    After Gains at Big Three, U.A.W. Aims at Nonunion Plants

    A looming union election at a Volkswagen plant in Chattanooga could determine the trajectory of union organizing at more than a dozen auto factories.When Shawn Fain, the United Automobile Workers president, unveiled the deal that ended six weeks of strikes at Ford Motor in the fall, he framed it as part of a longer campaign. Next, he declared, would be the task of organizing nonunion plants across the country.“One of our biggest goals coming out of this historic contract victory is to organize like we’ve never organized before,” he said at the time. “When we return to the bargaining table in 2028, it won’t just be with the Big Three. It will be the Big Five or Big Six.”Four months later, the first test of that strategy has come into focus, and it features a Volkswagen plant in Chattanooga, Tenn.According to the union, more than half of over 4,000 eligible workers have signed cards indicating support for a union. Workers say they have done so because they want higher pay, more paid time off and more generous health benefits — and because the recent strikes at Ford, General Motors and Stellantis persuaded them that a union can help win these concessions.“The Big Three, they had their big campaign, and their big strike and vote, and new contracts — we paid attention to that very closely,” said Yolanda Peoples, who has worked at the Volkswagen plant for nearly 13 years.The Volkswagen plant announced an 11 percent pay increase shortly after the strikes at the Big Three. The raise brought the top hourly wage for production workers to $32.40, but the comparable wage for the Detroit automakers will exceed $40 by the end of the new contracts. (Volkswagen said the wage adjustment was part of a yearly review.)We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Starbucks and Union Agree to Work Out Framework for Contract Talks

    In an initial move, the coffeehouse chain said Workers United members would get improved benefits that other employees received in 2022.Starbucks and the union that represents employees in roughly 400 of its U.S. stores announced Tuesday that they were beginning discussions on a “foundational framework” that would help the company reach labor agreements with unionized workers and resolve litigation between the two sides.The union greeted the development as a major shift in strategy for Starbucks, which has taken steps to resist union organizing at the company since the campaign began in 2021, moves that federal labor regulators have said violated labor law hundreds of times.Starbucks, which has denied the accusations, said in a statement that it hoped to have contracts negotiated and ratified by the end of the year and would agree to a “fair process for organizing” — something the union has demanded for years. It said that, as a gesture of good faith, it was providing unionized workers with benefits it introduced in 2022 but withheld from union stores, like an option for customers to tip via credit card.Representatives of both Starbucks and the union, Workers United, said that while details must be worked out, they hoped to be back at the bargaining table in the coming weeks. Negotiations between the two sides had largely lapsed over the past several months.Workers who have helped lead the organizing said the development had surprised them. “It still feels pretty surreal right now,” said Michelle Eisen, a longtime barista at a Starbucks in Buffalo that was the first company-owned store to unionize during the current campaign. “There has not been a single call I’ve been on today where either I wasn’t crying or everyone else wasn’t crying.”If a framework is agreed to and quickly leads to contracts, experts said, it could be a major development in labor relations in corporate America, where companies like Amazon and Apple have resisted union organizing to varying degrees.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Amazon Argues National Labor Relations Board Is Unconstitutional

