An Administrative Law Judge found Maverick Transportation, LLC (Maverick), liable for taking retaliatory action against Albert Brian Canter in violation of the Surface Transportation Assistance Act (STAA), 49 U.S.C. § 31105. The Department of Labor Administrative Review Board (ARB) affirmed. Maverick now petitions for review, which we deny.

In early October of 2003, Maverick hired Canter as a commercial vehicle driver. On November 21, 2003, while driving a tractor-trailer carrying a load for Maverick, Canter was involved in an accident in Pennsylvania which resulted in the death of a motorist. The Pennsylvania State Police placed the truck Canter had been driving out of service while they investigated the accident. During the post-accident inspection, a state trooper found the truck had defects in violation of a number of federal safety regulations. The defects included brakes out of adjustment, a fluid leak in the power steering box, a chaffing brake hose, and improperly secured dun-nage.
The trooper told Canter the truck would be released, provided the brakes were adjusted immediately and Maverick assured him the other violations would be corrected. Canter informed Maverick about the defects and the conditions for the truck’s release. Canter corrected the dunnage defect himself and Maverick arranged to have the truck’s brakes adjusted the following day. Canter then called Maverick to inform it two defects remained uncorrected. Maverick’s fleet manager, Robert Roberson, told Canter the local law enforcement officials had authorized Canter to drive the truck to Canter’s home, provided the remaining defects were corrected there.
Canter drove the truck approximately eighty miles to a truck stop near his home. There, on Maverick’s instructions, he dropped off the trailer containing the load he had been carrying. Maverick dispatched another driver to pick up Canter’s load but did not arrange for the remaining defects in the truck to be corrected at the truck stop. Canter then drove the truck another nine miles to his home.
As a result of the accident, Canter experienced depression. Maverick required Canter to take a month-long medical leave. Maverick did not arrange to have the truck’s defects corrected while Canter was on medical leave. On December 29, 2003, Canter was cleared to return to work. He chose to resign instead.
When Canter called to inform Maverick of his resignation, he spoke to Roberson. Roberson asked Canter to drive the truck an additional 200 to 250 miles to Maverick’s yard to return it. Canter refused to do so unless Maverick first fixed the remaining defects and agreed to provide him with transportation home. Canter told Roberson the truck had “too many deadline problems,” and the uncorrected defects with the truck were in violation of federal safety regulations. Canter then left the truck with the uncorrected defects at the truck stop where he had left its [1152]*1152trailer a month earlier, which he had authority to do, and informed Maverick of its location.
After Canter resigned, Roberson prepared an internal memo to submit to Maverick’s Rehiring Committee, in which Roberson indicated Canter had refused to drive the truck because it had “too many deadline problems.” Roberson also talked with Maverick officials about placing an abandonment notation in Canter’s Drive-A-Check1 (DAC) report. An abandonment notation has a negative effect on a driver’s ability to be hired and some employers refuse to hire drivers who have an abandonment notation in their DAC report. The Rehiring Committee ultimately placed an abandonment notation in Canter’s DAC report because Canter had refused to drive the truck to Maverick’s yard.
Canter secured employment one month after resigning from Maverick and worked for five different trucking companies between 2004 and 2008. After April 2008, Canter began experiencing difficulty finding work. Sometime on or after June 1, 2008, a recruiter told Canter information in his DAC report had prevented Canter from being hired. Canter requested the report and received it thirty days later, sometime in July or August of 2008. This was the first time Canter had seen his DAC report or the abandonment notation.
Canter’s final trucking job was with DSCO, Inc. (DSCO). He began working for DSCO in July 2008 and resigned in September 2008 when DSCO requested he violate federal hour-of-service regulations. Canter subsequently sought employment with K & B Transportation (K & B). Canter met all of K & B’s hiring requirements, but K & B refused to hire him because of the abandonment notation in his DAC report. Canter’s inability to find work negatively affected his mental state. He lost his home, became depressed, suffered a loss of appetite, and experienced suicidal thoughts. Canter eventually found work as a produce clerk.
On December 16, 2008, Canter filed a STAA complaint against Maverick with the Occupational Safety and Health Administration (OSHA) alleging retaliation. OSHA’s investigation concluded the complaint lacked merit, and Canter sought review by an Administrative Law Judge (ALJ).
