ACOEM Reports Long COVID Linked to Work Productivity Loss

At two years after diagnosis of COVID-19, employees who experience long COVID symptoms have substantially reduced work productivity, reports a study in the August issue of the Journal of Occupational and Environmental Medicine.

Led by Hiten Naik, MD, SM, of The University of British Columbia and the Post-COVID-19 Interdisciplinary Clinical Care Network, Vancouver, the online survey study included 908 employed patients diagnosed with COVID-19 between March 2020 and May 2021. Of these, 165 patients were classified as having long COVID, defined as continued symptoms three months after an initial positive COVID-19 test. Work productivity loss and work performance impairment were assessed using validated questionnaires.

About 75% of participants with ongoing long COVID symptoms reported any productivity loss within the last three months, compared to 47% of those without long COVID. After adjustment for other characteristics, employees in the long COVID group were about three times more likely to report lost productivity.

Average paid productivity loss over three months was about 62 hours, including 33 hours of absenteeism and 29 hours of presenteeism (decreased productivity at work). Long COVID was also associated with high unpaid productivity loss, including activities such as caregiving and household chores: about 37 hours, on average.

About 73% of participants with long COVID reported impaired work performance within the past week, compared to 39% of those without long COVID symptoms. On adjusted analysis, employees with long COVID were four times more likely to have work performance impairment. Based on average hourly wage, the economic impact of total productivity loss was estimated at nearly $14,000 CAD over a year.

Long COVID has been described as a “global public health crisis,” affecting over 400 million people worldwide. Although studies have shown that long COVID can impair health and occupational functioning, the overall impact on work productivity loss has been unclear.

Long COVID is “associated with substantial productivity loss, even two years after the onset of SARS-CoV-2 infection and even in individuals who have returned to work,” Dr. Naik and coauthors conclude. “Clinicians, health systems, and employers should understand that long COVID can have long-lasting impacts on occupational functioning and requires long-term support.”

Walgreens Agrees to Continue Providing Essential Pharmacy Services

On March 6, 2025, Walgreens announced that it agreed to be acquired by private equity firm, Sycamore. The proposed transaction, which involves over 450 California Walgreens stores. Howevever a settlement was reached under Assembly Bill 853 (AB 853), which requires notice and review by the Attorney General of transactions involving retail pharmacies and grocery stores in order to assess impact on access and labor. AB 853 was authored by former Assemblymember Brian Maienschein (D-San Diego) and went into effect on October 8, 2023. The settlement is subject to court approval.

Walgreens is the last nationwide and statewide independent pharmacy chain – that is, a chain not owned by one of the Big Three Pharmacy Benefit Managers (PBMs), which are CVS Caremark, Optum Rx, and Express Scripts. The proposed transaction between Walgreens and Sycamore includes, but is not limited to, the following Walgreens stores in California: six in Bakersfield, 11 in Fresno, five in Huntington Beach, 13 in Los Angeles, eight in Modesto, five in Riverside, seven in Sacramento, seven in San Diego, 26 in San Francisco, 10 in San Jose, and seven in Stockton.

The California Attorney General announced a settlement with Walgreens Co. and its succeeding owner, Sycamore Partners Management, L.P. (Sycamore), that would operate as an injunction and protect competition, patients, and pharmacy-related workers.

Under the settlement, Walgreens and Sycamore agree to the following conditions for the next seven years:

