Electrocutions, Intimidation and Wage Theft Haunt Europe’s Data Center Workers

A five-month investigation by Investigate Europe in partnership with Tech Policy Press and media partners in eight countries reveals the harsh realities facing some working on the continent's vast AI infrastructure developments.

Sandu Dumitrescu* checked his watch. He was winding down the last 15 minutes of his shift at the Google data center site in Saint-Ghislain, Belgium, in March, when the call came in. He had just finished performing electrical checks on the site’s hall fans when his manager communicated a final request: could he run two quick tests right before he left? The 34-year-old electrical tester says he had to make a decision: he had already worked almost 10 hours. Yet in the highly pressurized environment of GBL-6, Google’s sixth data center in the vast €5 billion campus, such last-minute requests were normal.

“I had no choice,” Sandu says. “People have been fired after saying no.” He believed his Estonian-based supervisors on the Google site, where Irish company Dornan Engineering is the main electrical subcontractor, would not take a refusal well. Relying on his week-by-week contract and with hopes to call his wife and young son back in Romania that night, he resigned himself to finish the job.

The task was one he had done many times before and involved a series of tests measuring the safety and integrity of the electrical wiring. It should have taken about an hour. Sandu says the request came to him verbally, via an intermediary. A protective suit was locked away in an equipment room. The trip would have added another 15 minutes to the job, he says, and people were waiting. In the rush, Sandu decided not to retrieve the suit.

Once in the voltage room, Sandu says the managers confirmed the lines had been de-energized. In the first round, everything went as planned. Then, on the second test, while holding insulated tongs, he linked the cables. But this time, the lines were live.

The blast was immediate and catastrophic. In milliseconds, 400 volts and 12,000 amps hit Sandu’s face and across the right side of his body. A colleague who was down below the platform and witnessed the incident told Investigate Europe that he “heard a loud bang, saw a lot of smoke, and saw [Sandu] screaming in pain.”

“I went completely blind,” Sandu recalls. “I told the managers three times that I could not see.” But no managers answered, he claims. According to the witness who called for help, untangling Sandu from his harness in a mass of blackened flesh, the managers had run off, while Sandu writhed in pain on the ground.

Workers rushed to carry Sandu to an ambulance. When doctors received him in the Grand Hôpital de Charleroi, he was placed in an induced coma for five days.

Hospital records seen by Investigate Europe show that the arc flash electrocution had burned 12 percent of Sandu’s body, with second-degree burns to the face and neck as well as third-degree burns across his right shoulder and fingers. Photographs show scorched ears and swollen raw lips, with his arm a mess of hematoma and clotted skin.

When Sandu woke in the intensive care unit a week later after surgery, his wife was at his bedside. He says his entire body felt like a “white-hot blister…. It was so much pain. The human heart cannot comprehend it,” he recalls.

Two days after waking from his coma, the regional director of Google, along with a representative from Dornan and his Dutch recruitment agency, Wanted, came to visit. Sandu says that while he lay bandaged in the hospital bed, Google and Dornan each took a statement from him about the accident. The Google director told him he was lucky to be alive.

Sandu’s electrocution is both brutal and harrowing. Yet to date, no fines or sanctions are known to have been issued. Belgium’s federal labor inspectorate closed its investigation into the accident at the end of October and found no wrongdoing. Sandu says, however, that he was never interviewed directly by the labor authorities.

Despite repeated formal requests for his accident report from Wanted and Google, he has yet to receive it.

A month after his accident, the recruiter messaged Sandu to see how he was. They then asked: “[The company] is recruiting more testers (perhaps you know people?).”

A Google spokesperson told Investigate Europe: “Our supplier code of conduct and contracts require all suppliers to comply with local labor laws and uphold safe, healthy working conditions. We maintain active dialogue with union leaders and trade groups, and are committed to providing transparent information about our workplace."

A Wanted spokesperson said: “As an employer, we can, will and should be held accountable by the proper authorities. Although we agree that freedom of speech and press is a great asset, we cannot comment on the content besides the fact that your statements or claims are not correct.”

A five-month investigation led by Investigate Europe with media partners in eight countries into working conditions on data center sites across Sweden, Norway, Belgium and the Netherlands reveals that Sandu’s case is far from unique.

In extensive interviews with migrant workers at flagship sites where large US tech companies are operating, reporters found evidence of debilitating injuries, squalid living conditions, an unreported infectious outbreak, unpaid wages and exploitative employment practices.

