Opinion for the Court filed by Circuit Judge ROGERS.
New York Rehabilitation Care Management, LLC and New York Center for Rehabilitation Care, Inc. (together “the Company”) petition for review of a decision and order of the National Labor Relations Board finding that they violated Section 8(a)(5) and (1) of the National Labor Relations Act (“the Act”), 29 U.S.C. § 158(a)(5), (1). The principal issue is whether the Board abused its discretion in vacating a union certification and ordering a new representation election. The Company contends that the Board erred by considering issues beyond the scope of a representation proceeding. Under the unusual circumstances involved, we find no abuse of discretion by the Board in revoking the union certification and ordering a new election in a representation proceeding notwithstanding the extant collective bargaining agreement (“CBA”). Accordingly, because the Company’s other defenses to its conceded refusal to bargain with the union that prevailed in the second election fail, we deny the petition and grant the Board’s cross application for enforcement of its order.
I.
Prior to 2002, the Company operated Lyden Care Center (“Lyden”), a 114-bed skilled nursing facility in New York City. *1073 For more than twenty years, Local 1199, New York’s Health and Human Service Employees’ Union, Service Employees International Union (“Local 1199”) represented Lyden’s employees.
On November 15, 2001, the Company submitted an application to the New York Department of Health to open the New York Center for Rehabilitation Care (“NY Center”), a new, 280-bed skilled nursing facility to be located a few blocks from Lyden, stating that it intended to close Lyden and transfer its patients to the new facility. The application stated that the Company anticipated that N.Y. Center would be at eighty percent occupancy within twelve months. The Company estimated that it would need approximately 300 on staff once N.Y. Center reached capacity. To effectuate this plan, the Company intended to increase the number of staff as patients arrived, hoping to transfer staff from Lyden to N.Y. Center when Lyden closed. When Local 1199 attempted to obtain information about N.Y. Center and any plan to transfer its member-employees to the new facility, the Company provided none.
On January 25, 2002, Local 300S, Production, Service and Sales District Council, United Food and Commercial Workers Union (“Local 300S”) filed an election petition with the Board to become the collective bargaining representative for employees at N.Y. Center. Neither the Company nor Local 300S provided the Board with any information about Local 1199’s interest in the election, notwithstanding Local 1199’s lengthy representation of Lyden’s employees. Nor did they inform the Board of the Company’s plan to expand significantly N.Y. Center’s workforce in the near future. Under the terms of a stipulation between the Company and Local 300S, only those employed at N.Y. Center on January 12, 2002 would be eligible to vote. As of that date, N.Y. Center had forty-one employees, thirty-seven of whom had worked less than eight hours. Despite being a skilled nursing facility, only fourteen of the eligible employees held jobs involving patient care, all fourteen of whom stopped working at N.Y. Center the week before the first patient arrived. Following an election held on February 22, 2002, the Regional Director of the Board certified Local 300S as the representative of N.Y. Center employees. On April 26, 2002, three days before N.Y. Center opened its doors, the Company and Local 300S entered into a four-year CBA. Lyden closed on October 9, 2002, transferring one hundred patients and seventy-seven employees to N.Y. Center, and by October 16, 2002, N.Y. Center had more than 200 employees, only twelve of whom had been eligible to vote in the February 22 election.
On October 25, 2002, Local 1199 filed a petition with the Board to invalidate Local 300S’s certification and hold a new election. The Board considered Local 1199’s petition in a representation proceeding, rather than an unfair labor practice proceeding. Following a four-day hearing, the Regional Director found that: (1) the two entities petitioning for review constitute a single employer under the Act, (2) the Company and Local 300S had failed to notify the Board about Local 1199’s interest in the representation election, and (3) the employees voting in the February 22, 2002 election did not constitute a “substantial and representative” complement of the “reasonably foreseeable future workforce” of N.Y. Center. The Regional Director therefore revoked Local 300S’s certification because it “was not the lawful ... representative of N.Y. Center’s employees at any time” and “[t]o permit the election results to stand would be contrary to the Act’s guarantee that employees have the right, of their own choosing, to select or reject a bargaining representative.” The *1074 Regional Director declined to apply the contract bar doctrine and ordered N.Y. Center to hold a new election with both Local 300S and Local 1199 on the ballot.
Local 1199 won the second election, held on March 11, 2004, by a vote of 200 to 5. According to an affidavit the Company proffered to the Regional Director, Local 1199 representatives had stood at the entrance to N.Y. Center on election day, distributing hats, T-shirts, and pins to employees, and providing coffee and food. The Company filed objections to the election on March 23, 2004 based on Local 1199’s electioneering, asking the Board to set it aside. The Regional Director overruled the Company’s objections on May 20, 2004 and certified Local 1199 as the collective bargaining representative of employees at N.Y. Center. When the Company appealed, the Board declined to review the Regional Director’s determination, finding that the Company had raised “no substantial issues” with respect to the election. NY Center nonetheless refused to bargain with Local 1199. When Local 1199 complained, the Board commenced an unfair labor practice proceeding. The Company conceded that it had refused to bargain with Local 1199, but contended that Local 1199’s certification was invalid. Prior to the Board’s decision, but after the Company’s refusal to bargain, Local 1199 disaffiliated from the AFL-CIO.