– – Use best efforts to maintain all California Walgreens stores remaining as of the date of the agreement, as well as all required licenses.
– – Provide 90-day notice of sale or closure of any remaining Walgreens stores.
– – Prohibition from reselling any of the Walgreens stores in California to any of the Big Three PBMs.
– – Prohibition from using any dividend recapitalization or other distribution of profits where such a dividend recapitalization or other distribution of profits would reasonably be likely to materially impair the operations of Walgreens.
– – Use best efforts to continue participation in Medi-Cal and Medicare.
– – Use best efforts to provide financial assistance to patients.
– – Ensure best efforts regarding compliance with state staffing levels.
– – Maintain a hiring list for all employees from stores that close going forward for preferential hiring at other Walgreens stores.
– – Use commercially reasonable efforts to pay retirement contributions if collective bargaining agreements require such payments.
– – Use commercially reasonable efforts to abstain from contesting unemployment for individuals who are laid off as a result of the sale or closure of Walgreens stores if no nearby Walgreens store offers employment.
– – Use commercially reasonable efforts to bargain with any unions in good faith.
– – Comply with nondiscrimination rules in the provision of healthcare services.

This settlement is the second reached by the California Attorney General under AB 853. The first settlement was with Rite Aid and was announced on August 19, 2024. In addition, on April 14, 2025, the California Attorney General joined a bipartisan coalition of 39 attorneys general in urging the leaders of the U.S. House of Representatives and U.S. Senate to enact a law that prohibits PBMs, their parent companies, or affiliates from owning or operating pharmacies.

Created in the late 1960s to process claims for drug companies, PBMs were supposed to help consumers access low-cost pharmaceutical care through negotiated volume-pricing discounts, generic substitution, manufacturer rebates, and other tools. However, PBMs have overtaken the market and now wield outsized power to reap massive profits at the expense of consumers and local community pharmacies.

Owner Sets Fire to Fresno Restaurant For Insurance Fraud

Well-known Fresno restaurant owner Robert “Bobby” Salazar, 63, has been arrested on a federal complaint for arson of commercial property and arson in furtherance of a felony for directing a motorcycle gang member to set fire to an underperforming restaurant property, U.S. Attorney Eric Grant announced.

Salazar pleaded not guilty Thursday during a federal court appearance. Prosecutors also filed additional charges after investigators discovered five firearms at his home, including four with serial numbers removed and one ghost gun.

According to court documents, on April 2, 2024, a fire broke out at the vacant Bobby Salazar’s restaurant on Blackstone Avenue in Fresno. Fire investigators determined that the cause of the fire was arson, with partially burned gas cans located inside the restaurant and extensive fire damage to the interior:

According to court documents, agents learned that the person who set the fire was the president of the local Screamin’ Demons Motorcycle Club. Salazar allegedly hired the motorcycle gang member to start the fire and then claimed to his insurance company that he had nothing to do with the arson. He was ultimately paid out at least $980,739 for his insurance claim.

If convicted, Salazar faces a mandatory minimum of five years in prison and maximum statutory penalty of 20 years in prison for commercial arson, as well as 10 years in prison mandatorily consecutive for arson in furtherance of a felony. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables. The charges are only allegations; the defendant is presumed innocent until and unless proven guilty beyond a reasonable doubt.

This case is the product of an investigation by the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Fresno Fire Department, with assistance from the Fresno Police Department, the Fresno County Sheriff’s Department, and the Federal Bureau of Investigation. Assistant U.S. Attorneys Robert L. Veneman-Hughes and Brittany M. Gunter are prosecuting the case.

Burbank Blood Test Lab Owner Pleads Guilty in Fraud Case

A Burbank man has pleaded guilty to evading the payment of more than $11.2 million in federal taxes by using a shill to illegally collect Medicare reimbursement payments made to his blood-testing company, and to fraudulently obtaining nearly $100,000 in taxpayer-funded COVID-19 business relief, the Justice Department announced today.

Armen Muradyan, 60, pleaded guilty to one count of conspiracy to commit health care fraud, one count of wire fraud, and one count of tax evasion.

According to his plea agreement, Muradyan owned and operated a Burbank-based blood testing laboratory called Genex Laboratories Inc. Medicare and bank records show that Medicare paid millions of dollars in reimbursements to Genex for blood testing. The reimbursements were wired to bank accounts in the name of an individual identified in court documents as “L.S.” – Muradyan’s long-time friend to whom Muradyan had offered to pay $2,000 per month to pretend to be Genex’s owner.

