This case involves a petition, filed pursuant to section 10(e) of the National Labor Relations Act (“NLRA” or “Act”),
1
for enforcement of a remedial order entered by the National Labor Relations Board (“NLRB” or “Board”) against Henry Cauthorne, the proprietor of a small Washington, D.C. trucking firm. We have carefully considered each of Cauthorne’s many challenges to the Decision and Order of the NLRB,
I. Background
The bargaining relationship at issue commenced in 1972, when Cauthorne signed a collective bargaining agreement with the Union, executed Health and Welfare and Pension Fund Trust Agreements, and began making payments into the trust funds on behalf of his employees. Although that initial agreement expired in 1975 and Cauthorne did not sign a new contract, “substantial evidence on the record considered as a whole,” 3 — including Cauthorne’s continued and faithful adherence to the trust agreements — supports the Board’s conclusion that he was bound by the 1975-1978 contract between the Construction Contractors Council, Inc. and the Union.
Shortly before the expiration date of the 1975-1978 contract, Union representatives approached Cauthorne to discuss a new agreement. Cauthorne initially indicated that he would not sign another contract, but then met with Union officials on several occasions. These meetings were apparently unproductive, for Cauthorne never signed a new contract, and he terminated his trust fund contributions when the 1975-1978 contract expired on July 31,1978. Between July 1978 and January 1979: Cauthorne conferred by telephone at least once with the Union’s president; the Union filed a section 8(a)(5) refusal to bargain charge that was subsequently dismissed; and the parties exchanged several exploratory letters. These contacts finally culminated in a meeting between a Union business agent and Cauthorne’s attorney on January 30, 1979. The participants’ accounts of this negotiation session diverge sharply, but their testimony makes clear that continued negotiations were unlikely to shrink the gap between the parties’ positions. Transcript of Proceedings before NLRB (“Tr.”) 213, 222-23.
During the post-January 30,1979 communications between the parties, the Union’s representative initiated a series of letters by demanding the addresses of Cauthorne’s employees, requesting a counterproposal, and asserting that “we will not serve any useful purpose by prolonging our negotiations.” Respondent’s Exhibit (“R.E.”) 14. In response to Cauthorne’s request for “a new proposal to break the impasse,” R.E. 15, the Union sent a copy of its original proposal, R.E. 16; Tr. 214 — 16. Cauthorne’s attorney then provided the Union with a mailing list, R.E. 18, and, on May 10,1979, a counterproposal, R.E. 19, but never received any response from the Union, Tr. 214.
II. Discussion
Without considering whether the parties had reached an impasse in the communications that followed the January 1979 meeting, the NLRB ordered Cauthorne to pay “all health and welfare trust fund contributions, as provided in the expired collective-bargaining agreement, ... until . .. [he]

negotiates in good faith to a new agreement or to an impasse.”
A. Introduction: The General Prohibition Against Unilateral Changes in Conditions of Employment
Under the NLRA, it is clear that an expired collective bargaining agreement continues to define the status quo as to wages and working conditions, and that “[t]he employer is required to maintain that status quo ... until the parties negotiate to a new agreement or bargain in good faith to impasse.”
NLRB v. Carilli,
B. The Appropriate Remedy In a Case Involving a Unilateral Change Followed By a Bargaining “Impasse”
In cases involving a violation of section 8(a)(5) based on an employer’s unilateral alteration of existing benefits,
it is the Board’s established policy to order restoration of the status quo ante to the extent feasible, and in the absence of evidence showing that to do so would impose, an undue or unfair burden upon the respondent.

Allied Products
arguably can be read to suggest that an employer who has instituted a unilateral change in his employees’ wages or working conditions cannot cure his violation by subsequently bargaining to an impasse.
See id.; NLRB v. Allied Products Corp., Richard Brothers Division,
In designing a remedy in a section 8(a)(5) case, a crucial variable is the duration of the refusal to bargain. See R. Gor *1026 man, Basic Text on Labor Law 533 (1976). 4 If the refusal persists until the time of the Board’s order, continuous make-whole relief may be appropriate. But if bargaining was resumed and carried forward to an impasse at some point between the initial refusal and the time of the Board’s order, make-whole relief must be circumscribed — at least in cases where the unilateral change did not violate the terms of a valid collective bargaining agreement. We hold, therefore, that where an employer and a union have bargained in good faith, 5 despite the employer’s prior unilateral changes in wages or conditions of employment, the employer’s ongoing liability for the unlawful unilateral changes terminates on the date when the parties execute a new agreement or reach a lawful impasse.
The record in this case indicates that the parties may have reached an “impasse” in their negotiations sometime during the first half of 1979. Because the Board’s failure to consider this possibility may have produced a substantial injustice, we remand the case with an instruction that Cauthorne’s ongoing make-whole liability would terminate on the date the parties reached an impasse. Upon remand, if the Board finds that the parties bargained to an impasse, then the Order must be modified.
III. Conclusion
For the foregoing reasons, we grant enforcement in part and deny it in part. The case is remanded to the Board for a redetermination, in accordance with the record evidence and pursuant to the principles enunciated in this opinion, of the period for which Cauthorne must contribute to the Union’s health and welfare trust fund.
So ordered.
