USAir, Inc. (employer) appeals a decision of the Workers’ Compensation Commission reinstating benefits to Robert S. Joyce (claimant). Employer contends on appeal that claimant’s failure adequately to market his residual work capacity, as required by Code § 65.2-510, bars his receipt of benefits. For the reasons that follow, we hold that claimant had no duty to market his residual capacity under the facts of this case, and we affirm the commission’s decision.
Claimant, a forty-two-year-old aircraft mechanic, suffered a compensable back injury by accident on September 30, 1992. Claimant received temporary total disability benefits which were suspended on April 27, 1994, based upon a finding that he refused medical treatment by treating with an unauthorized physician. On March 4, 1996, claimant saw Dr. Samuel Hawken, a physician selected from employer’s designated panel. Dr. Hawken released claimant to light-duty work. Claimant subsequently filed a change-in-condition application for reinstatement of his benefits because he had cured his earlier refusal of medical treatment. Employer contested the reinstatement, arguing that claimant failed to market his residual work capacity.
*187The evidence established that after Dr. Hawken released claimant to return to light-duty work, claimant requested work within his capacity from his supervisor, Mr. Zee, and Ted Goodlander, employer’s regional director. They advised claimant that no light-duty work was available. Claimant works for employer under a union contract which precludes his taking outside employment. As a consequence of this contractual limitation, claimant requested a “stipulation” from employer that he be allowed to market outside the company as a real estate agent without losing his job. Employer refused the request, and claimant made no further attempts to market his residual work capacity.
On January 31, 1997, the commission found that claimant had cured his earlier refusal and, under the facts of this case, had adequately marketed his residual capacity.
Dr. Hawkin [sic] released the claimant to light duty. He asked the employer whether he could return to work in a light duty job, and was informed that none was available at that time. He further asked the employer if he had permission to work elsewhere, as a real estate agent, and he was told that he could not do so. As the claimant explained, his contract of employment with USAir prohibits him from accepting employment elsewhere while on disability leave without the employer’s authorization.

[Claimant has reasonably marketed under the circumstances. He offered to return to his pre-injuiy employer in a light duty capacity, but a selective employment position was not available at that time. He then sought authorization to obtain other employment while still remaining an employee and thus maintain eligibility for light duty.... As a matter of equity, the employer cannot have it both ways — on the one hand refusing to allow the claimant to market his capacity, and then denying compensation on the grounds that he has not marketed....
We find that the claimant acted reasonably and prudently in preserving his employment options with USAir, and *188seeking selective work with the company with whom he has a seventeen year employment history, rather than to go against the employer’s dictates.
In order to receive continued benefits under a change-in-condition application, a partially disabled employee must prove that he made reasonable efforts to market his residual wage-earning capacity. See, e.g., Virginia Int’l Terminals v. Moore, 22 Va.App. 396, 401, 470 S.E.2d 574, 577 (1996) (citing National Linen Serv. v. McGuinn, 8 Va.App. 267, 269, 380 S.E.2d 31, 34 (1989)), aff'd, 254 Va. 46, 486 S.E.2d 528 (1997). “Upon judicial review of the commission’s finding that a claimant has made a reasonable marketing effort, the Court must view the evidence in the light most favorable to the prevailing party.” Greif Cos. v. Sipe, 16 Va.App. 709, 716, 434 S.E.2d 314, 318 (1993). However, “[wjhere, as here, there is no conflict in the evidence, ‘the question of the sufficiency of the evidence is one of law.’ ” CLC Constr. Inc. v. Lopez, 20 Va.App. 258, 267, 456 S.E.2d 155, 159 (1995) (quoting National Linen Serv., 8 Va.App. at 270, 380 S.E.2d at 33). “What constitutes a reasonable marketing effort depends on the facts and circumstances of each case.” Sipe, 16 Va.App. at 715, 434 S.E.2d at 318.
Employer contends that claimant failed to prove he reasonably marketed his residual capacity. We disagree. Simply put, employer, by virtue of its employment contract with claimant, offered him an unacceptable choice: to forego workers’ compensation benefits or lose his job. Employer sought to prevent claimant from obtaining the benefits intended by the legislature under the Workers’ Compensation Act by refusing to waive its right to terminate claimant’s employment if he accepted residual employment and then seeking to terminate his disability benefits because he did not seek such employment. We do not believe this result was intended by the legislature.