Before the ALJ, Maverick argued Canter had not timely filed his STAA claim, which it also argued failed on the merits. In its recommended decision, the ALJ concluded the claim was timely. Relying on ARB precedent interpreting the STAA limitations period to begin to run when the employee receives definitive notice of an adverse action, the ALJ found Canter had filed his claim within 180 days of receiving definitive notice of the abandonment notation. The ALJ also concluded Maverick had unlawfully retaliated against Canter. The ALJ reasoned Canter’s refusal to drive the truck was protected by the STAA because the truck still had defects which violated federal regulations, and of which Maverick was aware. The ALJ reasoned in the alternative Canter had a reasonable fear of danger because of the truck’s unsafe condition. The ALJ further found the refusal had motivated Maverick to place the abandonment notation in Canter’s DAC report, which the ALJ concluded was an adverse action. Ultimately, the ALJ recommended awarding Canter back pay, compensatory damages for emotional distress, and other relief not currently at issue. Maverick sought review by the ARB.
[1153]*1153The ARB concluded the ALJ’s findings had all been supported by substantial evidence and affirmed the ALJ’s conclusion Canter’s claim was timely. The ARB, however, noted sua sponte the ALJ had erred in applying the standard under the STAA as it had existed prior to being amended in 2007, in ruling on Canter’s claim. Reviewing Canter’s STAA claim de novo under the post-2007 standard, the ARB concluded Canter had prevailed on his retaliation claim.2 Finally, the ARB affirmed the damage awards as supported by substantial evidence.
Maverick now petitions for review. In its petition, Maverick argues the ARB erred in (1) concluding Canter’s complaint was timely, (2) concluding Canter had proven his retaliation claim, and (3) affirming the damages as awarded by the ALJ.3

We review the ARB’s decision under the deferential standard articulated in the Administrative Procedure Act, 5 U.S.C. § 706(2). 49 U.S.C. § 31105(d). Under this standard we must affirm the ARB’s conclusions of law unless the same are arbitrary, capricious, an abuse of discretion, or otherwise contrary to law. 5 U.S.C. § 706(2)(A). We must also accept the agency’s factual findings if they are supported by substantial evidence. 5 U.S.C. § 706(2)(E). “Substantial evidence is relevant evidence that a reasonable mind would accept as adequate to support the [agency’s] conclusion.” Steed v. As-true, 524 F.3d 872, 874 (8th Cir.2008) (citing Young v. Apfel, 221 F.3d 1065, 1068 (8th Cir.2000)). As long as the ARB correctly applied the law and the ALJ’s “factual findings are supported by substantial evidence on the record considered as a whole” we will affirm the ARB’s decision “even though we might have reached a different decision had the matter been before us de novo.” Wilson Trophy Co. v. N.L.R.B., 989 F.2d 1502, 1507 (8th Cir. 1993) (citations omitted).

Maverick first contends the ARB’s conclusion Canter’s claim was timely was contrary to law. Maverick argues the STAA limitations period began to run when it placed the abandonment notation in Canter’s DAC report in 2004, and Canter did not file his claim until December 16, 2008. Under the STAA, a driver has 180 days to file a STAA claim from the date an alleged violation occurred. 49 U.S.C. § 31105(b)(1). The ARB, however, has interpreted the STAA to incorporate an exception to the general background rule of accrual that a claim accrues at the time of injury. See Osborn v. United States, 918 F.2d 724, 731 (8th Cir.1990) (describing the general rule). This exception is a version of the discovery accrual rule of federal common law, such that the [1154]*1154limitations period begins to run when the employee receives notice of the adverse action taken by the employer. See Eu-banks v. AM. Express, Inc., ARB No. OS-138, 4 (ARB Sept. 24, 2009) (holding the employee had 180 days to file a claim from the date the employee received final, definitive, and unequivocal notice of an adverse employment action). Maverick asserts the ARB’s interpretation is invalid.