Workers at one major Microsoft project described a culture of fear and intimidation where construction managers “rule on mental terror“. The testimonies are supported by dozens of health records, pay slips, phone messages, photographs and videos shared with reporters.

The investigation found a recurring pattern where tech companies and their many Irish construction partners embed US-style working practices, often in defiance of national working norms.

In Italy, Denmark, Finland, Sweden, Belgium, the Netherlands and Norway unions told reporters they had difficulty accessing certain sites to speak with workers and document conditions. One union representative in Denmark said some sites are “more closed than a state prison.”

The European data center industry is experiencing an infrastructure surge the continent has not seen in decades, dispatching tens of thousands of migrant workers to make its vision of tech sovereignty a reality.

A data center construction site can contain up to 2,000 workers and dozens of contractors, with up to a quarter of a million people working on sites across Europe every day.

The industry is one of big budgets and even bigger secrecy. Construction firms are often required to keep their tech clients secret, while contractors and intermediaries are also typically hidden from view.

At the same time, construction continues to rank as the most dangerous economic sector in the European Union. According to the latest Eurostat data, the sector recorded 776 deaths in 2024, representing nearly a quarter of all fatal workplace accidents in Europe.

By 2030, the industry is forecasting €100 billion of investments into European data centers. With over 2,300 facilities rapidly altering the physical and energy landscape of Europe, and hundreds more planned or in construction, the industry’s priorities appear abundantly clear: where to build, how fast to build, and which companies are prepared to build under budget.

‘Thank you for working safely’

“I wake up at two in the morning, and I can hear rats eating, moving in the walls. This house is full of rats. When I put pizza in the oven, they are running in the walls near me,” says Adrian*, a 45-year-old construction worker on a Microsoft data center site near Gävle in Sweden.

A video Adrian shared with Investigate Europe shows a large rat scurrying across a hallway and into an electrical storage room. In a string of text messages sent in August, Adrian begs the housing manager to get rid of them. The reply comes back: “Brother, I understand. But I have to wait for these other companies to come in and remove them, I can’t come in alone and just pull them out of the walls…”

If you head northwest out of Gävle, a town two hours from Stockholm, past timber-framed cottages and dense pine forests, a sign points you to a smooth road rolled out specifically for Microsoft. The remote clearing is part of a 130-hectare, 33.7 billion Swedish kronor (€3 billion) expansion plan started in June 2024 to scale up Microsoft’s AI data center infrastructure in the country.

Signs for Collen Construction line the drive, their banners draped across the large metal perimeter. Collen is among many Irish contractors overseeing data center build-outs across Europe. Hired by big tech clients to deliver projects on a strict timeline, these years-long projects manage a syndicate of other firms.

In the distance, beyond the security fencing, an airport-sized building looms, reflectionless and inscrutable. In the foreground, a bright red turnstile entryway welcomes workers in white lettering: ‘Thank You for Working Safely’.

One of Collen’s subcontractors, the Irish-owned construction company Benbau, employs hundreds of workers across Europe, including in Sweden, to work in areas such as site management, concrete and carpentry.

The workers are housed 20 minutes off-site in modular housing managed by Benbau.

For months, there has been a growing sense of outrage among Adrian and his colleagues working for Benbau on the Microsoft site. They have reported vermin infestations, broken ventilation systems, and lack of heating during the sub-zero Swedish winters, but they claim the problems remain unresolved.

One 50-year-old Romanian worker, who is diabetic, shared images of his toes that had lost circulation after wearing what he claims were poor work boots issued by Benbau. He had to have his toe amputated several months ago.

Adrian says it has been months since he first reported the rat infestation, and the rodents have multiplied inside the 40-room modular housing unit. Another video appears to take the viewer down a narrow hallway into a shared kitchen and lounge, where surveillance cameras are mounted in the corners. Inside the crowded housing, workers say the stress runs high: 24 people to a kitchen, 14 men to a single bathroom, with a boarded-up hole where the rats crawled through and a bathroom window that is sealed shut.

Such crowded confines can make the transmission of disease more likely. In February this year, one Romanian worker on the site became extremely ill. Following several trips to the hospital, it was confirmed he had active tuberculosis, Investigate Europe was shown the individual’s medical record confirming the positive diagnosis. Shortly after, others showed similar symptoms.