Muradyan told L.S. that he needed him to submit Medicare enrollment papers to Medicare on Genex’s behalf because Medicare had banned Muradyan from submitting claims.

L.S. and Muradyan opened bank accounts for Genex in L.S.’s name, but which Muradyan controlled. L.S. neither owned nor operated Genex and visited the company’s Burbank office to collect his $2,000 monthly payment and to sometimes sign documents at Muradyan’s direction. Muradyan used the proceeds from the health care fraud conspiracy to pay the mortgage on a property he owned.

For the tax years of 2015 through 2020, Muradyan instructed L.S. to report Genex’s financial activity on L.S.’s personal income tax returns using documents that L.S. provided to his own tax preparer. The documents purportedly showed that Genex had minimal net profit or was operating at a loss, meaning the company had little or no income tax liability.

For the same period, Muradyan submitted income tax returns that reported none of Genex’s financial activity as his own and that he averaged an income of $40,000 per year. In fact, Muradyan personally received and used millions of dollars in Medicare reimbursements to support his own expensive lifestyle. Muradyan also did not file tax returns for the years 2021 through 2023.

In total, Muradyan’s unreported federal taxable income was approximately $23,915,762, resulting in a total federal income tax due and owing by him of approximately $11,236,357.

In July 2020, Muradyan wired a false and fraudulent application for an Economic Injury Disaster Loan (EIDL) that was funded by federal taxpayers. On the application, Muradyan falsely stated that GenMed employed multiple people and generated $800,000 in income for the year 2019. In fact, Muradyan knew GenMed employed no one and generated zero income for that year. The U.S. Small Business Administration (SBA) wired $99,900 to a bank account Muradyan controlled. He then used the money for personal expenses not permitted under the terms of the EIDL. Muradyan admitted he acted with the intent to deceive and cheat the SBA.

United States District Judge John A. Kronstadt scheduled a December 11 sentencing hearing, at which time Muradyan will face a statutory maximum sentence of 20 years in federal prison for the wire fraud count, up to 10 years in federal prison for the health care fraud conspiracy count, and up to five years in federal prison for the tax evasion count. Muradyan remains free on $2.6 million bond.

IRS Criminal Investigation, the FBI, and the United States Department of Health and Human Services Office of Inspector General investigated this matter.

Assistant United States Attorney Mark Aveis of the Major Frauds Section and Trial Attorney Mahana K. Weidler of the Department of Justice’s Tax Division are prosecuting this case.

Jury Finds L.A. Personal Injury Lawyer Guilty of Money Laundering

A Los Angeles-area lawyer was found guilty by a jury of receiving a $2.1 million bribe while serving as an officer of Nigeria’s state-owned oil company in connection with negotiating favorable drilling rights for a subsidiary of a Chinese state-owned oil company.

Paulinus Iheanacho Okoronkwo, 58, a.k.a. “Pollie,” of Valencia, who practiced immigration, family, and personal injury law out of an office in Koreatown, was found guilty of three counts of transactional money laundering, one count of tax evasion, and one count of obstruction of justice.

According to evidence presented at a four-day trial, Okoronkwo, who is a dual citizen of the United States and Nigeria, was a foreign official who served as the general manager of the upstream division of the Nigerian National Petroleum Corp. (NNPC), a state-owned company through which Nigeria’s government developed that nation’s fossil fuel and natural gas reserves, including through partnerships with foreign oil companies. In this role, Okoronkwo owed a fiduciary duty to the Nigerian government and was a public official.

In October 2015, Addax Petroleum, a Switzerland-based subsidiary of Sinopec, a Chinese state-owned petroleum, gas, and petrochemical conglomerate, wired a payment of $2,105,263 to an Interest on Lawyers’ Trust Account (IOLTA) in the name of Okoronkwo’s Los Angeles law firm, purportedly for his work as a consultant who negotiated and completed a settlement agreement with the NNPC with respect to Addax’s drilling rights in Nigeria. According to the indictment, Addax calculated that it stood to lose billions of dollars if its favorable drilling rights were not secured.

