Barrick Goldstrike Mines Fired Worker After FMLA Leave for Injury
Tomas Perez, an underground haul truck driver, was terminated after reporting a workplace chest injury and taking protected medical leave. The company hired private investigators to surveil him and then fired him for allegedly faking his injury.
Tomas Perez reported a chest injury after his haul truck collided with a mine wall. His doctor certified him for protected leave under the Family and Medical Leave Act. Instead of accepting the medical certification, Barrick hired private investigators to follow Perez for three days, recorded him doing activities at home, then fired him for allegedly faking his injury. Although a jury ultimately sided with Barrick, the case exposes how corporations use surveillance and aggressive tactics to challenge worker injury claims and avoid costs associated with protected leave.
This case shows how employers can use private surveillance and legal maneuvering to challenge workers who report injuries and take protected leave.
The Allegations: A Breakdown
| 01 | Perez was operating an underground haul truck when it collided with the mine wall, thrusting his chest into the driver’s seat armrest and causing injury. He reported the incident at the end of his shift, hours after it occurred, as required by company policy to report all injuries immediately. | high |
| 02 | Dr. Black examined Perez and found no outward signs of injury and no abnormalities in X-rays, but diagnosed him with a chest wall contusion and muscle spasms based on Perez’s description of the accident and his pain. The doctor prescribed muscle relaxants and certified Perez to remain off work for five days. | medium |
| 03 | At a follow-up appointment, Perez reported continued severe pain from certain movements. Dr. Black certified him to remain off work for another eleven days, bringing his total medical leave to eighteen days before he was approved to return with no restrictions. | medium |
| 04 | Barrick found no physical evidence that Perez’s truck had collided with the mine wall. An employee emailed management that one of Perez’s friends said Perez was faking a work-related injury to take time off to work on personal business, specifically fixing rental properties. | high |
| 05 | Barrick hired a private investigator to follow Perez and confirm whether he was fraudulently taking FMLA leave. Over three days, the investigator captured video of Perez driving, gambling at a casino, performing repair work at his rental property, repeatedly lifting and holding both arms over his head, and carrying and using a power drill and other tools. | high |
| 06 | When Perez returned from leave, Barrick confronted him with the employee report and investigator findings. Perez responded that he had nothing to say. Barrick then fired him after concluding he had faked his injury and violated company policy. | high |
| 07 | Perez filed suit claiming Barrick violated the Family and Medical Leave Act by interfering with his protected leave rights and wrongfully terminating him. He also claimed retaliatory discharge in violation of Nevada public policy for filing a worker’s compensation claim. | high |
| 08 | A jury found that Perez failed to prove by a preponderance of evidence that he suffered a serious health condition preventing him from performing his job or that Barrick terminated him because he sought protected leave. The court ruled in favor of Barrick on all claims. | medium |
| 01 | The FMLA states that employers may require additional medical opinions when they have reason to doubt the validity of a doctor’s certification, but this language is permissive, not mandatory. Barrick used this permissiveness to skip obtaining second medical opinions and instead hired private investigators. | high |
| 02 | The Ninth Circuit held that the FMLA does not require an employer to present contrary medical evidence before contesting a doctor’s certification of a serious health condition. This ruling allows employers to dismiss professional medical opinions without obtaining their own medical evaluations. | high |
| 03 | The court permitted the jury to consider non-medical evidence, including surveillance footage, to determine whether Perez had a serious health condition, effectively allowing a jury of laypeople to override a licensed physician’s medical certification without contrary medical expert testimony. | high |
| 04 | Perez argued the district court should have instructed the jury that only contrary medical evidence could defeat a doctor’s FMLA certification. The appeals court rejected this argument, affirming that employers can use any type of evidence to challenge medical certifications in court. | high |
| 05 | The appeals court joined the Second, Fourth, Sixth, and Eighth Circuits in holding that employers do not need to seek recertifications or second medical opinions before contesting FMLA certifications in litigation. This creates a uniform federal standard that favors employer discretion over medical professional judgment. | medium |
| 06 | The court found no prejudicial error in the jury instructions, meaning the legal framework allowed Barrick to present selectively edited surveillance footage and hearsay from coworkers to undermine a doctor’s professional medical assessment without obtaining its own medical evaluation. | high |
| 01 | Once Perez alleged a workplace injury, Barrick faced potential liability for worker’s compensation benefits, which increase insurance premiums and incur direct payouts that cut into corporate profit margins. This created a financial incentive to discredit his claim. | high |
| 02 | FMLA leave for a haul truck driver creates staffing gaps requiring Barrick to pay overtime to existing workers or hire temporary replacements. In high-stakes underground mining operations, scheduling disruptions add costs that corporations seek to minimize. | medium |
| 03 | Barrick policy requires employees to report all injuries and incidents immediately, yet Perez did not report the collision until the end of his shift hours later. The company used this delay as grounds to doubt the entire incident occurred, despite the subsequent medical certification. | medium |
