Does the Workers’ Compensation Act permit termination of benefits where a claimant is capable of performing his pre-injury job without restrictions despite minor residual physical effects from the injury? May benefits be terminated or suspended where, following the employer’s cessation of business, such a claimant begins working for a different employer, performing the same duties as his pre-injury job, at a lower wage? These are the questions raised in this appeal.
John W. Harle was employed as a pressman with Telegraph Press, Inc. While working on October 12, 1987, he cut and fractured his left thumb. As a result, he received total disability payments of $359.40 per week based on an average weekly wage of $539.10, pursuant to a notice of compensation payable.
Harle’s treating physician released him to return to light duty work on March 28, 1988. He released him to full duty with no restrictions on April 22, 1988. Telegraph Press, however, had ceased conducting business in February of that same year. In August of 1988, a termination petition was filed [484]*484on behalf of Telegraph Press and’ its insurance carrier, asserting that Harle’s disability had ceased.
In deposition testimony taken in May and June of 1989, Harle’s physician testified that he had seen Harle in March of that year. Although Harle complained about discomfort and stiffness in his left hand and wrist, examination showed a full range of motion at the wrist and where the thumb joins the hand, and good though slightly reduced range at the thumb joint where the injury had occurred. The doctor expressed his opinion that Harle should be able to perform the duties described to him as being incident to employment as a pressman.
At a hearing in July of 1989, Harle testified that he continued to experience pain in his wrist when performing heavy duties, and had problems grasping some tools. He acknowledged that he had begun working for Directory Printing Company in September of 1988, was laid off from January 30 through May 5, 1989, and had not lost any working days because of the thumb injury since then. He also indicated that he had worked for two weeks during the layoff period with a printing company of which he is part-owner. Harle testified that his hourly wage at Directory Printing was $11.50, roughly $2.00 per hour less than his wage at Telegraph Press.
The referee1 found the physician’s testimony to be credible and determined in his conclusions of law that “all claimant’s disability relative to the injury of October 12, 1987 has ceased.” He ordered termination of benefits as of April 22, 1988. The Board affirmed, stating that the substance of the doctor’s testimony was that all work-related disability had ceased, even if he failed to use those “magic words.” Commonwealth Court, however, reversed and remanded for a determination of partial disability benefits.
The court, citing Rogers Motor Lines v. Workmen’s Compensation Appeal Board (Baker), 144 Pa.Commw. 493, 496, [485]*485601 A.2d 934, 935 (1992), stated that “[a] termination petition may only be based upon a properly supported finding ‘that the claimant’s disability has entirely ceased.’ ” (Emphasis in original). Highlighting the doctor’s testimony that Harle continued to have a reduced range of motion in the thumb joint, the court concluded that there was not substantial evidence to support the findings necessary for a termination of benefits.
Commonwealth Court then proceeded to examine whether the employer might be entitled to any form of relief other than termination of benefits. The court stated that where “an employee can return to his pre-injury position, but ... continues to suffer some residual impairment, a suspension of benefits is proper because the medical disability does not manifest itself in a loss of earnings.” 155 Pa.Commw. 556, 562, 625 A.2d 751, 754, citing Hawkins v. Workmen’s Compensation Appeal Board (Medical College of Pennsylvania), 138 Pa.Commw. 180, 587 A.2d 387 (1991). The court further stated that where the pre-injury position is not available, however, “a suspension of benefits is not warranted because the employer has not proven the necessary element of job availability.” 155 Pa.Commw. at 563, 625 A.2d at 754, citing Zimcosky v. Workmen’s Compensation Appeal Board (United States Steel Corp.), 118 Pa.Commw. 209, 544 A.2d 1106 (1988).
The court treated this case as a “hybrid” of these two situations, because although the medical evidence indicated that Harle could return to his pre-injury employment, and although his pre-injury position was no longer available, Harle admitted that he had obtained a similar position elsewhere, albeit at a lower wage. This admission obviated the need for the employer to produce evidence of job availability. Thus the court found that modification of benefits to partial disability was the appropriate remedy, and remanded for calculation of benefits based on the difference between Harle’s pre-injury wages and his current wages.