The engagement letter that Addax signed that month with Okoronkwo’s law office – with a fake address in Lagos, Nigeria – was a ruse intended to conceal the fact that its payment to Okoronkwo was a bribe in exchange for his influence in securing more favorable financial terms relating to its crude oil drilling in Nigeria.

To conceal the illegal bribery scheme, Addax falsely characterized the $2.1 million payment as a payment for legal services, lied to an auditor about the payment, and fired executives who questioned the payment’s propriety. To create the false impression that the bribe payment constituted client funds, Okoronkwo received the payment in his law firm’s IOLTA.

In November 2017, Okoronkwo used $983,200 of the illegally obtained funds to make a down payment on a house in Valencia.

Okoronkwo omitted the $2.1 million bribe payment from his 2015 federal income tax return. He also obstructed justice in June 2022 when he lied to federal investigators when he told them he did not use any of the $2.1 million to purchase a house and that the money represented client funds rather than income to his law office.

United States District Judge John F. Walter scheduled a December 1 sentencing hearing, at which time Okoronkwo will face a statutory maximum sentence of 10 years in federal prison for each illegal monetary transactions count, up to 10 years in federal prison for the obstruction of justice count, and up to five years in federal prison for the tax evasion count. Okoronkwo is free on $50,000 bond.

The FBI and IRS Criminal Investigation investigated this matter. The Justice Department’s Office of International Affairs provided assistance.

Assistant United States Attorneys Alexander B. Schwab, Deputy Chief of the Criminal Division, Nisha Chandran of the Major Frauds Section, and Alexander Su of the Asset Forfeiture and Recovery Section are prosecuting this case.

Tesla HR Execs’ Lawsuit Blames HR Manager for Retaliation

Former Tesla HR execs Linda Peloquin, Adam Chow, Tiara Paulino, Sharnique Martin, Gregory Vass and Ozell Murray just filed a lawsuit against Tesla Inc., in the United States District Court for the Northern District of California Case 3:25-cv-06690-AMO. The lawsuit concerns the automaker’s Fremont, California, facility that has been at the center of several previous discrimination lawsuits.

These former Tesla HR professionals alleged that they were either fired or effectively forced to resign after attempting to surface other employees’ race discrimination and retaliation complaints at the company’s Fremont, California, plant.  

According to the Peloquin complaint, one of Tesla’s HR managers, Nicole Burgers, was a “common denominator” in the various claims made by the plaintiffs. They alleged that the manager, the overall HR manager for the entire Fremont facility, “had an irrational fixation on fostering the delusion that the environment and culture at Tesla is one of tolerance and innovation, rather than racism and retaliation.”

Allegations continue to say that “Much of Tesla’s workplace toxicity stems from its rapid sales growth and manufacturing demand, and the breakneck pace at which it hired employees to work in its plants and overall operation. Since its introduction in 2020, Tesla’s “Model Y,” for instance, has become the Company’s top-selling vehicle line – and, by most estimates, one of the top-selling electric vehicles in the world. Thus, there was, and remains, constant pressure to keep the Model Y’s sales trajectory high.”

“Yet, as a consequence of this desire to produce vehicles at such a rapid pace, the Company has failed to cultivate a healthy working environment at the Fremont facility, and instead fostered one that is beset with racism, sexism, cronyism, and outright physical violence.”

Plaintiffs claim “even employees that had been terminated for instances of workplace violence were loopholed back in via temp agencies. That meant, then, that oftentimes the employee who had been previously victimized had to actually resume working with their attacker and tormentor.”

“In fact, that Senior Security Manager himself was attacked and suffered a serious injury when he attempted to stop a loopholed employee – one who had been returned to work after being terminated for cause – after that employee came back aboard and attacked another worker.”