By decision and order of July 29, 2005, the Board granted summary judgment, finding that the Company’s refusal to bargain with Local 1199 violated Section 8(a)(5) and (1) of the Act. The Board concluded that all issues raised by the Company with respect to Local 1199’s certification were, or could have been, raised in the underlying representation proceeding and that the Company offered neither to adduce newly discovered evidence nor to show any special circumstances that would require the Board to reexamine its decision to certify Local 1199. Affirmatively, as a remedy for the violation, the Board ordered the Company to bargain with Local 1199, to embody any understanding reached in a signed agreement, and to post copies of a remedial notice. The Board denied the Company’s motion for reconsideration, which argued that an issue of fact existed as to whether Local 1199, after its disaffiliation from the AFL-CIO, remained the same union that employees had chosen as their representative. The Company now petitions for review, raising anew the objections it had raised to the representation proceeding and the second election, and the unfair labor practices proceeding. The Company, however, has not challenged the Board’s determination that the two entities petitioning for review constitute a single employer under the Act.
II.
In addressing the Company’s several challenges to the Board’s decision and order, the court does so cognizant that the Board has “broad discretion ‘to assess the propriety and results of representation elections,’ ”
AOTOP, LLC v. NLRB,
A.
The Company challenges the Board’s procedures in ordering a new election, contending that the Board may impugn a CBA only in an unfair labor practice proceeding and not in a representation proceeding. The procedure followed by the Board, the Company continues, improperly circumvented the six-month statute of limitations applicable to unfair labor practice proceedings. See 29 U.S.C. § 160(b). The Board proceeded in two steps: First, the Board revoked Local 300S’s certification because the union and the Company failed to notify the Board of Local 1199’s interest and because a substantial and representative complement of employees did not exist at the time of the first election. Second, the Board ordered a new election, declining to apply the contract bar doctrine because it found that Local 300S had never been validly certified as the representative of N.Y. Center employees. We find that the Board did not abuse its discretion by adjudicating these issues in a representation proceeding.
The Board has stated that “unfair labor practice issues
as such
” can only be adjudicated in an unfair labor practice proceeding.
All County Elec. Co.,
Contrary to the Company’s position, the Board’s decision not to apply the contract bar doctrine in a representation proceeding is consistent with the Act and with Board precedent, even though the Board relied upon facts beyond the four corners of the CBA, namely the facts that justified revoking Local 300S’s certification. The Board has previously resolved the applicability of the contract bar doctrine in representation proceedings,
see General Extrusion Co.,
The Company has cited no authority to the contrary. Although the Company
*1076
characterizes
General Extrusion
as “not permitting] the litigation in a representation (contract bar) case of the issue of whether a company is in normal operation,” Petitioner’s Br. at 15, that decision does not announce such a blanket rule. Further,
General Extrusion
considered the circumstances under which the number of those employed at a company at the time a CBA is entered into can justify ordering a new election despite that CBA.
Although the Company also contends in its reply brief that the Board offered an inadequate explanation for its decision not to apply the contract bar doctrine, we decline to entertain this contention; in order to prevent the “sandbagging” of another party, “we have generally held that issues not raised until the reply brief are waived.”
See Bd. of Regents of the Univ. of Wash. v. EPA,
B.
The Company’s other defenses to its conceded refusal to bargain with Local 1199 also do not support granting the Company’s petition.
The Company contends that the circumstances surrounding the first election did not justify the revocation of Local 300S’s certification. The record before the Board indicated two independent grounds for the revocation: failure to give proper notice and the absence of a substantial and representative complement of employees at the time of the first election. As the Board points out, by failing to address the failure to give proper notice issue in its opening brief, the Company has forfeited any right to challenge either the Board’s finding that it failed to notify the Board of an interested party or the Board’s conclusion that this warranted revocation of Local 300S’s certification.
See Bd. of Regents of the Univ. of Wash.,
The Company further contends that the Lyden employees should have been accreted to Local 300S. According to Board precedent, an accretion is defined “as ‘the addition of a relatively small group of employees to an existing unit where these additional employees share a sufficient community of interest with the unit employees and have no separate identity. The additional employees are then properly governed by the unit’s choice of bargaining representatives.’ ”
Safety Carrier, Inc.,
The Company’s objection to the Board’s summary disposition of its objections to the second election also lacks persuasive force. A party seeking to overturn a Board-administered election bears a heavy burden.
See Kwik Care Ltd. v. NLRB,
Here, the Company’s paltry evidentiary offering provides an insufficient basis to show that the Board was required to hold an evidentiary hearing.
See Amalgamated Clothing Workers of Am. v. NLRB,
Finally, the Company contends that the Board erred in refusing to reconsider its decision that the Company had a duty to bargain with Local 1199 after the union disaffiliated from the AFL-CIO. According to the Company, the union’s disaffiliation changed its identity so that new Local 1199 was not the Local 1199 that won the election. The court need not address this *1078 issue because the Company does not challenge the alternative ground on which the Board relied, namely that the disaffiliation occurred after the Company refused to negotiate.
Accordingly, we deny the petition for review and grant the Board’s application for enforcement of its order.
