where a claimant is injured in the course of covered employment, the claimant’s pay for National Guard service may be considered in calculating worker’s compensation benefits. While it discussed the Legislature’s intent to provide worker’s compensation benefits to National Guard members *544“injured or killed in the course of other concurrent employment covered by the act,” the question whether such other concurrent employment is covered by the act, as is at issue here, simply was not before the Tulppo Court.7 207 Mich App 285. Thus, Tulppo provides no guidance regarding whether a technician position constitutes other concurrent employment that is covered by Michigan’s wdca. Nor does Tulppo shed any light on the specific question whether Oxley’s civilian technician work can be separated from his military National Guard service.
Given the paucity of Michigan authorities addressing the issues we confront, we turn to cases from other jurisdictions for guidance. Some federal cases have indicated a categorical conclusion that the civil and military aspects of a technician position are inseparable. However, even cases taking this approach focus on the fundamentally military elements of the challenges at issue in concluding that technicians’ civilian status could not be unraveled from their military service. For example, in Wright v Park, 5 F3d 586 (CA 1, 1993), the United States Court of Appeals for the First Circuit affirmed a summary judgment dismissing a technician’s claim that his job transfer was retaliation for whistle-blowing. Because a member of the military cannot pursue such a claim, *545the plaintiffs ability to proceed turned on whether his civilian work could be separated from his military service. The Wright court rejected the plaintiffs proposed “Balkanization of technicians’ work” into separate military and civilian elements because it concluded that “the adverse employment action against which appellant inveighs necessarily implicates his military as well as his civilian status.” Id. at 588-589. American Federation of Government Employees, AFL-CIO, Local 2953 v Federal Labor Relations Authority, 235 US App DC 104; 730 F2d 1534 (1984), held that the National Guard was not required to bargain over a union proposal to eliminate consideration of military performance from reduction-in-force actions regarding technicians. In so holding, the court noted that the National Guard Bureau regulation requiring consideration of both civilian and military performance has repercussions on military preparedness. Id. at 111, 116. See also New Jersey Air Nat’l Guard v Federal Labor Relations Authority, 677 F2d 276 (CA 3, 1982) (holding that the National Guard was not required to bargain over certain conditions of employment with a union representing civilian technicians).
More recent federal cases explicitly hold that the military and civilian aspects of a technician’s position can be separated with respect to claims that do not implicate integrally military elements of such positions. In two recent decisions, the United States Court of Appeals for the Ninth Circuit held that title vn of the federal civil rights act applied to National Guard technicians except with respect to personnel decisions “integrally related to the military’s unique structure.” Mier v Owens, 57 F3d 747, 748 (CA 9, *5461995); Gregory v Widnall, 153 F3d 1071, 1074 (CA 9, 1998). The Mier court noted that title vn’s protection against employment discrimination applies to civilian employees of the military, but not to military personnel. Mier at 749. In order for a technician to be eligible to pursue claims available to civilian employees but not military personnel, it is necessary to bifurcate the technician’s civilian work from his military service. Accordingly, Gregory and Mier indicate that, unless the situation under scrutiny is fundamentally military, the civilian aspect of National Guard technician positions may be differentiated from the military aspect and considered separately.
Careful examination of the facts in these cases provides guidance in identifying when the military and civilian aspects of a technician position cannot be separated. In Mier, a technician alleged discrimination and retaliation in 1) the denial of military promotions, 2) suspension from civilian employment resulting from the military promotion denials, and 3) subjection to an investigation. At issue was whether the plaintiff could utilize uniquely civilian remedies, unavailable to military personnel, such as a suit under title vn of the federal civil rights act. The Mier court concluded that he could not. It stated that “[military promotion is one of the most obvious examples of a personnel action that is integrally related to the military’s structure” and accordingly held that the denial of a military promotion and a resulting suspension from civilian employment were integrally military issues that are not reviewable under title vn. Id. at 751. It also concluded that investigations are “central to the military’s unique concerns regarding discipline and control” and accordingly are not reviewable *547under title vn. Id. Similarly, the Gregory court rejected a technician’s attempt to pursue a title vn action because it found that his allegations relating to a military promotion were “integrally related to the military’s unique structure.”8 153 F3d 1074.
These cases all indicate that the judicial inquiry is to determine if bifurcation is possible or if the civilian and military aspects of the employment are so commingled that an unraveling is impossible. The bottom line is that, except with respect to claims implicating integrally military issues, technician work can be separated into its civilian and military elements.