After the first worker who contracted the disease had left for hospital, workers in the accommodation became worried about possibly also getting the disease.

One worker who had recently moved into a new room said: “I bought bedding myself, washed the mattress with chlorine, scrubbed the walls, left the window open for a long time - it was very cold.”

Benbau initially informed only a few men who shared close quarters with the first infected worker and then told the men testing was optional, according to seven workers who spoke with Investigate Europe. Freedom of information requests to Sweden’s national work authorities and Public Health Agency revealed no outbreak had been reported.

The county medical officer in Gävle told Investigate Europe that only one case was reported in March and shared with the national health authority, which also confirmed the case. In Sweden, tuberculosis is a notifiable disease that is subject to mandatory contact tracing, which workers claim did not occur.

Eight Benbau workers living in the same housing and union representatives told reporters that they believed at least 10 to 12 men also had the infectious disease.

Mihai*, a 60-year-old worker, also tested positive for tuberculosis, hospital records shared with Investigate Europe reveal. He says that Benbau offered to transfer him to another Microsoft site in Denmark, along with others he claims were also infected. Considering his age, Mihai says he decided against traveling.

Then, in May 2026, witnesses who lived in the housing where some were confirmed positive with latent tuberculosis say a group of vans arrived to relocate workers to the Denmark site. Two of the witnesses say that many of those who left that day had tested positive for tuberculosis. Some men were diagnosed with latent tuberculosis, yet told reporters they experienced symptoms weeks before.

Others who left that day, including an entire crew who worked in concrete for Benbau, had tuberculosis symptoms, the witnesses claim. In total, approximately 40 men left for Denmark that day, according to witnesses.

The Danish construction union 3F Byggegruppen says their records show around 45 posted workers arriving at the Microsoft site in Høje Taastrup around this time. No further record of what happened to any of the men is available, despite efforts from 3F to reach Benbau employees.

The 50-year-old worker who moved into the bedroom says that he had to get tested in Romania. He said that he was scared that if bosses found out he was speaking to the media, “that I would be sent to Denmark too.”

‘They rule on mental terror’

Workers say for the first few years, the working environment at Collen and Benbau wasn’t too difficult. But in the last two years, with the accelerated build-up of AI infrastructure, the mood has shifted. “It now feels like we are in the army service,” one Romanian worker told Investigate Europe in a video call with other colleagues. “They rule on terror, mental terror.”

Workers allege they are subject to a regime of daily harassment and regularly shifting rules. Many say the language barrier creates ongoing problems. To monitor workplace safety, the general contractor, Collen, introduced a football-style violation system. These orders, implemented by Benbau, consist of ‘yellow cards’ and ‘red cards’ for perceived infractions.

‘Carded’ workers describe being interrogated by managers for hours, then made to write letters admitting wrongdoing to workplace incidents even if they feel they have not done anything wrong.

“We are forced to sit in a room and confess to things we had not done,” one worker claims. Following a violation, they are then sent to attend a ‘reinduction’ training in English, and not their native Romanian.

Under another program, called ‘Goodsaves’, workers are required to report site or worker issues twice a week. Failure to do so results in threats of further pay deductions and extra training, texts seen by Investigate Europe show.

“These are control mechanisms,” insists one worker who asked not to be named.

“On Friday there’s the first message: ‘You have by 12 o’clock to finish your [reports]’. Then after 12 the threats begin: ‘You need to do your [report], do you want to work on Saturday?’ Then the last threat is: ‘We are going to cut the [missing report] out of your wages.’”

A former manager from Romania who worked for Benbau, who had decent housing and a wife and young child on site, told Investigate Europe he “refused to participate in the interrogation sessions” as a translator. He believes the written confessions were “designed to humiliate” other colleagues.

“In that atmosphere, I couldn’t continue seeing people working like this,“ he says. “I did not want to be afraid of someone who is forcing men to work 13 hours a day. I talked with my wife and I said: ‘This is the moment we need to go back to our country.’”

European unionization encounters US Big Tech

The living conditions and working climate form only part of the story.

Over 30 workers shared hundreds of pay slips with Investigate Europe, many show them working up to 60-hour weeks with no overtime pay, in an apparent violation of Swedish labor law. Some workers claim they have received no paid holiday as required under Swedish law for five years.

Solidariska byggare (Workers in Solidarity), a union group, has tried to recover years of backpay for migrant workers at the Gävle site, who have been paid up to 30 per cent less than their Swedish counterparts.