    The company made the novel claim, echoing arguments by SpaceX and Trader Joe’s, in a legal filing while fighting a case.In the latest sign of a growing backlash within corporate America to the 88-year-old federal agency that enforces labor rights, Amazon argued in a legal filing on Thursday that the National Labor Relations Board was unconstitutional.The move followed a similar argument by SpaceX, the rocket company founded and run by Elon Musk, in a legal complaint in January, and by Trader Joe’s during a labor board hearing a few weeks later.The labor board consists of a prosecutorial arm, which issues complaints against employers or unions deemed to have violated federally protected labor rights; administrative judges, who hear complaints; and a five-member board in Washington, to which decisions can be appealed.Amazon’s filing was part of a case before an administrative judge in which labor board prosecutors have accused Amazon of illegally retaliating against workers at a Staten Island warehouse known as JFK8, which unionized two years ago.The company’s lawyers repeatedly denied in their filing that Amazon had broken the law. Then, under a section titled “Other Defenses,” they argued that “the structure of the N.L.R.B. violates the separation of powers” by “impeding the executive power provided for in Article II of the United States Constitution.”The company also argued that the board or its actions or proceedings violated Articles I and III of the Constitution, as well as the Fifth and Seventh Amendments — in the last case because, the filing said, board hearings can seek legal remedies beyond what’s allowed without a trial by jury.Amazon declined to comment.The claims it made in the filing echo arguments that lawyers for SpaceX made in a federal lawsuit last month, after the labor board issued a complaint accusing the company of illegally firing eight employees for criticizing Mr. Musk. SpaceX sued in Texas, but a federal judge there on Thursday granted the board’s motion to transfer the case to California, where the company’s headquarters are located.In a statement, the board’s general counsel, Jennifer A. Abruzzo, said, “I am pleased that SpaceX’s blatant forum-shopping efforts in Texas attempting to enjoin the agency’s litigation against it have failed.”Wilma Liebman, a chairwoman of the labor board under President Barack Obama, called the arguments by Amazon and SpaceX “radical,” adding that “the constitutionality of the N.L.R.B. was settled nearly 90 years ago by the Supreme Court.”The arguments appear to align with a broader conservative effort to question the constitutionality of a variety of regulatory actions, some of which have resulted in cases before the Supreme Court.In January, the Supreme Court also agreed to hear a case brought by Starbucks, which is challenging a federal judge’s order reinstating employees who were fired during a union campaign. The outcome of the case could rein in the labor board’s longstanding practice of seeking reinstatement for workers while their cases are litigated, a process that can take years. More

    Supreme Court to Hear Starbucks Bid to Overturn Labor Ruling

    The coffee chain has challenged a federal judge’s order to reinstate a group of union activists who were fired at a store in Memphis.The Supreme Court agreed on Friday to hear a case brought by Starbucks challenging a federal judge’s order to reinstate seven employees who were fired at a store in Memphis amid a union campaign there.Starbucks argued that the criteria for such intervention by judges in labor cases, which can also include measures like reopening shuttered stores, vary across regions of the country because federal appeals courts may adhere to different standards.A regional director for the National Labor Relations Board, the company’s opponent in the case, argued that the apparent differences in criteria among appeals courts were semantic rather than substantive, and that a single effective standard was already in place nationwide.The labor board had urged the Supreme Court to stay out of the case, whose outcome could affect union organizing across the country.The agency asks federal judges for temporary relief, like reinstatement of fired workers, because litigating charges of unfair labor practices can take years. The agency argues that retaliation against workers can have a chilling effect on organizing in the meantime, even if the workers ultimately win their case.In a statement on Friday, Starbucks said, “We are pleased the Supreme Court has decided to consider our request to level the playing field for all U.S. employers by ensuring that a single standard is applied as federal district courts.”The labor board declined to comment.The union organizing campaign at Starbucks began in the Buffalo area in 2021 and quickly spread to other states. The union, Workers United, represents workers at more than 370 Starbucks stores, out of roughly 9,600 company-owned stores in the United States.The labor board has issued dozens of complaints against the company based on hundreds of accusations of labor law violations, including threats and retaliation against workers who are seeking to unionize and a failure to bargain in good faith. This week, the agency issued a complaint accusing the company of unilaterally changing work hours and schedules in unionized stores around the country.The company has denied violating labor law and said in a statement that it contested the latest complaint and planned “to defend our lawful business decisions” before a judge.The case that led to the dispute before the Supreme Court involves seven workers who were fired in February 2022 after they let local journalists into a closed store to conduct interviews. Starbucks said the incident violated company rules; the workers and the union said the company did not enforce such rules against workers who were not involved in union organizing.The labor board found merit in the workers’ accusations and issued a complaint two months later. A federal judge granted the labor board’s request for an order reinstating the workers that August, and a federal appeals court upheld the order.“Starbucks is seeking a bailout for its illegal union-busting from Trump’s Supreme Court,” Workers United said in a statement on Friday. “There’s no doubt that Starbucks broke federal law by firing workers in Memphis for joining together in a union.”Starbucks said it was critical for the Supreme Court to wade into the case because the labor board was becoming more ambitious in asking judges to order remedies like reinstatement of fired workers.The labor board noted in its filing with the Supreme Court that it was bringing fewer injunctions overall than in some recent years — only 21 were authorized in 2022, down from more than 35 in 2014 and 2015.A Supreme Court decision could in principle raise the bar for judges to issue orders reinstating workers, effectively limiting the labor board’s ability to win temporary relief for workers during a union campaign.The case is not the only recent challenge to the labor board’s authority. After the board issued a complaint accusing the rocket company SpaceX of illegally firing eight employees for criticizing its chief executive, Elon Musk, the company filed a lawsuit this month arguing that the agency’s setup for adjudicating complaints is unconstitutional.The company said in its lawsuit that the agency’s structure violated its right to a trial by jury.