On appeal to this Court, the employer argues that the Commonwealth Court’s analysis is inconsistent with the longstanding interpretation that the disability that entitles a per[486]*486son to benefits under the Workmen’s Compensation Act is synonymous with “loss of earning power.” See Dillon v. Workmen’s Compensation Appeal Board (Greenwich Collieries), 536 Pa. 490, 640 A.2d 386 (1994); Kachinski v. Workmen’s Compensation Appeal Board (Vepco Construction Company), 516 Pa. 240, 532 A.2d 374 (1987); Unora v. Glen Alden Coal Company, 377 Pa. 7, 104 A.2d 104 (1954). The employer contends that even if there is a “residual physical impairment” or “medical disability,” a claimant should not continue to receive benefits if there is no longer any loss of earning power attributable to the work-related injury. Otherwise, benefits are simply a wage supplement for a worker who by chance is recovering from an injury at the time his employer ceases doing business but later obtains full-time employment, which for reasons unrelated to the injury pays a lower wage. We agree.
The flaw in the Commonwealth Court’s reasoning derives from a misreading of Zimcosky, which in turn was based on our Court’s decision in Kachinski.

This admission obviated the need for the employer to produce evidence of job availability. Thus the court found that modification of benefits to partial disability was the appropriate remedy, and remanded for calculation of benefits based on the difference between Harle’s pre-injury wages and his current wages.
On appeal to this Court, the employer argues that the Commonwealth Court’s analysis is inconsistent with the longstanding interpretation that the disability that entitles a per[486]*486son to benefits under the Workmen’s Compensation Act is synonymous with “loss of earning power.” See Dillon v. Workmen’s Compensation Appeal Board (Greenwich Collieries), 536 Pa. 490, 640 A.2d 386 (1994); Kachinski v. Workmen’s Compensation Appeal Board (Vepco Construction Company), 516 Pa. 240, 532 A.2d 374 (1987); Unora v. Glen Alden Coal Company, 377 Pa. 7, 104 A.2d 104 (1954). The employer contends that even if there is a “residual physical impairment” or “medical disability,” a claimant should not continue to receive benefits if there is no longer any loss of earning power attributable to the work-related injury. Otherwise, benefits are simply a wage supplement for a worker who by chance is recovering from an injury at the time his employer ceases doing business but later obtains full-time employment, which for reasons unrelated to the injury pays a lower wage. We agree.
The flaw in the Commonwealth Court’s reasoning derives from a misreading of Zimcosky, which in turn was based on our Court’s decision in Kachinski. In Kachinski, we assigned to the employer the burden of proving the availability of work within the employee’s physical limitations when the employer seeks modification of benefits. We further clarified that “availability” means “actual availability,” and adopted the Commonwealth Court’s explanation that
a position may be found to be actually available, or within the claimant’s reach, only if it can be performed by the claimant, having regard to his physical restrictions and limitations, his age, his intellectual capacity, his education, his previous work experience, and other relevant considerations, such as his place of residence.
Kachinski v. Workmen’s Compensation Appeal Board (Vepco Construction Company), 91 Pa.Commw. 543, 546, 498 A.2d 36, 38-39 (1985). Our Opinion dealt entirely with what an employer had to prove and whether the employer in that case had introduced sufficient evidence to meet its burden. Other than to indicate generally that modification of benefits would be in order, the Opinion did not discuss the ultimate ramifications of the employer’s meeting its burden. Such issues were not presented in the case.
[487]*487In Zimcosky, the employer “presented absolutely no testimony as to work availability in claimant’s department, at its mill, or at any other job.” 118 Pa.Commw. at 212, 544 A.2d at 1107 (emphasis added.) Moreover, it was apparent from the record that the claimant’s pre-injury job was unavailable due to a departmental closing and a mill-wide layoff. Therefore, despite the medical evidence that the employee was physically capable of working, there was no record evidence of actual work availability. This would have been sufficient reason to deny the suspension of benefits consistent with Kachinski.