Historically, Sweden has operated under a self-regulated labor market system where trade unions and employer organizations set wages and working conditions through collective agreements rather than state-mandated laws. Unions now say that over the years this model is beginning to not only erode, but crack wide open.

As data center sites expand, the ever-lengthening chain of subcontractors involved becomes more challenging to track.

Documents obtained from a freedom of information request to Sweden’s Work Environment Authority reveal 148 firms working under Collen at the Gävle site, including 28 direct subcontractors. One subcontractor can have more than a dozen firms beneath them.

In Sweden, it is customary, though not legally required, for clients to demand a collective agreement clause in their public procurement calls for tender. Yet when Collen broke ground in 2019 for the Microsoft Gävle site, no such agreement was in place. Soon after, many of its subcontractors, including Benbau, also passed over collective agreements with unions.

With the accelerated influx of US multinationals building in Europe, many companies working under them are willing to forgo collective agreements entirely, according to unions. With foreign workers unfamiliar with the laws, and the contractors setting the terms, inequity can arise quickly.

“It is a very clear picture,” says Pelle Sunvisson, a union leader at Solidariksa byggare. He describes what he sees when handing out leaflets outside the Microsoft site in Gävle.

“At 4 o’clock there is a wave of Swedish workers. They are typically electricians working with Swedish companies that have Swedish collective agreements. If you wait an hour, then there is a smaller group of white-collar Irish workers leaving, and then around six you get some Polish, Romanian, Serbian workers. Then at seven or eight o’clock, all the workers [from outside Europe].”

Over the past several months, dozens of Romanian workers at Benbau have begun joining Solidariskans byggare. Negotiations with Benbau to obtain unpaid wages recently stalled, and the union considered holding a blockade at the site, accusing the company of withholding nearly 10 million Swedish kronor (€900,000) in wages and back pay for 78 men.

“Since migrant workers don’t know the system, there is a big black hole in the Swedish model, where it becomes like a lawless territory,” says Sunvisson.

“We have people cheated, who don’t get their salaries, even the low salary that has been promised. Some people [in the construction industry] are working five months for €500, with physical and verbal violence.”

Data obtained from freedom of information requests to the Swedish Work Environment Authority show that since 2019, the Irish company Winthrop has been fined 12 times for failing to meet core reporting requirements for foreign workers at its Swedish data center sites. In one unannounced inspection in 2021, authorities noted 15 different nationalities working at Winthrop on the Microsoft site in Sandviken.

Since 2021, the Work Environment Authority has opened 50 cases into data center sites involving Microsoft and Irish firms Winthrop, Collen and Mercury. The records, dating from 2021 to 2026, show a number of risks identified, including a serious danger of workers being struck by passing vehicles and machines falling into excavations.

Other inspections noted a lack of fixed fall protection, including suitable guardrails and platforms. One inspection of Collen in 2024 resulted in an immediate stop-work order and a conditional fine for failing to take adequate measures around fall protection. It stated the company’s lack of protection posed an immediate and serious danger of personal injury.

In October 2021, a forklift ran over the foot of a supervisor working for Collen in Gävle. The worker subsequently needed surgery. An incident report submitted by Collen to work authorities found the wrong machine had been used, the driver had no formal certificate for it and the lift plan was incomplete. Still, it had been signed off. In its accident report, the subcontractor listed both the injured man and the driver as self-employed.

The Work Environment Authority saw no grounds to report the employer to prosecutors.

When approached for comment, Collen declined to address specific issues raised but a spokesperson said the allegations were “wholly inconsistent with Collen’s values, policies and the standards to which we hold ourselves and those with whom we work.”

“We are committed to ensuring that every Collen site is a safe, healthy and respectful place to work, where everyone is treated with dignity and their fundamental human rights are protected,” the spokesperson added. “We expect the same throughout our supply chain and have zero tolerance for any conduct inconsistent with these principles.”

‘Beyond this gate, it is not the Netherlands’

It is not just in Sweden that workers have reported problems. Pyotr Zaitsev*, an engineering manager, worked on data center sites for another Irish construction firm in Germany until 2019.

Pyotr was highly experienced, and his daily tasks involved managing electrical installations while supervising groups of subcontractors. But he would regularly work beyond his contracted hours, he claims. He had “a contract for 40 hours a week on paper,” but in reality, “I was actually working 60 hours minimum, up to 80 hours from time to time.”