At some point plaintiffs allege that Tesla “turned its ire on the HR professionals that had merely investigated and substantiated the bases of the complaints. So, oddly, in most instances it was the HR official that wound up being penalized and pushed out for substantiating the alleged wrongdoing rather than the wrongdoer themselves. Consequently, a dizzying number of HR professionals – the Plaintiffs here: Peloquin, Chow, Paulino, Martin, and Vass, among them – have either been outright fired for substantiating complaints of discrimination and retaliation, or resigned because they saw a termination coming and did not want that type of disciplinary stain on their job history.

Details of the complaint allege “A common denominator in many of these terminations is a HR Manager named Nicole Burgers. By all accounts, Burgers has had an irrational fixation on fostering the delusion that the environment and culture at Tesla is one of tolerance and innovation, rather than racism and retaliation. By all accounts, given that Burgers was the overall HR manager for the entire Fremont facility, she believed that she would be held accountable for further instances of racism and misconduct at the Fremont location – particularly in light of the pending State, Federal, and private litigation against the Company. Thus, rather than undertake to change the culture and environment that fostered those types of instances of racism, Burgers instead undertook to weed out the HR professionals beneath her that merely investigated and substantiated the occurrence of that type of depravity.”

Page 24 of the 159 page complaint continues to provide details by writing “Karen Draper was one of the first dominos to fall in what became a long line of retaliatory terminations by Burgers and her Texas-based counterparts – Allie Arebalo, Bert Somsin, Jenifer Romero, and Leah Allen – or, instances where other HR professionals simply resigned under protest because they knew Burgers had begun to target them.

Fresno Superior Court Judge Charged With Multiple Felonies

Adolfo M. Corona was a judge of the Superior Court of Fresno County in California. He assumed office in 2003. He left office on May 1, 2024. Corona was appointed by Gov. Gray Davis in 2003. His legal career included working as an attorney at Dowling Aaron & Keeler Inc. in Fresno from 1986 to 2003 and serving as a judge pro tem for the Fresno County Superior Court from 1992 to 2003. He was also a member of the Central Valley Chapter of La Raza Lawyers Association. At the time of his retirement, he was presiding over juvenile court cases.

State charges were first filed against Corona in September 2024 following a state grand jury indictment by the Fresno County District Attorney. Prosecutors charged him on one count of felony sexual penetration by force, fear, or duress and one count of misdemeanor sexual battery, stemming from an alleged assault on a court employee on March 14, 2024, at the Fresno County Superior Court. He pleaded not guilty, was released on $70,000 bail, and is represented by attorneys Michael Aed and Margarita Martinez-Baly.

The two renowned local defense attorneys have represented the likes of Assemblymember Joaquin Arambula. Aed reportedly would not answer questions about the timing of the judge’s resignation, weeks after the alleged incident. “He is entitled to counsel of his choice. This case came out of the blue without any pre-warning. He made certain decisions at the beginning of the case. He expects a vigorous and complete defense, and we intend to give him that,” Aed reportedly said.

Now in August 2025, the U.S. Justice Department announced that a federal grand jury in Fresno returned a five-count indictment charging 66 year old Corona with federal offenses for sexually assaulting a court employee (Victim 1), making false statements to cover up the assault, and with obstructing the investigation into allegations that he sexually assaulted another court employee (Victim 2) in his chambers.

Assistant Attorney General Harmeet K. Dhillon of the Justice Department’s Civil Rights Division, U.S. Attorney Eric Grant of the Eastern District of California, and Special Agent in Charge Siddhartha Patel of the FBI Sacramento Field Office made the announcement regarding the new federal case.

The indictment alleges that on March 14, 2024, Corona, while serving as a California Superior Court Judge, led Victim 1 into a courthouse stairwell where he sexually assaulted her. The indictment further alleges that Corona, during separate interviews with the FBI and court administrators, made false statements about the circumstances of his assault on Victim 1.

