MEMORANDUM *
We affirm the decision of the National Labor Relations Board (NLRB) in all respects except the NLRB’s conclusion that Bridgestone/Firestone, Inc. (BFS) engaged in solicitation in the three-store unit, which we reverse. We grant in part the NLRB’s petition for enforcement.
1. THE COMPLAINT AMENDMENTS
A. Section 10(b)
Section 10(b)’s six-month statute of limitations applies to the period between the occurrence of the alleged unfair labor practice and the filing of the charge, not the filing of the complaint.1 Thus, amending the complaint did not violate the limitations period.2 However, Section 10(b) circumscribes the NLRB’s ability to amend complaints in a different respect: the statute authorizes the NLRB to “issue[ ] complaints only when charges have been filed and not on its own initiative.”3 Thus, “[t]he instant case does not involve an untimely charge but merely whether the [Union’s] chargefs] ... [are] sufficient” 4 to support the complaint amendments.
In this circuit, the original charge and the complaint amendments “need be close enough only to negate the possibility that the Board is proceeding on its own initiative rather than pursuant to a charge .”5 *451Similarly, the NLRB has determined that complaint amendments may relate back to the original charges if they (1) “involve the same legal theory,” (2) “arise from the same factual circumstances,” and, in some cases, if (3) “a respondent would raise similar defenses to both.”6
The Union originally charged that BFS unlawfully refused to bargain. BFS refused to bargain because it concluded that a majority of employees had signed union decertification petitions. Thus, the Union’s charges inevitably raised the issue of the validity of the petitions.
The solicitation allegations directly challenged the validity of the petitions. The direct dealing allegations indirectly challenged the petitions’ validity because the allegations implied that BFS fostered the employee dissatisfaction that was at the root of the petition drive. Thus, the solicitation and direct dealing allegations arose from the same factual circumstances and involved the same legal theory as the original charges. Similarly, the legal and factual issues raised by the complaint amendments were close enough to those raised by the original charges to negate the possibility that the NLRB was acting on its own initiative.
The fact that BFS could have raised different defenses to the amendment allegations than to the original charges is irrelevant. The NLRB’s test primarily emphasizes the factual connection between the charge and the complaint.7 Thus, the “same defenses” prong need not be applied if the factual and legal similarity prongs settle the matter.8 Even when the “same defenses” prong does apply, the inquiry is whether the charge and complaint allegations “allege the same unlawful object,”9 not whether there are legal distinctions between the various defenses that might be raised.
The charge and complaint allegations are sufficiently similar, factually and legally, to settle the question of whether amendments to the complaint relate back to the original charges. Both the charge and the complaint ultimately allege the same object, an unlawful refusal to bargain. Accordingly, the assertion that BFS would mount different legal defenses to the amendment allegations than to the original charges does not preclude a finding that the original charges and the complaint amendments are closely related.
B. Due Process
The only due process issue is whether the complaint amendments were fully and fairly litigated because “[ejven when the complaint is devoid of notice of the unfair labor practice, due process is satisfied by full litigation of the issues.”10
1. Direct Dealing.
BFS elicited Garcia’s testimony about BFS’s decision to seek employee authorizations before releasing the employees’ home addresses to the Union — the conduct that formed the basis of the direct dealing allegations. BFS therefore cannot claim *452that the evidence was unfairly introduced.11 In addition, BFS was afforded an opportunity for redirect after the Union and the administrative law judge (ALJ) cross-examined Garcia about the employee authorizations decision, but declined.12 BFS also declined an opportunity to present additional evidence — including exculpatory evidence — at the end of the hearing.13 The direct dealing allegations were therefore fully and fairly litigated within the meaning of this court’s precedents.
2. Solicitation.
Four witnesses — including one called by BFS — testified that Gallo and Hook urged employees to sign the petition or to decertify the Union, discussed the relative benefits of union versus non-union shops, or discussed what benefits would be available if the employees rejected the Union. Three of these witnesses testified primarily, if not exclusively, to what Gallo and Hook said and did during the store visits. In other words, the hearing transcript is “replete with evidence”14 of solicitation.
