OPINION OF THE COURT
88 Transit Lines, Inc. (the “Company”) has petitioned this court for review from a final order of the National Labor Relations Board entered in supplemental backpay proceedings
(88 Transit Lines, Inc.,
I.
The supplemental backpay proceeding followed our decision enforcing an earlier NLRB finding that the Company discriminated against its employees when, shortly after a representation election conducted at the Company’s facility, the Company replaced its transit run schedule which had been in effect for many years, Schedule B, with a Schedule C, thereby decreasing the total number of fixed transit runs by one and eliminating run 14, reducing the number of transit runs which were open for bids, and making the fixed runs subject to discretionary assignment by the Company rather than open for bids based on seniority. The Board found that the scheduling change violated 29 U.S.C. §§ 158(a)(1) and (3) and ordered the Company to “make employees whole for any losses they may have suffered as a result of these unlawful actions” and this court entered judgment enforcing the order.
See 88 Transit Lines, Inc.,
When the parties failed to agree on the amount of backpay, the Regional Director issued a backpay specification alleging the amount owed to the discriminatees. Following a hearing, an ALJ recommended amending the backpay specification in two aspects. First, the ALJ recommended not awarding backpay to fourteen replacement workers who had been hired during the backpay period, reasoning that “such employees have no losses to be restored to them, since they were not employed at the time of the elimination of run 14. Second, the ALJ recommended treating as interim earnings any amount by which post-unfair labor practice earnings exceeded employee earnings during the base-period year.
The Board refused to adopt these recommended amendments to the backpay specification. It ordered backpay for all twenty-three employees, including the fourteen replacement employees, and refused to reduce their gross backpay by post-unfair labor practice earnings which exceeded the base period earnings because to do so would “inappropriate[ly] appl[y] ... the interim earnings’ concept to a case involving a violation other than discharge from employment, and ... effectively resolve[ ] uncertainties in favor of the wrongdoer.” The Board ordered backpay to be calculated in accordance with the original specification, plus interest and less tax withholdings required by law.
This court has jurisdiction under 29 U.S.C. § 160(e) and (f). On questions of law, appellate review of the Board’s decision is plenary, although that decision is entitled to deference due to the Board’s expertise in labor matters.
NLRB v. Louton, Inc.,
II.
It is undisputed that the backpay specification issued by the Regional Director correctly designated the backpay period to be between November 29, 1987, when the Company first instituted the schedule change, and August 18,1991, when the Company restored *826 run 14, a total of 194 weeks. Both parties also agree that the implementation of schedule C represented a loss to the bargaining unit of 2% hours of work per day, or 13| hours per week, and that the wage rate for the discriminatees was $6.75 per hour.
In arguing that the Board’s order is not supported by substantial evidence and an abuse of discretion, the Company raises essentially three claims of error: (1) the Board erred in finding that the fourteen replacement drivers were entitled to compensation; (2) the Board erred in declining to treat as interim earnings the amount by which the discriminatees’ post-unfair labor practice annual earnings exceeded their base-period year earnings with the Company; and (3) the ALJ’s post-hearing amendment of the back-pay specification denied the Company procedural due process. 1
The Company argues that the fourteen replacement drivers are not entitled to compensation for backpay because they were hired after the schedule change went into effect and, thus, they suffered no change in their schedules entitling them to compensation. By way of analogy, it relies on
Systems Management, Inc. v. NLRB,
The Company’s rebanee on Systems Management, however, is misplaced. In Systems Management, this court enforced a cease and desist order and a make-whole order where a successor employer failed to offer employment to its predecessor’s employees or to recognize their bargaining representative, Local 29, and instead contracted with another union, Local 327, at a substantially lower wage rate. Id. at 301. The court declined to enforce a backpay award for new hires affiliated with Local 327 who “if anything ... were beneficiaries of [the employer’s] discriminatory conduct, because the result of [the employer’s] decision not to employ the Local 29 workers culminated in the employment of the Local 327 workers.” Id. at 308.
This case presents quite different facts. The fourteen replacement employees were hired to replace original bargaining unit employees who departed in the normal course of business. Therefore, the replacement employees cannot be said to be the “beneficiaries” of the discriminatory conduct. Rather, the change in schedule caused a loss of work for the entire bargaining unit. The Board correctly found that the remedy was to inure to the benefit of the entire bargaining unit. The award of backpay to the fourteen replacement employees was not “ ‘punitive or confiscatory’ ” and was “ ‘reasonably adapted to the situation that callfed] for the redress.’ ”
See Frito-Lay, Inc. v. NLRB,
The Company’s second argument is that the Board’s refusal to deduct post-unfair labor practice earnings which exceeded base-year earnings from the gross backpay violated the long-standing principle that discrimi-natees must mitigate damages and that gross backpay must be reduced by interim earnings to derive a net backpay award. The Company refers us to a leading case on the mitigation doctrine,
NLRB v. Madison Courier, Inc.,
This argument must also fail. It is true that mitigation of loss of earnings is a cardinal principle in the development of re
*827
medial orders under the National Labor Relations Act.
See Tubari Ltd. v. NLRB,
III.
For the reasons set forth, we will deny the Petition for Review of the Order of the National Labor Relations Board issued on July 12, 1994 and grant the Cross-Application for Enforcement of the Order of the National Labor Relations Board issued on July 12, 1994.
Notes
. The Company also argues that the backpay specification failed to establish any loss of earnings by any employee during the backpay period and was therefore speculative and an undeserved windfall to the employees. The Company agrees that a compliance officer may employ a formula other than one of the standard formulae when application of the standard formula is not feasible. In this case, the General Counsel specified the names of the twenty-three discriminatees and the number of hours each worked during the backpay period and, applying the backpay formula, calculated that each discriminatee lost $4.04 per week for each week worked during the backpay period. The backpay formula adopted by the Board is reasonable in light of the nature of the violation and is entitled to our deference.
See NLRB v. Seven-Up Bottling Co.,
. The Company argues that the Board erred when it suggested in its Supplemental Order that the interim earnings principle applies only with respect to employees who have been unlawfully discharged. It cites
Ironton Publications, Inc.,
. The Company's final argument is that the ALJ's post-hearing amendment of the backpay specification did not afford the Company an adequate opportunity to produce evidence of employee interim earnings. In light of our holding that the backpay award need not be reduced by what the Company characterizes as "interim earnings," consideration of the Company’s contentions on this issue is unnecessary.