| 04 | The company invested resources in hiring private investigators to conduct multi-day surveillance rather than paying for a second medical opinion or accepting the treating physician’s certification. This reveals a corporate preference for discrediting workers over validating medical claims through proper channels. | high |
| 05 | Barrick operates in a heavily capital-intensive industry where worker’s compensation claims, FMLA-protected wages, and insurance premiums represent controllable cost variables. The decision to aggressively investigate and terminate Perez reflects a profit-maximization strategy that treats injury claims as threats to the bottom line. | high |
| 06 | With a current market capitalization of 32.5 billion dollars, Barrick possesses vastly superior financial resources compared to individual workers like Perez. This power imbalance allows the corporation to outspend employees in legal battles and investigative efforts. | medium |
| 01 | Perez worked as an underground haul truck driver, operating heavy machinery in one of the most hazardous work environments. When he reported an injury from a collision with the mine wall, the company’s response was investigation and termination rather than support and accommodation. | high |
| 02 | The on-site emergency medical technician who examined Perez did not observe outward signs of injury, and Dr. Black found no abnormalities in X-rays, yet the doctor still diagnosed a chest wall contusion and muscle spasms based on Perez’s reported pain. The company dismissed this professional medical judgment entirely. | high |
| 03 | Barrick confronted Perez with hearsay evidence from an employee who claimed a friend of Perez said he was faking the injury to work on rental properties. The company relied on third-hand gossip to justify its suspicion rather than medical evidence. | high |
| 04 | When confronted with the investigator’s findings and employee reports, Perez responded that he had nothing to say. The company interpreted this silence as an admission rather than considering it might reflect an employee’s fear, confusion, or recognition of the power imbalance. | medium |
| 05 | The surveillance footage showed Perez performing activities like holding arms overhead and using power tools, but provided no medical context about whether these brief activities were consistent with his diagnosed condition of chest wall contusion and muscle spasms. The jury was asked to make medical determinations from video clips. | high |
| 06 | Perez lost his job, income, and likely his employer-provided health insurance at precisely the time he claimed to be recovering from a workplace injury. This created immediate financial hardship and potential barriers to continued medical treatment. | high |
| 07 | The legal battle required Perez to prove both that he had a serious health condition and that Barrick terminated him specifically for taking protected leave. This dual burden placed enormous evidentiary weight on an individual worker facing a multi-billion dollar corporation’s legal team. | high |
| 08 | The case sends a chilling message to other workers that reporting injuries, even with doctor’s certification, may result in surveillance, investigation, job loss, and protracted litigation with uncertain outcomes. This discourages legitimate injury reporting across the workforce. | high |
| 01 | Barrick never requested a recertification of Perez’s medical condition or obtained a second medical opinion as contemplated by FMLA regulations. Instead, it proceeded directly to hiring private investigators and building a termination case. | high |
| 02 | The company found no physical evidence that Perez’s truck had collided with the mine wall, but rather than investigating potential safety issues or equipment failures, it immediately assumed Perez was lying about the entire incident. | medium |
| 03 | Barrick relied on an email from an employee reporting hearsay from one of Perez’s friends as justification for its investigation. The company treated unverified gossip as credible grounds to doubt a licensed physician’s medical certification. | high |
| 04 | The private investigator’s surveillance captured three days of selective footage showing Perez engaging in various activities, but provided no medical analysis of whether these activities were consistent with his diagnosed condition or contradicted his doctor’s assessment. | high |
| 05 | The jury verdict in Barrick’s favor means the company faced no financial penalties, no requirement to reinstate Perez, and no acknowledgment of wrongdoing. The corporation successfully defended its termination decision and avoided all liability. | high |
| 06 | The appellate court’s ruling that employers need not present contrary medical evidence to challenge FMLA certifications creates a legal precedent that weakens protections for injured workers nationwide. Barrick’s legal victory establishes a blueprint for other employers to follow. | high |
| 07 | Despite allegations of FMLA interference and wrongful termination, Barrick maintained its position that Perez violated company policy by failing to properly report his injury and lying about its existence. The company framed itself as the victim of employee fraud rather than acknowledging any missteps in its handling of the situation. | medium |
| 01 | Underground mining is inherently dangerous work involving heavy machinery, confined spaces, and serious injury risks. When workers fear that reporting injuries will lead to surveillance and termination, they may continue working while hurt, creating additional safety hazards. | high |
| 02 | Dr. Black prescribed muscle relaxants and certified Perez for eighteen days off work based on his clinical judgment. The company’s decision to override this medical determination with surveillance footage undermines the role of healthcare providers in workplace injury assessment. | high |
| 03 | The case establishes that corporations can use non-medical evidence to convince juries that workers do not have serious health conditions, even when licensed physicians have certified otherwise. This precedent threatens the integrity of medical evaluations in FMLA cases. | high |