Our law requires a partially disabled employee to make reasonable efforts to market his residual wage-earning capacity in order to establish entitlement to disability compensation, *189see, e.g., National Linen Serv., 8 Va.App. at 269, 380 S.E.2d at 33, but that law may not fairly be applied to the facts of this case.
The purpose of the Workers’ Compensation Act is to provide compensation to an employee for the loss of his opportunity to engage in work, when his disability is occasioned by an injury suffered from an accident arising out of and in the course of his employment. The Act should be liberally construed in harmony with its humane purpose.
Barnett v. D.L. Bromwell, Inc., 6 Va.App. 30, 33-34, 366 S.E.2d 271, 272 (1988) (en banc) (citation omitted).
Here, the uncontradicted evidence proved that a provision of claimant’s union contract with employer barred him from seeking outside work for the duration of his employment and that he would be fired if he obtained other employment. During a period of partial disability when employer did not offer claimant light-duty work, he requested a “stipulation” or waiver of the provision banning other employment in order to seek work as a real estate agent. Employer refused that request. Employer now seeks to use claimant’s attempt to preserve his employment status, and his concomitant failure to market his residual capacity, to bar his claim for temporary total disability compensation. We hold, in keeping with the decision of the commission, that “[a]s a matter of equity, the employer cannot have it both ways — on the one hand refusing to allow the claimant to market his [residual] capacity [while maintaining his employment status], and then denying compensation on the grounds that he has not marketed.”1
*190For these reasons, we hold that, where the employer has a contractual provision which bars a claimant from working in outside employment while he remains in that employ, and refuses to waive that provision during a period of work-related disability without providing a legitimate business reason for that refusal, claimant has no residual capacity and employer may not assert a “failure to market” defense.
Affirmed.
. As support for its argument that benefits should have been denied, the dissent cites prior decisions of the commission. See Nowlin v. Westvaco Corp., Nos. 170-74—58, 170-74-59 (Workers' Comp. Comm’n Feb. 13, 1996); Hall v. C.R. Hudgins Plating, Inc., 70 O.I.C. 237 (1991); Reynolds v. Gust K. Newberg Constr. Co., 70 O.I.C. 236 (1991); Diehl v. Reynolds Metals Co., 67 O.I.C. 188, 191 (1988); Witt v. Kenrose Mfg. Co., 55 O.I.C. 381 (1973). However, as set out above, no conflict in the evidence exists in this case, making the dispute legal rather than factual. Although "the [cjommission’s construction of the Act is entitled to great weight on appeal,” City of Waynesboro Sheriffs Dep’t v. Harter, 1 Va.App. 265, 269, 337 S.E.2d 901, 903 (1985), this Court is *190not bound by the commission’s legal analysis in this or prior cases. See Cibula v. Allied Fibers & Plastics, 14 Va.App. 319, 324, 416 S.E.2d 708, 711 (1992), aff'd, 245 Va. 337, 428 S.E.2d 905 (1993).
In addition, even if the prior decisions of the commission were legally binding upon this Court, the commission’s award of benefits in this case indicates its belief that those decisions are factually distinguishable. We agree.
First, the commission’s language in Diehl is dictum because it found the claimant in that case had an ongoing total disability and had no residual capacity to market at that time.
Second, Hall dealt only with the principle that an employee hoping to be recalled to light duty with her pre-injury employer has a duty to market her residual capacity in the interim. It did not indicate that Hall’s marketing would have caused her to forfeit employment status with employer and the possible future return to a light-duty position with employer.
Finally, the Nowlin, Reynolds and Witt cases, as stated in the text of those opinions, all dealt exclusively with benefits resulting from union membership and their possible forfeiture upon a claimant’s acceptance of other employment. Like Hall, none of those decisions indicate that the employer had control over the claimant’s loss of employment or possible forfeiture of benefits. It is undisputed on the record in the instant case that USAir had such control. Furthermore, the commission found that, because "employment contracts in Virginia cover both union and non-union employees, ... the claimant’s union membership is irrelevant to the issue of his right to compensation.”
