The employer, Colonial Acres Nursing Home, and its insurance carrier, St. Paul Fire & Marine Insurance Company, appeal from a pro forma decree entered by the Superior Court, Kennebec County, which upheld a decision of the Workers’ Compensation Commission awarding the worker, Charlotte Mailman, compensation for partial incapacity. The appellants argue that the Commission erred in awarding benefits because there was no evidence of a causal connection between the worker’s disability and her inability to find employment, there was insufficient medical evidence establishing a causal nexus between the worker’s present disability and her original injury and the Commission improperly failed to reduce the award by the amount of unemployment benefits received by the worker. We affirm the judgment.
On May 1, 1976, Mailman suffered a com-pensable back injury while employed as a kitchen worker and cleaning woman at the appellant’s nursing home in Lincoln. Under an approved agreement, she received compensation for total incapacity until November 28,1976, when she began work as a winding machine operator at a textile mill in the same town. Although Mailman maintained that she experienced physical discomfort in her back and needed assistance in performing this work, she continued in a full-time job at the mill until the end of September, 1978, when the mill laid off its employees because supply problems caused a temporary shutdown of operations. From mid-October, 1978, until April, 1979, Mailman received unemployment compensation, and not until June, 1979, did she begin what proved to be an unsuccessful search for employment.
In February, 1979, the worker filed a petition for further compensation. The only physician produced at the hearing on this petition testified that Mailman currently suffers from osteoarthritis in the lower lumbar spine region and that this disability precludes moderate to heavy work activity. This physician also testified that Mailman’s current disability, although degenerative in origin, had been aggravated by the industrial injury. The Commission found that the worker is partially disabled as a result of the 1976 injury and ordered that she receive compensation for partial incapacity as of October 1, 1978.
Before we consider the appellants’ three claims of error, we must first determine whether we have jurisdiction to hear this appeal.
See, e. g., Wood v. Wood,
Me.,
Whenever a judgment of the Superior Court ... is by law reviewable by the Law Court, such review shall be by appeal in accordance with these rules.... The time within which an appeal may be taken shall be 30 days from the entry of the judgment appealed from unless a shorter time is provided by law, except that: (1) upon a showing of excusable neglect the court in any action may extend the time for filing the notice of appeal not exceeding 30 days from the expiration of the original time herein pre *220 scribed; .... M.R.Civ.P. 73(a) (emphasis added).
Because this rule clearly authorized the Superior Court, upon a finding of excusable neglect, to grant the extension in the instant case, we have jurisdiction over the appeal, notwithstanding that the notice was untimely under 39 M.R.S.A. § 103.
The appellants first challenge the Commission’s determination of partial incapacity, arguing that as a matter of law an injured worker who has returned to work is entitled to compensation when he is laid off from that job only if he can show by competent evidence a causal connection between an inability to find employment and his disability.
See Rugan
v.
Dole Co.,
Me.,
The record in the instant case discloses competent evidence that, unlike that of the workers in
Rugan
and
Coty,
Mailman’s post-injury employment at the textile mill did not reflect an undiminished work capacity.

See Midland
—Ross
Corp. v. Industrial Commission,
The appellants also contend that the worker failed to establish the requisite causal connection between the industrial injury and her present disability,
see, e. g., MacLeod v. Great Northern Paper Co.,
Me.,
Finally, the appellants assert that the Commission erred in failing to decrease the award by the amount of the unemployment benefits the worker received from mid-October, 1978, until April, 1979. With exceptions not here relevant, 39 M.R.S.A. § 62-A directs the Commission to reduce compensation by the amount of any unemployment benefits received by the worker during the period of the award.

Id.
This enactment, P.L.1979, ch. 496, § 2, became effective in September of 1979 and radically changed prior decisions of this Court which held that the Commission lacked authority to set off amounts received in the form of unemployment benefits.
E. g., Murray v. City of Augusta,
Me.,
This argument is without merit. Unlike the purely procedural provisions at issue in
Sutherland
and
Batchelder,
Section 62-A vitiated the right of Maine workers to compensation awards that were undiminished by any unemployment benefits they might also have received. As a direct legislative response to contrary case law, the statute declares new public policy, altering the rights of injured workers under the compensation scheme.
Cf. Langley v. Home Indemnity Co.,
Me.,
The entry is:
Judgment affirmed.
It is further ordered that the appellants pay to the appellee an allowance of $550.00 for her counsel fees plus her reasonable out-of-pocket expenses for this appeal.
All concurring.
Notes
. Although a worker’s post injury earnings are good evidence of the effect of the injury on his capacity to earn, they do not conclusively establish the worker’s earning capacity. See generally 2 A. Larson, The Law of Workmen’s Compensation § 57.31 (1976).
. Because it found that Mailman had not made reasonable efforts to secure employment within her physical limitations, the Commission refused to award her compensation for total inca-pacify.
See, e. g., Crocker v. Eastland Woolen Mill, Inc.,
Me.,
.In support of their contention regarding the necessity of medical evidence on the issue of causation, the appellants rely on two per cu-riam decisions both of which are inapposite. In
Gardner v. D. W. Small & Sons,
Me.,
. Section 62-A provides in pertinent part:
Compensation paid under this Act, ... to any employee for any period with respect to which he is receiving or has received benefits under the employment security law, shall be reduced by the amount of the unemployment benefits. 39 M.R.S.A. § 62-A(1).