| 04 | Workers who observe colleagues being investigated, surveilled, and terminated after reporting injuries learn that the safest course is to hide injuries and work through pain. This creates a workplace culture where health problems go unreported and untreated. | high |
| 05 | The adversarial approach to worker injury claims prioritizes corporate suspicion over employee wellbeing. Rather than focusing on safety improvements or injury prevention, the company devoted resources to proving Perez was faking his condition. | medium |
| 06 | If Perez genuinely had a chest wall contusion and muscle spasms but was performing limited activities at home during recovery, the surveillance footage provided no medical context for whether such activities were harmful, therapeutic, or simply evidence of pain tolerance. The jury made medical judgments without medical expertise. | medium |
| 01 | Mining communities often depend heavily on a single large employer for jobs, tax revenue, and economic stability. When that employer demonstrates aggressive tactics against injured workers, community members face pressure to stay silent about workplace hazards to preserve employment. | high |
| 02 | Perez’s termination removed his income and likely his family’s health insurance at a time when he claimed to be recovering from injury. These cascading consequences affect not just the worker but spouses, children, and extended family members who depend on that income. | high |
| 03 | Other workers at Barrick’s mine witnessed the company’s response to Perez’s injury claim: hire investigators, gather surveillance, confront the worker, and terminate employment. This sends a clear message about what happens when employees assert FMLA rights. | high |
| 04 | Local businesses in mining communities depend on workers’ wages circulating through the economy. When workers are terminated and face financial hardship, the economic effects ripple through grocery stores, restaurants, and service providers. | medium |
| 05 | The legal battle consumed years of Perez’s life, from the 2019 filing of the lawsuit through the 2024 appellate decision. During this time, he faced unemployment, legal expenses, and uncertainty while Barrick continued operations with its $32.5 billion market capitalization intact. | medium |
| 01 | Barrick did not immediately accept Dr. Black’s medical certification despite having the option under FMLA regulations to request a second or third medical opinion at the company’s expense. Instead, it chose the path of private investigation and confrontation. | medium |
| 02 | The investigation involved three days of surveillance, compiling video evidence, and building a case against Perez before confronting him. This methodical approach suggests a deliberate strategy rather than an immediate response to new information. | medium |
| 03 | Perez filed his lawsuit in 2019, and the case was not decided on appeal until June 2024, representing approximately five years of litigation. During this extended period, Perez bore the costs and uncertainty while Barrick operated with full resources. | high |
| 04 | The case went through district court proceedings including a full jury trial, then appellate review before the Ninth Circuit Court of Appeals. Each stage required legal representation, court filings, and extended timelines that favor the party with greater resources. | medium |
| 05 | Corporate defendants in FMLA cases can exploit procedural rules and evidentiary standards to shift burdens onto injured workers. Perez had to prove both his medical condition and the employer’s retaliatory intent, creating multiple hurdles to overcome. | high |
| 01 | The Ninth Circuit’s ruling that employers need not present contrary medical evidence to challenge FMLA certifications creates a legal framework that privileges corporate suspicion over medical professional judgment. This weakens federal protections for workers who take medically necessary leave. | high |
| 02 | Barrick’s decision to hire private investigators rather than obtain second medical opinions reveals a corporate strategy focused on discrediting workers rather than validating medical claims through proper channels. This approach prioritizes cost control over employee welfare. | high |
| 03 | The case demonstrates the vast resource disparity between a $32.5 billion corporation and an individual worker. Barrick could afford private investigators, extensive legal representation through multiple law firms, and years of litigation, while Perez faced unemployment and uncertainty. | high |
| 04 | By prevailing at trial and on appeal, Barrick avoided any financial penalty, policy changes, or acknowledgment of wrongdoing. The legal system validated the company’s aggressive approach to challenging worker injury claims, potentially encouraging similar tactics industry-wide. | high |
| 05 | The surveillance, investigation, confrontation, and termination sequence creates a template that other employers can follow when they doubt worker injury claims. This pattern threatens to chill legitimate injury reporting across industries where workers fear similar treatment. | high |
| 06 | Workers in hazardous industries face an impossible choice: report injuries and risk investigation, surveillance, and termination, or hide injuries and continue working while hurt. The legal outcome in this case reinforces that the safest career move may be to suffer in silence. | high |
| 07 | The case illustrates how neoliberal capitalism’s emphasis on profit maximization, cost control, and deregulation creates structural incentives for corporations to aggressively challenge worker protections. Individual legal victories for employers accumulate into systemic erosion of labor rights. | high |
| 08 | Despite the FMLA’s purpose of protecting workers who need medical leave, the combination of permissive statutory language, corporate resources, and favorable court precedents means that asserting these rights carries substantial risk for workers while imposing minimal costs on employers who contest them. | high |
Timeline of Events
Direct Quotes from the Legal Record
“Agreeing with other circuits, the panel held that the Family and Medical Leave Act does not require an employer to present contrary medical evidence before contesting a doctor’s certification of a serious health condition.”