Additionally, the indictment alleges that Corona obstructed the investigation into allegations that he sexually assaulted Victim 2. Corona was alone with Victim 2 in his chambers for approximately two hours on Dec. 5, 2023, and she was later found alone in the judge’s chambers after being passed out. The indictment charges that Corona falsely told the FBI that he left Victim 2 alone in his chambers while he drove to pick up a motorcycle. Corona allegedly attempted to persuade a motorcycle dealership employee to change company records to falsely reflect that he had picked up his motorcycle in order to corroborate his alibi.

If convicted, Corona faces a maximum sentence of 40 years in prison on the sexual assault charge and 20 years on each of the obstruction charges. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables. The charges are only allegations; the defendant is presumed innocent until and unless proven guilty beyond a reasonable doubt.

This case is the product of an investigation by the Federal Bureau of Investigation and the Fresno County Sheriff’s Office. Assistant U.S. Attorney Karen Escobar for the Eastern District of California and Special Litigation Counsel Michael J. Songer of the Civil Rights Division’s Criminal Section are prosecuting the case.

Anyone with information about this investigation is encouraged to contact their local FBI office, call 1-800-CALL-FBI (1-800-225-5324), or submit a tip to tips.fbi.gov.

Musk’s X Reaches Tentative Settlement $500M Class Action

Elon Musk’s social media company, X Corp, has reached a tentative settlement in a lawsuit filed by former employees who claimed they were owed $500 million in severance pay.

The lawsuit, filed as a proposed class action in the U.S. District Court for the Northern District of California (Case No. 23-03461, McMillian et al. v. Musk et al.), was initiated in July 2023 by former Twitter employees Courtney McMillian (former head of total rewards, overseeing employee benefits) and Ronald Cooper (former operations manager).

They alleged that Twitter’s 2019 severance plan, established under the company’s previous ownership, entitled laid-off employees to substantial payouts: two months of base pay plus one week for each year of service for most workers, and up to six months for senior employees like McMillian.

Following Elon Musk’s $44 billion acquisition of Twitter in October 2022 and the subsequent rebranding to X, approximately 6,000 employees were terminated as part of cost-cutting measures. The plaintiffs claimed that X Corp. violated this plan by offering at most one month of severance pay, with many receiving nothing, resulting in an estimated $500 million in owed benefits.

On July 9, 2024, U.S. District Judge Trina L. Thompson dismissed the case without prejudice. The core of her ruling centered on the inapplicability of the federal Employee Retirement Income Security Act (ERISA), which governs employee benefit plans and provides federal jurisdiction for such disputes. Judge Thompson determined that Twitter’s severance arrangement did not qualify as an ERISA-governed plan because it lacked an “ongoing administrative scheme.

However, Judge Thompson allowed the plaintiffs the opportunity to amend their complaint to pursue alternative claims not reliant on ERISA, such as potential state law breach-of-contract allegations.

The plaintiffs appealed the dismissal to the U.S. Court of Appeals for the Ninth Circuit (Case No. 24-5045, McMillian v. Musk) shortly after the district court’s decision. In their appeal, the former employees argued that Twitter’s severance policy did indeed qualify as an ERISA plan because it involved ongoing benefit payments, even if administered without individualized discretion. They received support from the U.S. Department of Labor, which filed an amicus brief endorsing this view, emphasizing that ERISA coverage applies to plans paying benefits on a continuing basis regardless of administrative complexity.

In response, Musk and X Corp. filed a brief on January 9, 2025, urging the Ninth Circuit to affirm the dismissal. Their key arguments included:

– – No formal ERISA plan existed, as the employees failed to produce official plan documents (e.g., summary plan descriptions) or evidence of widespread communications to workers about the severance terms prior to Musk’s acquisition.
– – References to a “severance matrix” (a confidential document allegedly taken by McMillian) and general corporate statements at most indicated offers of simple lump-sum payments, which do not constitute an ERISA-governed scheme requiring ongoing administration.
– – This lack of a qualifying plan was “fatal” to the class action, as it undermined the basis for federal jurisdiction.

