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.

HIGH SEVERITY
TL;DR

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

⚠️
Core Allegations
What the worker claimed happened · 8 points
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

Regulatory Failures
How the legal system enabled the employer’s tactics · 6 points
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
💰
Profit Over People
The corporate calculus behind challenging worker injuries · 6 points
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

Worker Exploitation
The vulnerable position of injured employees · 8 points
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

Corporate Accountability Failures
How Barrick avoided consequences · 7 points
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

Public Health and Safety
Broader implications for workplace injury reporting · 6 points
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

Community Impact
Effects on mining communities and workers · 5 points
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
Exploiting Delay
The timeline of investigation and litigation · 5 points
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
📊
The Bottom Line
What this case reveals about corporate power · 8 points
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

Direct Quotes from the Legal Record

QUOTE 1 FMLA does not require contrary medical evidence regulatory
“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.

QUOTE 2 Employer’s permissive right to seek second opinions regulatory
“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.

QUOTE 3 Private investigator surveillance findings allegations
“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.

QUOTE 4 Employee hearsay used as grounds for investigation allegations
“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.

QUOTE 5 Company policy on immediate injury reporting allegations
“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.

QUOTE 6 Medical findings despite lack of visible injury allegations
“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.

QUOTE 7 Confrontation and termination allegations
“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.

QUOTE 8 Jury verdict requirements accountability
“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.

QUOTE 9 Rejection of medical certification binding rule regulatory
“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.

QUOTE 10 Plain language statutory interpretation regulatory
“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.

QUOTE 11 Jury consideration of non-medical evidence regulatory
“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.

QUOTE 12 No error in jury instructions regulatory
“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.

QUOTE 13 Reason to doubt certification standard regulatory
“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.

QUOTE 14 Circuit agreement on employer latitude regulatory
“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.

QUOTE 15 Extended medical leave certification allegations
“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.