BFS did not object to the adverse testimony and cross-examined the witnesses, with the exception of Foster, a witness BFS called and expressly declined to examine on redirect. BFS also called two witnesses to testify that Gallo and Hook said and did nothing improper during the visits. Finally, BFS declined to present additional evidence when afforded the opportunity, and it is difficult to imagine what other exculpatory evidence BFS could have introduced. Accordingly, the solicitation allegations were fully and fairly litigated.
BFS’s argument that it, like the employer in Presto Casting Co. v. NLRB,15 was taken off-guard and “was not prepared at the hearing to come forward”16 with evidence to defend itself, lacks merit. BFS called two witnesses to testify that there had been no solicitation and had a third witness ready to so testify. Thus, BFS was prepared to come forward with evidence regarding the solicitation allegations. In addition, as previously discussed, the amended allegations in this case were factually and legally intertwined with the original unfair labor practice charges, unlike those in Presto.17 Accordingly, BFS cannot credibly claim to have been surprised or taken off-guard by the amended allegations.
*453II. THE THREE-STORE UNIT
We reverse the NLRB’s conclusion that BFS engaged in solicitation in the three-store unit. Gallo and Hook never visited the stores in the three-store unit. In addition, the ALJ’s conclusions18 that the two bargaining units shared a “total community of interests” and that there was a “causal relationship” between the withdrawal of union recognition in the ten-store unit and the circulation of petitions in the three-store unit lack record support. If anything, the record indicates that a three-store unit employee started the three-store unit petition drive independently, out of his own dissatisfaction with the Union. Finally, the ALJ improperly shifted the burden by citing BFS’s failure to present evidence that solicitation of employees in the ten-store unit did not taint BFS’s withdrawal of recognition in the three-store unit.19 Thus, the ALJ’s conclusion that BFS engaged in solicitation in the three-store unit was not supported by substantial evidence and was based on an incorrect application of the law.20
li] However, we affirm the NLRB regarding direct dealing in the three-store unit. BFS implemented the employee authorization requirement in the three-store unit. The NLRB concluded that the requirement tended to increase employee disaffection with the Union, a reasonable inference supported by the record.21 Finally, the fact that decertification petitions were circulating in the three-store unit was not a sufficient basis for Gill to delay in responding to the Union’s information request.22 Substantial evidence therefore supports the NLRB’s conclusion that BFS engaged in direct dealing in the three-store unit.
III. THE BARGAINING ORDER [5] We affirm the bargaining order except as it relates to solicitation in the three-store unit. A bargaining order is appropriate where the Union once enjoyed majority support and an alternative remedy — such as a cease and desist order or an election — “would in effect be rewarding the employer and allowing him ‘to profit from [his] own wrongful refusal to bargain.” ’23 Such is the case here. The *454Union had majority support until the collective bargaining agreements (CBAs) expired.24 BFS based its withdrawal of Union recognition and refusal to bargain on petitions tainted by BFS’s unfair labor practices.25 Thus, NLRB’s bargaining order prevents BFS from profiting from its wrongful refusal to bargain. Accordingly, the NLRB did not abuse its discretion in choosing to impose a bargaining order.26
However, because we have concluded that the allegation of solicitation in the three-store unit was not supported by substantial evidence, we grant enforcement of the bargaining order only in part. We deny enforcement of the order insofar as it implies or assumes that BFS engaged in solicitation in the three-store unit or requires BFS to take any steps to remedy or address the alleged solicitation in the three-store unit. We grant enforcement of the order in all other respects.
IV. CHECKOFF DUES
The NLRB properly found the complaint did not allege a failure to make check-off dues payments, thus the issue was not properly litigated at the hearing.27 The NLRB’s decision to refuse the Union’s checkoff dues request is therefore supported by substantial evidence.28