💡 This ruling allows employers to dismiss medical certifications without obtaining their own medical opinions, undermining healthcare provider judgments.
“In any case in which the employer has reason to doubt the validity of the certification under § 2613(a), the employer may require that the employee, at the employer’s expense, obtain the opinion of a second or third health care provider or seek recertifications on a reasonable basis.”
💡 The statute gives employers the option to get second opinions but does not require it, allowing them to choose surveillance over medical validation.
“Over the course of three days, the investigator captured video evidence of Perez engaging in various activities without visible signs of difficulty or discomfort, including driving through town, gambling at a casino, performing repair work at his rental property, repeatedly lifting and holding both arms over his head, and carrying and using a power drill and other tools and equipment.”
💡 The company used surveillance footage of selective activities to challenge a physician’s medical certification without medical expert analysis.
“An employee later emailed management that one of Perez’s friends told the employee that Perez is faking a work related injury in order to take time off to work on personal business (fixing rental properties).”
💡 Barrick relied on third-hand gossip as justification for its aggressive investigation rather than medical evidence.
“Although Barrick policy requires employees to report all injuries and incidents immediately, Perez did not report the collision until the end of his shift, hours later.”
💡 The company used the reporting delay to cast doubt on whether the injury occurred at all, despite subsequent medical certification.
“Dr. Black, who treated Perez, found no outward signs of injury, no abnormalities in Perez’s X-rays, and that Perez’s heart and lungs were functioning normally. Nevertheless, based on Perez’s explanation of the accident and his resulting pain, Dr. Black diagnosed Perez with a chest wall contusion and muscle spasms, prescribed him a muscle relaxant, and certified that he was to remain off work for five days, pending a follow-up appointment.”
💡 A licensed physician made a clinical diagnosis based on patient history and examination, which the employer then chose to reject without contrary medical evidence.
“When Perez returned from leave, Barrick confronted Perez with the employee’s report and investigator’s findings. Perez responded that he had nothing to say. Barrick then fired Perez after concluding that he had faked his injury and violated company policy.”
💡 The worker’s silence when confronted was interpreted as grounds for termination rather than a reasonable response to an intimidating corporate investigation.
“The jury returned a verdict for Barrick, finding that Perez had not shown by a preponderance of the evidence that he suffered a serious health condition preventing him from performing his job or that Barrick terminated his employment because he filed a worker’s compensation claim.”
💡 Despite a doctor’s certification, the jury sided with surveillance footage, placing the burden entirely on the injured worker to prove his condition.
“We do not read § 2613(c)(1) as requiring an employer to obtain a second opinion or else waive any future opportunity to contest the validity of the certification.”
💡 This precedent means employers can skip the medical review process and proceed directly to challenging certifications with non-medical evidence in court.
“The word ‘may’ is permissive. The plain language of the FMLA therefore merely provides an employer with the option to require a second or third opinion and seek recertification. It does not require an employer to provide contrary medical evidence if it doubts the validity of the original certification.”
💡 The court’s interpretation prioritizes employer discretion over medical professional judgment, weakening worker protections.
“The jury properly considered the non-medical evidence that Barrick offered at trial in support of its argument that Perez did not have a serious health condition within the meaning of the Act.”
💡 Laypeople on a jury were permitted to override a physician’s medical certification using surveillance footage and hearsay.
“The district court therefore did not err by failing to instruct the jury that only contrary medical evidence could defeat Perez’s doctor’s certification.”
💡 The appellate court validated the legal framework that allows employers to use any evidence type to challenge medical certifications.
“An employer may request recertification of a health care provider’s original certification for leave if the employer receives information that casts doubt upon the employee’s stated reason for the absence or the continuing validity of the certification.”
💡 This low bar for employer doubt, combined with permissive language about seeking medical opinions, creates wide latitude for challenging legitimate claims.
“All circuit courts to confront the issue have rejected Sims’s conclusion that an employer who requires a first certification from a physician is bound by those findings unless it seeks a second opinion.”
💡 Federal appellate courts nationwide have aligned to give employers maximum flexibility to challenge medical certifications without medical evidence.
“Because Perez claimed that he was still suffering severe pain from certain movements at the follow-up, Dr. Black certified Perez to remain off-work for another eleven days. Perez was approved to return to work eighteen days after the alleged accident, with no restrictions.”
💡 The physician’s clinical judgment about recovery timeline was disregarded in favor of surveillance footage showing brief activities during leave.