In reviewing the Department of Labor’s interpretation of a statute it administers, we ask two questions. First, we ask “whether Congress has directly spoken to the precise question at issue.” Chevron, U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 842, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). “If ... Congress has not directly addressed the precise question at issue, the court does not simply impose its own construction on the statute, as would be necessary in the absence of an administrative interpretation.” Id. at 842M3, 104 S.Ct. 2778. Instead, we ask “whether the agency’s [interpretation] is based on a permissible construction of the statute.” Id. at 843, 104 S.Ct. 2778.
Maverick directs our attention to nothing which indicates Congress intended to exclude a version of the general discovery accrual rule from the STAA. As we find no indication Congress intended to exclude a version of the general discovery accrual rule from the STAA, we find nothing impermissible in the agency interpreting the STAA to incorporate it’s version of the rule. See Comcast of III. X v. Multi-Vision Elec., Inc., 491 F.3d 938, 944 (8th Cir.2007) (“In federal question cases, the discovery rule applies in the absence of a contrary directive from Congress.”) (internal quotation marks and citation omitted).
The dissent argues Chevron deference is inappropriate here. The dissent first asserts the Supreme Court in TRW Inc. v. Andrews, 534 U.S. 19, 27, 122 S.Ct. 441, 151 L.Ed.2d 339 (2001), expressly refused to approve the precedent of Comcast. The dissent, however, misreads TRW. In TRW, the Supreme Court considered a Ninth Circuit precedent which was, admittedly, very similar to the one set forth in Com-cast. Both precedents held that, absent some contrary directive from Congress, we incorporate the general discovery accrual rule into federal statutes. See TRW, 534 U.S. at 27, 122 S.Ct. 441; see also Com-cast, 491 F.3d at 944. Regarding this common holding, the Court merely noted it had not adopted the position as its own. TRW, 534 U.S. at 27, 122 S.Ct. 441. The Ninth Circuit’s precedent, however, exceeded the common holding by requiring Congress to make the contrary directive an express one. See id. It was this requirement of an express indication of intent to exclude the discovery accrual rule which the Court expressly refused to endorse. See id. (“And, beyond doubt, we have never endorsed the Ninth Circuit’s view that Congress can convey its refusal to adopt a discovery rule only by explicit command[.]”). The Supreme Court did not in TRW invalidate the presumption of reading the discovery accrual rule into federal statutes. See id. (noting TRW did not require the court to decide the extent of the presumption). Because it did not, Comcast remains good law.
The dissent next takes issue because the ARB’s version of the discovery rule differs from the common law discovery accrual rule we would be required to apply were we to interpret the STAA in the absence of the ARB’s decision. The ARB’s version of the discovery accrual rule holds a violation of the STAA accrues when the victim receives definitive notice of the injury, whereas the general discovery accrual rule would hold accrual to occur upon discovery of the injury or when the victim with due diligence should have discovered the injury. See TRW, 534 U.S. at 30, 122 S.Ct. 441; Comcast, 491 F.3d at 944. The ques[1155]*1155tion then, is whether the ARB, having decided to interpret the STAA to include an exception to the general background rule of accrual that an injury accrues at the time it occurs, can adopt an exception different from that widely accepted under the common law. We conclude it can. In doing so, we are mindful that where, as here, Congress is silent on the precise issue in question and the agency has spoken, it is not for the court to impose its own construction of a statute. Chevron, 467 U.S. at 842-43, 104 S.Ct. 2778. Rather we are to ask whether the agency’s interpretation is a permissible one. Id. at 843, 104 S.Ct. 2778. Unlike the dissent, we do not believe the ARB incorporating its version of the discovery rule into the STAA would effectively read out the STAA’s statute of limitations. Accordingly, we do not find the ARB’s interpretation to be an impermissible one, even though it differs from the rule we would be required to read into the statute if we were to interpret it in the first instance.
Thus, under Chevron we defer to the agency’s interpretation that the limitations period in the STAA begins to run when the employee receives notice of the employer’s adverse action. We also agree with the ARB that the ALJ’s finding Canter received such notice within 180 days of filing his claim was supported by substantial evidence. Accordingly, the ARB’s determination Canter timely filed his claim was not contrary to law.
IV
Maverick next challenges the ARB’s determination Canter prevailed on his retaliation claim. Maverick’s challenge is two-pronged. It argues the ALJ’s findings are unsupported by substantial evidence.4 Maverick also argues two of the ARB’s legal conclusions supporting the determination are contrary to law.