Hearing that the working conditions were better in the Netherlands, he found a job at a number of large Winthrop sites there.

Yet after 18 months, the pressure at Winthrop began to match that of his former employer, he claims, saying he had “severe burnout.” One day in 2021, after working a full shift, Pyotr says he fainted on site from overexertion. In an email to Winthrop’s HR department sent the following week, he informed the company he had gone to the hospital without specifying why.

Winthrop said they had no record of such an incident. "It is company policy that all adverse events must be reported, investigated and comprehensively recorded.”

He also said he had growing concerns for workplace safety. There was once a serious incident with a Romanian subcontractor, he claims: “There was a [mobile elevated working platform],” he describes, “the [the worker] was distracted and he was using the remote control and he drove over his [own] leg.”

Winthrop said they conducted an analysis and that the employee returned to work the next day, adding that it adhered to all applicable laws. “Winthrop is committed to maintaining the highest standards of health and safety across their projects, ensuring our people, partners and clients can operate in a safe and supportive environment,” a spokesperson said. “We place safety at the heart of project delivery.”

Pyotr has been on sick leave from the company since 2023. In May 2025, a Dutch government employment body ordered Winthrop to give Pyotr extended sick pay until May 2026, after finding the company had not fulfilled their obligations in helping him return to work. Winthrop stopped paying him in September 2025.

A Winthrop spokesperson said: “Despite repeated efforts to re-integrate the employee since he left in 2023 following a non-work-related accident outside the workplace, no progress was made in terms of the employee resuming work.”

Accessing data center sites to inspect worker conditions can be challenging, according to FNV, the Netherlands’ largest trade union.

Its representatives claim they attempted to access the Winthrop site in Schiphol-Rijk in September to speak to workers. At the gate, a Winthrop employee refused them entry, reportedly telling them, “Beyond this gate, it’s not the Netherlands… I am not allowed to let you in by upper management.”

FNV claims it has made several unsuccessful attempts, including an email request in summer 2026, to visit the Winthrop-Microsoft site in the past year.

A spokesperson for Winthrop said that union representatives were granted access through “pre-arranged protocols” across their data center sites.

“Any suggestion that unions are denied access to sites is false and misleading,” the spokesperson said.

The vast majority of Dutch construction companies are bound by a collective labor agreement that allows unions access to the sites. Foreign companies are not automatically covered by those agreements.

‘Sites are more closed than a state prison’

Belgian, Swedish, Danish, Finnish and Italian unions all told this investigation that they have had trouble accessing data center sites or have been shut out entirely.

Lotta Sjölander, a representative at the national trade union Byggnads in Sweden, the largest in the country, says representatives have been unable to access the Microsoft sites in Gävle and nearby Sandviken “from the very beginning.”

The Danish construction union 3F Byggegruppen, comprising 56,000 members, is proud of its success in getting worker parity. Yet Christian Foli Jensen, a 3F union consultant, says gaining access to sites is a growing challenge. The problem, he says, is that “the clients don’t follow the normal way to do things, like on construction sites in Denmark. The sites are more closed than a state prison.”

Jussi Sakari, from the Finnish union Rakennusliitto, says they are normally able to gain access to sites, but with main contractors that have only recently been operating in Finland, it has taken longer.

“Things were more difficult with Winthrop at first,” Sakari says. The union says it has seen a number of reported issues related to sites across Finland. “Alongside wage theft, forced or bogus self-employment has emerged as a major issue in recent years,” he says.

A similar pattern is found at sites throughout Europe, says James McCabe, a regional representative for Unite the Union, an Irish-UK trade union for over 1.2 million workers.

“Everywhere we’ve encountered Irish data center contractors at tech giant data center sites, we’ve learned of lack of normal and meaningful union access, difficulty accessing information as well as serious concerns of labor crimes and exploitation of workers. Everywhere,” he says.

In Pero, on the outskirts of Milan, an Amazon data center is being built. The construction is split across two sites and involves two general contractors. On one of the sites, unions have never been allowed access to speak with workers. Investigate Europe was present at one of these attempts in September.

According to Carlo Rioldi, from the Italian Confederation of Workers’ Trade Unions, many workers are often afraid to speak to unions about their experiences on data center sites. "Workers don't tell unions about their problems for fear of retaliation and because they often don't know their rights," Rioldi said.