The issue here is Oxley’s eligibility for state worker’s compensation benefits regarding injuries allegedly incurred in the course of civilian work as a technician. This issue does not affect any issue integrally related to the military’s unique structure, nor does plaintiff claim that it does. This is reasonable because the availability of state worker’s compensation benefits does not implicate fundamentally military issues such as military discipline, military promotions or the nation’s military preparedness. Therefore, the present case is distinct from the cases discussed above in which the claim affected on such fundamentally military issues, making it impossible to separate the technicians’ civilian work from their military service. Accordingly, the civilian and military aspects of Oxley’s position may be treated separately here for purposes of determining his eligibility for Michigan *548worker’s compensation benefits for injuries arising in the course of civilian technician work.
In the context of a claim for worker’s compensation benefits, the next issue is whose service the claimant was in when the alleged injuries arose. Here, this issue is simple because Oxley himself acknowledges that the injuries at issue arose in the course of his civilian technician work.9 32 USC 709(d) explicitly states that Oxley is a federal employee in his capacity as a technician.10 The arguable basis for considering him simultaneously in the service of the state was his military service with the National Guard. However, because his civilian technician status can be separated from his military service with respect to eligibility for state worker’s compensation benefits, Oxley’s injuries did not arise in the course of employment in the service of the state. Accordingly, he is not a covered employee under § 161(l)(a).
*549n
However, before closing the door on Oxley’s claim, we must address a final issue raised by the Court of Appeals conclusion that, even in his capacity as a technician, Oxley was employed by the state under the economic reality test. 227 Mich App 534. This test is well set out in the recent case of Kidder v Miller-Davis Co, 455 Mich 25, 34; 564 NW2d 872 (1997), where this Court reiterated that it had rejected the control test in favor of the economic reality test to determine who is an employer for purposes of the WDCA. Specifically, the Kidder Court held:
[T]his standard examines a number of criteria including [1] control, [2] payment of wages, [3] hiring, firing, [and] the maintenance of discipline, and [4] common objective. These factors are viewed together in their entirety under a totality of the circumstances test. [Id. at 42.]
On the basis of this test, Oxley claims state employee status. He contends that because the adjutant general, an agent of the state, controlled him and had authority to hire, fire, and discipline him, he was an employee of the state. In making this argument, Oxley relies on 32 USC 709(c), which authorizes the state adjutant general to supervise technicians. Overlooked in his analysis, however, is the fact that federal cases establish that in the capacity where they administer technicians, state adjutants general act as federal agents, not state agents.
In Gilliam v Miller, 973 F2d 760, 762 (CA 9, 1992), the Ninth Circuit held that an adjutant general’s “personnel actions as supervisor over the federal civilian technicians are taken in the capacity of a federal agency,” but his actions in supervising the state *550National Guard are in the capacity of a state agency. Similarly, in Leistiko v Stone, 134 F3d 817, 818 (CA 6, 1998), a wrongful discharge case, the Sixth Circuit stated that the adjutant general acted as “the designee of the Secretary of the Army” in terminating a technician’s employment after he was removed from flying status for medical reasons.
Thus, as these authorities persuasively advance, Oxley cannot utilize the status of his supervisor to advance his claim that the economic realities indicate that he was a state employee because his contention that the adjutant general was acting as a state agent in supervising his civilian technician work is untenable. This disposes of factors 1 (control) and 3 (hiring, firing, and discipline authority) of the economic reality test.
The other two factors also militate toward a conclusion that Oxley was a federal employee, not a state employee, in his civilian technician work. Regarding factor 2 (wages), it is undisputed that Oxley received his wages by a federal paycheck and from federal funds. Further, his sick and vacation time and other benefits were provided under the federal civil service system. Finally, with respect to factor 4 (common objective), Oxley’s work as a technician was part of the common objective of the federal government to provide for the common defense. See US Const, preamble, art I, § 8. Therefore, these remaining factors of the economic reality test also demonstrate that Oxley was not a state employee in his capacity as a technician.
Accordingly, under both the statutory language and the economic reality test, Oxley, in his capacity as a technician, was not in the service of the state of *551Michigan. Therefore, this employment was not covered under § 161(l)(a) and he is not eligible to pursue benefits under Michigan’s wdca for an injury allegedly suffered in the course of his civilian technician work.
CONCLUSION
For these reasons, we conclude that, in his capacity as a civilian technician, Oxley was not a covered employee under § 161(l)(a) of the wdca. We accordingly reverse the judgment of the Court of Appeals and reinstate the decision of the Worker’s Compensation Appellate Commission, which affirmed the magistrate’s decision.
