The issue before this court is whether an employee has quit her work without just cause within the meaning of R.C. 4141.29 (D)(2)(a) when that employee voluntarily resigns due to health problems although the employee is physically capable of pursuing and maintaining other available full-time employment with her employer and fails to do so.

R.C. 4141.29(D)(2)(a) establishes the necessary criteria to obtain unemployment compensation benefits for- those who leave their jobs. In pertinent part it provides:

“(D) * * * [N]o individual may serve a waiting period or be paid benefits * * *:

“(2) For the duration of his unemployment if the administrator finds that:

[*17] “(a) He quit his work without just cause or has been discharged for just cause in connection with his work * * *.”

The claimant has the burden of proving her entitlement to unemployment compensation benefits under this statutory provision, including the existence of just cause for quitting work. Shannon v. Bur. of Unemp. Comp. (1951), 155 Ohio St. 53 [44 O.O. 75]; Canton Malleable Iron Co. v. Green (1944), 75 Ohio App. 526 [31 O.O. 304]; 54 Ohio Jurisprudence 2d (1962), Unemployment Compensation, Section 35.

The term “just cause” has not been clearly defined in our case law. We are in agreement with one of our appellate courts that “[t]here is, of course, not a slide-rule definition of just cause. Essentially, each case must be considered upon its particular merits. Traditionally, just cause, in the statutory sense, is that which, to an ordinarily intelligent person, is a justifiable reason for doing or not doing a particular act.” Peyton v. Sun T.V. (1975), 44 Ohio App. 2d 10, 12 [73 O.O.2d 8],

The determination of what constitutes just cause must be analyzed in conjunction with the legislative purpose underlying the Unemployment Compensation Act. Essentially, the Act’s purpose is “to enable unfortunate employees, who become and remain involuntarily unemployed by adverse business and industrial conditions, to subsist on a reasonably decent level and is in keeping with the humanitarian and enlightened concepts of this modern day.” (Emphasis sic.) Leach v. Republic Steel Corp. (1964), 176 Ohio St. 221, 223 [27 O.O.2d 122]; accord Nunamaker v. United States Steel Corp. (1965), 2 Ohio St. 2d 55, 57 [31 O.O.2d 47]. Likewise, “[t]he act was intended to provide financial assistance to an individual who had worked, was able and willing to work, but was temporarily without employment through no fault or agreement of his own.” Salzl v. Gibson Greeting Cards (1980), 61 Ohio St. 2d 35, 39 [15 O.O.3d 49].

We are in basic agreement with the court of appeals below that, in determining “just cause” as that term is construed by Peyton and Salzl, supra, the source or cause of the physical inability to work may be of no import, “at least in the absence of evidence of the employee’s culpability in sustaining or incurring the condition.”^[1] We do not agree, however, with that court’s finding that claimant had just cause for quitting her work, thereby entitling her to unemployment compensation benefits.

The determination of whether just cause exists necessarily depends upon the unique factual considerations of the particular case. Determination of purely factual questions is primarily within the province of the referee and the board. Upon appeal, a court of law may reverse such decisions only if they are unlawful, unreasonable, or against the manifest[*18] weight of the evidence. Brown-Brockmeyer Co. v. Roach (1947), 148 Ohio St. 511, 518 [36 O.O.167]. Like other courts serving in an appellate capacity, we sit on a court with limited power of review. Such courts are not permitted to make factual findings or to determine the credibility of witnesses. Hall v. American Brake Shoe Co. (1968), 13 Ohio St. 2d 11, 13 [42 O.O.2d 6]. The duty or authority of the courts is to determine whether the decision of the board is supported by the evidence in the record. Kilgore v. Bd. of Review (1965), 2 Ohio App. 2d 69, 71 [31 O.O.2d 108]. The fact that reasonable minds might reach different conclusions is not a basis for the reversal of the board’s decision. Craig v. Bur. of Unemp. Comp. (1948), 83 Ohio App. 247, 260 [38 O.O. 356]. Moreover, “[o]ur statutes on appeals from such decisions [of the board] are so designed and worded as to leave undisturbed the board’s decisions on close questions. Where the board might reasonably decide either way, the courts have no authority to upset the board’s decision.” Charles Livingston & Sons, Inc. v. Constance (1961), 115 Ohio App. 437, 438 [21 O.O.2d 65].

In the instant case, our review of the record supports the decision of the board denying claimant unemployment compensation benefits. We agree with the court of appeals below that claimant terminated her employment with N.E.O.D.C on the advice of Drs. Crano and Narraway, and that claimant apprised N.E.O.D.C. of her medical condition and physical limitations. We do not agree with the court of appeals’ finding that claimant attempted to work with N.E.O.D.C. to obtain a less demanding position or that claimant gave N.E.O.D.C. sufficient timely notice to afford it the opportunity of finding satisfactory alternative employment for her. In fact, the record indicates that the exact opposite is true. The referee expressly stated, in his decision, that:

“Claimant took the two doctors’ releases to N.E.O.D.C. and immediately resigned her employment. There was no conversation between claimant and the employer with respect to whether there were any jobs available within the facility which claimant could perform within the medical restrictions. There may have been some work available for the claimant at the Center, but the employer was not given the opportunity to look into the matter.

<<* * *

“* * * The facts presented above indicate claimant quit her employment without inquiring as to whether any other jobs were available which could conform to her medical restrictions.”

In light of the foregoing facts, we do not believe that claimant has carried her burden of establishing just cause for her resignation. Claimant was not “involuntarily” unemployed as required by Leach v. Republic Steel Corp., supra, and Nunamaker v. United States Steel Corp., supra. Nor did claimant satisfy the test we articulated in Salzl v. Gibson Greeting Cards, supra, at 39, that in order to recover unemployment compensation benefits, an employee must be “* * * able and willing to work, but was[*19] temporarily without employment through no fault or agreement of his own.” Claimant was able to work, but was not willing to do so. She was unemployed because she chose to resign her position with N.E.O.D.C. Claimant’s medical condition, which permitted full-time work, and her resultant resignation from N.E.O.D.C., did not justify her failure to pursue alternative employment with N.E.O.D.C. Nor did claimant prove that such alternative positions existed, but were not offered by her employer.

We conclude that the foregoing findings of fact, as determined by the Bureau of Employment Services and the board, and as approved by the trial court below, are not unlawful, unreasonable, or against the manifest weight of the evidence. Claimant therefore is not entitled to unemployment compensation benefits. In sum, we hold that an employee’s voluntary resignation on the basis of health problems is without just cause within the meaning of R.C. 4141.29(D)(2)(a) when the employee is physically capable of maintaining a position of employment with the employer, but fails to carry her burden of proving that she inquired of her employer whether employment opportunities were available which conformed to her physical capabilities and same were not offered to her by the employer.

Judgment reversed.