Actual work availability, however, is only one of the considerations affecting the modification question. Although the analysis in Kachinski and Zimcosky could stop there because the evidence in those cases was such that the remaining issues did not arise, in the present case those issues are squarely presented. Commonwealth Court neglected to address those issues, noting only that the fact of the claimant’s employment obviated the employer’s burden of proving actual work availability. The court simply assumed that any difference between pre-injury and post-injury earnings constituted the base for determining partial disability benefits, without responding to the employer’s argument that such benefits are only appropriate where the difference is related to the injury.
The provision governing benefits for partial disability is Section 306(b) of the Act, as amended, 77 P.S. § 512. It provides in relevant part
For disability partial in character ... sixty-six and two-thirds per centum of the difference between the wages of the injured employe, as defined in section three hundred and nine [77 P.S. § 582], and the earning power of the employe thereafter.... The term “earning power,” as used in this section, shall in no case be less than the weekly amount which the employe receives after the injury, and in those cases in which the employe works fewer than five days per week for reasons not connected with or arising out of the disability resulting from the injury shall not be less than five times his actual daily wage as fixed by the day, hour, or by the output of the employe....
[488]*488We find it significant that the legislation states that “ ‘earning power’ ... shall in no case be less than the weekly amount which the employe receives after the injury....” (Emphasis added.) The inference suggested by this language is that “earning power” can, in some cases, be more than the employee is receiving in actual wages after the injury. In other words, benefits for partial disability are based on the difference between pre-injury earnings and post-injury earning power, not post-injury earnings, although in no case can the difference be greater than the difference between pre-injury earnings and post-injury earnings.
Pursuant to this reading of the statute, an employee whose earning power is no longer affected by his work-related injury is no longer entitled to partial disability benefits, even though his earnings may not match his pre-injury earnings. This view is supported by the remaining statutory language quoted above, which indicates that where “the employee works fewer than five days per week for reasons not connected with or arising out of the disability resulting from the injury [earning power] shall not be less than five times his actual daily wage.” (Emphasis added.) Thus if a worker is able to secure employment that, not because of limitations caused by the injury but for other reasons, is only part-time, his “earning power” is calculated as though he were employed full-time.
Similarly, Section 413 of the Act, as amended, 77 P.S. § 772, which authorizes modification, reinstatement, suspension, or termination of benefits, contains a proviso
That where compensation has been suspended because the employe’s earnings are equal to or in excess of his wages prior to the injury that payments under the agreement or award may be resumed at any time during the period for which compensation for partial disability is payable, unless it be shown that the loss in earnings does not result from the disability due to injury.
(Emphasis added.)
We note that Section 413, unlike section 306(b), is drafted in terms of the employee’s post-injury earnings being equal to or [489]*489greater than his pre-injury wages, and it being shown that the loss in earnings does not result from the disability due to injury. Despite this discrepancy, we perceive in both sections a legislative intent that benefits for partial disability are payable to remedy loss caused by a work-related injury but are not payable if the loss is due to factors other than such injury.
For the foregoing reasons, we hold that Commonwealth Court committed an error of law in remanding this case for computation of partial disability benefits. The referee’s findings of fact, which were based on substantial evidence, supported his conclusion “that all claimant’s disability relative to the injury of October 12, 1987, has ceased.” Given Harle’s testimony that he was employed full-time and had not lost any work time due to the injury, it can be concluded that any difference between Harle’s pre-injury wages and post-injury earning power was due to factors other than the injury to his thumb.
Commonwealth Court was correct, however, in ruling that termination of compensation was inappropriate. In light of the testimony of the physician, which the referee deemed credible, that Harle continued to experience residual physical impairment from the injury, suspension of benefits is the appropriate remedy. This allows for the possibility that if Harle’s earning power at some time in the future is affected by the residual impairment from the injury, he may seek reinstatement of partial disability benefits by proving only that the injury giving rise to the original claim continues and that his earning power is once again adversely affected by the injury. See Pieper v. Ametek-Thermox Instruments, 526 Pa. 25, 584 A.2d 301 (1990).
To the extent that it remanded for the calculation of partial disability benefits, the Order of the Commonwealth Court is vacated. The matter is remanded to the Board, with instructions that the claimant’s benefits be suspended.