An Amazon spokesperson said: "We expect suppliers of goods and services for Amazon to adhere to our supply chain standards... informed by leading international standards and frameworks developed by the United Nations and the International Labor Organization.”

Europe’s data center construction sites expose a major enforcement gap. With fewer than 140 staff in 2025 to support labor law enforcement across the EU, the European Labor Authority remains overstretched and unable to tackle mounting issues.

In a reply to Investigate Europe, it acknowledged having “no independent inspection or enforcement powers” and being unable to “enter workplaces to collect evidence, investigate cases or impose sanctions.”

A number of fatal accidents have been reported at data center sites recently, including in the UK where a general contractor died while working on a development in London last year. Another fatality was reported in 2024 at an electrical substation being built for a Microsoft data center in the capital. Serious accidents have also been recorded this year at projects in Sweden, Norway and Belgium. Exploitative labor practices have also been found at projects internationally, including in Brazil.

Regulating a European problem

In response to these issues, the European Commission will soon formally propose a sweeping piece of legislation called the Quality Jobs Act, with the aim of improving worker protections while bringing into line better supply chain compliance. Crucially, it will call for joint liability throughout the subcontracting chains, while promoting direct employment.

A report on regulating subcontracting chains by MEP and rapporteur Johan Danielsson was recently adopted by the European Parliament, setting out its position ahead of the upcoming legislation. He hopes that any specific proposal works with “subcontracting liabilities”, and believes that if you put workers at risk you have to put sanctions on a level that makes sense in proportion to the size of the company.

“If people let these big American multinationals come here and import their anti-union business models, then it becomes a problem,“ he said. “Because behind the fence they are abusing workers, and they don’t want anyone to know it. This is their business model.”

A Microsoft spokesperson said: “Microsoft is committed to ensuring that everyone working on its behalf is treated fairly, in line with Swedish labor law and our Supplier Code of Conduct. In our data center construction, we work with contractors and suppliers, with whom we set clear requirements on health and safety, working conditions, and the freedom of association and right to collective bargaining.”

Days before publication of this investigation, Solidariska byggare, the union representing the 78 Romanian workers at Microsoft’s site in Gävle, brokered an historic 15 million Swedish Krona (€1.3 million) settlement with Benbau.

“This will be the first collective agreement in Sweden’s history for, and by, migrant workers,” Sunvisson told Investigate Europe. Workers will receive millions in backpay and damages, says the union leader, and they have now “secured salaries well above the Swedish average.”

The agreement also allows unions access to all data center sites where Benbau works. “The company also cannot hold separate meetings anymore with workers without a union representative present,” Sunvission adds. Upon hearing the news, he describes an atmosphere of joy and relief amongst the men. “No one is afraid anymore.”

A spokesperson for Benbau said the company “takes all concerns regarding the welfare, health and safety of our people extremely seriously” and has “stringent procedures for reporting, investigating and addressing workplace concerns.”

They added: “Looking after our people is a responsibility we take very seriously. We invest in their welfare and wellbeing and place considerable value on retaining our team.”

Benbau failed to address specific allegations put to them by Investigate Europe but confirmed the collective agreement in Gävle “was signed by all parties over the weekend.”

Meanwhile, after his accident on the Google site in Belgium, Sandu is largely confined to his home in southeastern Romania. He is triggered by noise, and intolerant to sunlight. He suffers from anxiety and flashbacks of the incident. He has undergone numerous skin grafts, and his body is so sensitive he says he can barely be touched. Doctors tell him that he may regain use of only 70 per cent of his right hand and arm.

He worries for the future and how he will provide for his young family. While Dornan paid for Sandu’s flights and hotels, his recruitment company has failed to reimburse his expenses as initially promised, leaving him thousands out of pocket, he claims.

Still not fit enough to work, he struggles to pay for his six-year-old son’s schooling: “There are so many things that many people don’t understand.”

Dornan said it supported Belgian authorities with their investigation. A spokesperson added: “We were deeply concerned by this incident and have supported the individual and his family throughout his recovery. We are committed to maintaining safe working conditions, complying with applicable labor laws, and continually learning to help prevent incidents like this from happening again.”

“I think you have to think about these people working on these sites not just as workers, but as human beings,” says Sjölander from the Swedish union Byggnads. “As a person, you have to decide: how do you want your data… based on dignity or built off human lives?”