Oral arguments were scheduled for September 17, 2025, in San Francisco.

However, as of August 21, 2025, the parties reached a tentative settlement agreement, the financial terms of which were not disclosed. In a joint court filing, both sides requested a postponement of the hearing to finalize the deal, which would resolve the class action and compensate the affected former employees. The Ninth Circuit granted the delay on August 22, 2025, effectively pausing the appeal process. This settlement does not impact other ongoing related lawsuits, such as those in Delaware and California courts involving different claims or plaintiffs.

In summary, the appeal remains unresolved on the merits due to the impending settlement, marking a potential end to this specific dispute without a full appellate ruling on the ERISA question.

Other related lawsuits, including one by former executives like ex-CEO Parag Agrawal, remain pending. This settlement aims to resolve the dispute over severance pay for the affected former employees.

Group Studies Ethical & Social Risks of Exoskeleton Use for Safety

Construction continues to be one of the most dangerous industries, with workers constantly exposed to physically demanding and repetitive activities. Exoskeletons are emerging as ergonomic interventions that amplify human strength and agility while reducing muscle fatigue and discomfort. However, like any robotic technology, exoskeletons may have unintended consequences.

While studies have examined the health and safety risks of exoskeletons in construction, there is a significant gap in the literature regarding their ethical and social risks. Issues related to privacy concerns, exoskeletons’ design, and discrimination, among many others, are housed in the ethical risks, and social risks often include questions regarding exoskeletons’ affordability, accessibility and impact on social identity and communication, among others.

A new study just published by The Center for Construction Research and Training addresses that gap by investigating the ethical and social risks associated with exoskeleton use in construction, assessing their impact on workers’ health and safety and exploring how they can be designed to minimize these risks. This study further developed a comprehensive and practical worker-centric guide aimed at advancing the safe and ethical implementation of exoskeletons in the construction industry.

This research leverages a systematic literature review, a Delphi technique (consisting of three rounds of surveys), and a focus group discussion to achieve the research objectives. The study developed a practical, worker-centric guide that examines exoskeleton preferences for construction trades, ethical and social risks of exoskeletons, the impacts of these risks on construction workers’ health and safety, the impact of these risks on the implementation of exoskeletons in the construction industry, and strategies to mitigate these identified ethical and social risks. The study further highlights barriers to implementing the identified strategies.

1. Ethical and Social Risks: A total of 34 ethical and social risks were identified from the literature review. Out of the 34, 18 were verified by experts in the construction industry and used in this study. These risks are categorized under design, autonomy, dehumanization, stigmatization, vulnerability, affordability, and accessibility.
2. Risk Criticality: Experts rated the identified risks on a Likert scale of 1 to 5 (with 1 being not critical, 2 less critical, 3 moderately critical, 4 very critical, and 5 extremely critical). Results show inaccessibility and unaffordability are examples of Very Critical risks, and stigmatization and loss of identity are examples of Less Critical risks.
3. Exoskeleton Suitability: Passive exoskeletons are suitable for repetitive overhead work and awkward postures, while active exoskeletons are better for heavy lifting. Back-support exoskeletons are most suitable for trades such as plumbers and carpenters, while full-body exoskeletons suit laborers.
4. Risk Impact on Workers’ Health and Safety: The findings revealed that ethical and social risks related to design, autonomy, privacy, unauthorized access, dependency, exoskeleton weight, and overdependence pose significant health and safety concerns to workers.
5. Mitigating Strategies: Seventy strategies to mitigate identified ethical and social risks were proposed and evaluated.
6. Barriers to proposed strategies: Fifteen barriers to effective risk mitigation were identified.
7. Worker-Centric Guide: A comprehensive guide was developed to facilitate the implementation of exoskeletons such that the ethical and social risks are minimized.
