Opinion for the Court filed by Circuit Judge GARLAND.
The National Labor Relations Board issued an order requiring Halle Enterprises, Inc. to reinstate and make whole eleven employees whom the company had fired for complaining about wages, hours, and working conditions. The question before us is whether the company’s voluntary offer of reinstatement to four of the employees tolled their right to backpay. The Board held that it did not, because the offer was not firm, clear, and unconditional. Substantial evidence supports the Board’s finding, and we therefore deny the company’s petition for review and grant the Board’s cross-application for enforcement of its order.
I
Halle Enterprises is in the business of building homes and managing apartment complexes. On the morning of November 4, 1997, eleven of the company’s maintenance technicians complained to their supervisor about wages, hours, and working conditions, including the unavailability of safety equipment. Not long thereafter, Wayne Ellis, the company’s property manager, arrived on the scene and fired all eleven workers. The next day, November 5, Ellis told the employees that they could have their jobs back if they filled out new applications. When the employees learned that Ellis’ offer did not include their current benefits and seniority, they refused.
The National Labor Relations Board (NLRB) held that Halle Enterprises violated section 8(a)(1) of the National Labor Relations Act by firing the eleven employees on November 4.
Halle Enters., Inc.,
380 N.L.R.B. No. 163,
The NLRB’s Administrative Law Judge (ALJ) had determined that Warren Halle’s unconditional offer tolled the company’s obligation to pay the four employees back-pay as of November 7, despite Ellis’ subsequent insistence that they sign a waiver as
*271
a condition of reinstatement. The Board disagreed with the ALJ. It held that Ellis’ subsequent demand superseded Halle’s initial offer and rendered the company’s offer conditional.

When the NLRB determines that an employer has unlawfully discharged an employee, its normal course is to issue a make-whole order requiring reinstatement and backpay.
See Darr v. NLRB,
Halle Enterprises concedes that it committed an unfair labor practice by discharging the eleven employees. It challenges neither the Board’s order requiring their reinstatement, nor the mandate to provide full backpay for the seven junior technicians. The company attacks the order only to the extent that it awards back-pay to the four senior employees subsequent to the date of Halle’s reinstatement offer. The company does not dispute that Ellis’ offer was conditional, and that if his was the last offer received by the four senior technicians, it would have superseded Halle’s offer and prevented tolling of their backpay. The company contends, however, that it was Halle’s offer that came last.
According to company counsel, the only issue in this case is whether the Board was correct in finding that Ellis’ conditional offer was the last one communicated to the employees. We adopt this formulation of the issue on appeal with one caveat. Our role is not to determine de novo whether the Board’s factual finding was correct. Rather, we are limited to determining whether it is “supported by substantial evidence on the record considered as a whole.” 29 U.S.C. § 160(e);
see Universal Camera Corp. v. NLRB,
We conclude that there is substantial evidence to support the Board’s finding. Israel Flores testified that Ellis’ November 10 offer of reinstatement, which included the waiver condition, was the last offer the employees received from the
*272
company. J.A. 66, 68-69. Warren Halle himself testified that he "probably" made his unconditional offer two or three days after the November 4 incident, J.A. 187, which the AU concluded put it on or about November 7-several days before Ellis' conditional offer of November 10. Halle Enters.,
The company’s only response is that, notwithstanding Halle’s testimony, it was' logically impossible for him to have made his unconditional offer until after Ellis insisted upon a waiver on November 10. The company notes that Halle testified he told Flores that the employees would not have to sign anything in order to return to work, and that the ALJ credited that testimony. Id. at *5. It would not have been logical for Halle to have referred to the signing of a document, the company argues, unless Ellis’ insistence upon a waiver had come before.
This purported inconsistency within the testimony of the employer's own president is a weak reed upon which to base a claim that the NLRB lacks substantial evidence to support its factual finding. In any event, there is no logical conundrum here. The company's argument assumes that November 10 was the first time Ellis told the employees they would have to sign a waiver in order to regain their jobs. But one of the fired employees, Jose Alfaro, testified that Ellis first made that demand the day after the firings-November 5-when he offered all eleven employees reinstatement, but without benefits or seniority. See J.A. 93 (Alfaro Tr.) ("[Hie told us that we were going to lose all of our benefits, and that he wanted us to sign a note stating that there was nothing that we could do against the company."). The company did not cross-examine Alfaro on the point, and offered no rebuttal. Moreover, Halle did not testify as to how or when he learned of the waiver requirement, nor even expressly associate it with Ellis.
In light of the above, Halle’s testimony plainly does not render it impossible “for a reasonable jury to reach the Board’s conclusion” that Ellis’ conditional offer of November 10 was the last one the employees received.

One final loose end remains to be secured. In addition to Halle and Ellis, a third manager-Vice President Joe Dodson-also made an offer of reinstatement to the four senior employees. The AU found, however, that Dodson's offer was conditional, and was made after Halle's unconditional offer and before Ellis' conditional one. Halle Enters.,
The company disputes the ALJ’s findings on both counts, contending that Dodson’s offer was unconditional and that it came after Ellis’. But even if Dodson
intended
his offer to be unconditional, its wording hardly met the employer’s burden of
communicating
an offer that was “firm, clear, and unconditional.”

IV
Substantial evidence supports the NLRB’s determination that the ultimate offer of reinstatement made by Halle Enterprises to its unlawfully discharged employees was conditional. As a consequence, that offer did not toll the employees’ entitlement to backpay. We therefore deny the petition for review and grant the Board’s cross-application for enforcement.
Notes
. Section 8(a)(1), 29 U.S.C. § 158(a)(1), ■ makes it an unfair labor practice “to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed” in section 7 of the Act, which include the right to engage in concerted activities for the purpose of “mutual aid or protection,” 29 U.S.C. § 157.
. According to Dodson, he told the employees: "You would return under the same conditions that you left insofar as salary, benefits. The only thing that they would not receive is any money for time away from their job. No *273 other conditions were made.” J.A. 177 (emphasis added).
. See J.A. 65-69 (Flores Tr.) (testifying that, although Dodson said the four senior employees should go back to work, when they arrived Ellis insisted upon a waiver, and that thereafter the company did not again offer reinstatement); J.A. 162 (Medina Tr.) (testifying that, although Dodson said he wanted the four to go back to work, when they came to the office Ellis required them to sign the waiver document before starting).