A retaliation claim based on a refusal to drive under the STAA is considered under a burden-shifting analysis. See 49 U.S.C. § 31105(a)(2)(b) (requiring STAA complaints to be determined under the standard set forth in 49 U.S.C. § 42121(b)(2)(B)). A complainant must first prove a prima facie case of retaliation by showing (1) the refusal to drive was protected under the STAA; (2) the employer knew of the protected conduct; (3) the employer took an adverse employment action against the complainant; and (4) the refusal to drive was a contributing factor in the employer’s decision to take the adverse action. 49 U.S.C. §§ 31105(a)(1)(B), 42121(b)(2)(B)®. Once a complainant sufficiently alleges a prima facie case, the employer may rebut the employee’s evidence by showing by clear and convincing evidence it would have taken the same action in the absence of the refusal. 49 U.S.C. § 31105(a)(l)(B)(ii).
A. Necessary Findings of Fact
Maverick’s arguments about the findings of fact amount to assertions the ALJ should have found the evidence supporting Maverick’s case as more compelling. Maverick mistakes the nature of our review, which is to determine whether the agency’s findings were supported by substantial evidence, not whether substantial evidence supports a contrary finding. See Warburton v. Apfel, 188 F.3d 1047, 1050 (8th Cir.1999) (“We may not reverse the [agency’s] decision merely because substantial evidence supports a contrary outcome.”).
After a review of the record as a whole, we conclude all of the facts found by the [1156]*1156ALJ, including those pertaining to the retaliation claim, were supported by substantial evidence. The pertinent findings include: (1) the truck had uncorrected defects, (2) Maverick knew about the defects and that the defects violated federal safety regulations, (3) Canter asked Maverick to fix the defects, (4) Canter refused to drive the truck because the defects remained uncorrected, (5) Canter’s refusal motivated Maverick to place the abandonment notation in Canter’s DAC report, despite being aware the defects remained uncorrected,5 and (6) it is likely K & B would have hired Canter had Maverick not placed the abandonment notation in his DAC report.
B. Necessary Legal Conclusions Maverick challenges as contrary to law the ARB’s legal conclusions that Canter’s refusal was protected activity, and the abandonment notation was an adverse employment action.
Protected Activity. The ARB concluded Canter’s refusal to drive the truck was protected by the STAA because the truck’s uncorrected defects violated federal safety regulations. In pertinent part, the STAA prohibits an employer from taking an adverse employment action against an employee who refuses to operate a vehicle because operation “violates a regulation ... of the United States related to commercial motor vehicle safety[.]” 49 U.S.C. § 31105(a)(l)(B)(i). At the time Canter refused to drive the truck, the fluid leak in the power steering box and the chaffing brake hose remained uncorrected. Driving the truck with either defect would violate federal safety regulations. See 49 C.F.R. § 393.1(c) (prohibiting the operation of vehicles not equipped in accordance with the requirements of part 393); id. § 393.45(b)(2) (requiring brake hoses to be secured against chaffing); id. § 393.209(e) (requiring all components of a power steering system be in operating condition and a power steering system not to leak).
Relying on 49 C.F.R. § 396.9(c), Maverick argues the defects were not violating safety regulations because they were not severe enough to place the truck out of service. We find this argument unpersuasive. Nothing in the text of section 396.9(c), which sets forth the standard for placing a vehicle out of service, limits violations to only those severe enough to place a vehicle out of service. Accordingly, we find nothing contrary to law about the ARB concluding Canter’s refusal was protected activity.
The ARB also concluded in the alternative that Canter’s refusal to drive was protected under the STAA because Canter had a reasonable fear of danger to himself or the public due to the truck’s unsafe condition. See 49 U.S.C. §§ 31105(a)(l)(B)(ii). However, because we must accept the ARB’s conclusion that Canter’s refusal to drive was protected because the uncorrected defects violated safety regulations, we need not review the ARB’s alternate basis for finding the refusal protected by the STAA.
Adverse Employment Action. Maverick next challenges as contrary to law the ARB’s conclusion that the placement of the abandonment notation in Canter’s DAC report was adverse to Canter. Maverick argues it was not adverse because Canter was initially able to obtain employment. Had Canter been aware of the abandonment notation when Maverick first placed it in his DAC report, such that the limitations period would have elapsed [1157]*1157while Canter was still able to obtain work, that might be the case. We have, after all, held the mere existence of a negative employment report not to be adverse in the absence of proof the report negatively affected future employment opportunities. See Turner v. Gonzales, 421 F.3d 688, 696 (8th Cir.2005) (holding negative employee review not adverse until it is used to deny a job opportunity).
Under the unusual circumstances of this case, however, we cannot conclude the ARB’s decision was contrary to law. The ARB had before it a finding supported by substantial evidence that Maverick’s placement of the abandonment notation actually led to Canter being denied employment. Because the ARB had that finding before it, its conclusion that the placement of the abandonment notation was adverse was not contrary to law.
Accordingly, Maverick’s challenge to the ARB’s conclusion that Canter prevailed on his retaliation claim fails.
V
Maverick also challenges the back pay and compensatory damage awards as contrary to law. It is undisputed that an employer who violates the STAA may be ordered to pay awards for back pay and compensatory damages. 49 U.S.C. § 31105(3)(A)(iii).
Maverick argues the calculation of the back pay award was contrary to law because the ALJ did not reduce or eliminate the award to account for Canter’s failure to mitigate damages by voluntarily leaving his position with DSCO. Typically, a complainant’s voluntary decision to leave an interim position constitutes a failure to mitigate damages that will toll the back pay period. E.E.O.C. v. Delight Wholesale Co., 973 F.2d 664, 670 (8th Cir.1992) (citing Brady v. Thurston Motor Lines, Ine., 753 F.2d 1269, 1277 (4th Cir.1985)). However, when the choice to voluntarily leave the interim position is “motivated by unreasonable working conditions,” the decision does not toll the back pay period. Id.; see also NLRB. v. Ryder Sys., Inc., 983 F.2d 705, 714 (6th Cir.1993) (“A claimant who leaves his job for a justifiable reason does not forfeit his right to additional back pay.”). Canter left DSCO because DSCO wanted him to violate hour-of-service regulations, an unreasonable working condition. Accordingly, the ALJ’s decision not to reduce the back pay award on that basis was not contrary to law.
At the last, Maverick contends the $75,000 the ALJ awarded Canter as compensatory damages for his emotional distress is contrary to law because it is excessive. Generally, “[a]wards for pain and suffering are highly subjective and the assessment of damages is within the sound discretion of the” factfinder. Christensen v. Titan Distribution, Inc., 481 F.3d 1085, 1097 (8th Cir.2007) (quoting Webner v. Titan Distribution, Inc., 267 F.3d 828, 836 (8th Cir.2001)). “We have intervened only in those rare situations where we are pressed to conclude that there is plain injustice or a monstrous or shocking result.” Hall v. Gus Const. Co., Inc., 842 F.2d 1010, 1017 (8th Cir.1988) (internal quotation marks and citations omitted).
Maverick argues the only evidence Canter offered of his depression was his own testimony, and most STAA. cases without medical evidence result in modest awards. “A plaintiffs own testimony can be sufficient for a finding of emotional distress, and medical evidence is not necessary.” Christensen, 481 F.3d at 1097 (citing Webner, 267 F.3d at 836). We also note the ARB makes its compensatory damage awards guided by the awards made in cases involving similar injuries. See Leveille v. N.Y. Air Nat’l Guard, ARB Case No. 98-079, 3 (ARB Oct. 25, 1999) (discussing criteria for making compensa[1158]*1158tory damage awards). Our review of the ARB’s case law indicates its awards for compensatory damages have varied significantly. Although $75,000 is near the high end of the range, the ARB has made similar awards in other cases. See, e.g., Mi-chaud v. BSP Transp., Inc., ARB Case No. 97-113, 9 (ARB Oct. 9, 1997) (affirming award of $75,000 on evidence of major depression and loss of home and savings). Accordingly, we find no abuse of discretion in the ALJ’s award of $75,000 as compensatory damages for Canter’s emotional distress.

For the foregoing reasons, we deny the petition for review.