    Federal Regulators Seek to Force Starbucks to Reopen 23 Stores

    The National Labor Relations Board says the locations were closed because of union organizing, violating federal law.Federal labor regulators accused Starbucks on Wednesday of illegally closing 23 stores to suppress organizing activity and sought to force the company to reopen them.A complaint issued by a regional office of the National Labor Relations Board argued that Starbucks had closed the stores because its employees engaged in union activities or to discourage employees from doing so. At least seven of the 23 stores identified had unionized.The agency’s move is the latest in a series of accusations by federal officials that Starbucks has broken the law during a two-year labor campaign.The case is scheduled to go before an administrative judge next summer unless Starbucks settles it earlier. In addition to asking the judge to order the stores reopened, the complaint wants employees to be compensated for the loss of earnings or benefits and for other costs they incurred as a result of the closures.“This complaint is the latest confirmation of Starbucks’ determination to illegally oppose workers’ organizing,” Mari Cosgrove, a Starbucks employee, said in a statement issued through a spokesperson for the union, Workers United.A Starbucks spokesman said, “Each year as a standard course of business, we evaluate the store portfolio” and typically open, close or alter stores. The company said it opened hundreds of new stores last year and closed more than 100, of which about 3 percent were unionized.The union campaign began in 2021 in the Buffalo, N.Y., area, where two stores unionized that December, before spreading across the country. More than 350 of the company’s roughly 9,300 corporate-owned locations have unionized.The labor board has issued more than 100 complaints covering hundreds of accusations of illegal behavior by Starbucks, including threats or retaliation against workers involved in union activity and a failure to bargain in good faith. Administrative judges have ruled against the company on more than 30 occasions, though the company has appealed those decisions to the full labor board in Washington. Judges have dismissed fewer than five of the complaints.None of the unionized stores have negotiated a labor contract with the company, and bargaining has largely stalled. Last week, Starbucks wrote to Workers United saying it wanted to resume negotiations.According to Wednesday’s complaint, Starbucks managers announced the closing of 16 stores in July 2022, then announced several more closures over the next few months.An administrative judge previously ruled that Starbucks had illegally closed a unionized store in Ithaca, N.Y., and ordered workers reinstated with back pay, but the company has appealed that decision.The new complaint was issued on the same day that Starbucks released a nonconfidential version of an outside assessment of whether its practices align with its stated commitment to labor rights. The company’s shareholders had voted to back the assessment in a nonbinding vote whose results were announced in March.The author of the report, Thomas M. Mackall, a former management-side lawyer and labor relations official at the food and facilities management company Sodexo, wrote that he “found no evidence of an ‘anti-union playbook’ or instructions or training about how to violate U.S. laws.”But Mr. Mackall concluded that Starbucks officials involved in responding to the union campaign did not appear to understand how the company’s Global Human Rights Statement might constrain their response. The rights statement commits Starbucks to respecting employees’ freedom of association and participation in collective bargaining.Mr. Mackall cited managers’ “allegedly unlawful promises and threats” and “allegedly discriminatory or retaliatory discipline and discharge” as areas where Starbucks could improve.In a letter tied to the report’s release, the chair of the company’s board and an independent director said the assessment was clear that “Starbucks has had no intention to deviate from the principles of freedom of association and the right to collective bargaining.” At the same time, the letter added, “there are things the company can, and should, do to improve its stated commitments and its adherence to these important principles.” More

    Amazon Is Cracking Down on Union Organizing, Workers Say

    More than a year and a half after Amazon workers on Staten Island voted to form the company’s first union in the United States, the company appears to be taking a harder line toward labor organizing, disciplining workers and even firing one who had been heavily involved in the union campaign.The disciplinary actions come at a time when union organizers appear to be gaining ground at a major air hub operated by Amazon in Kentucky, where they say they have collected union authorization cards from at least one-quarter of hourly employees. Workers must typically demonstrate at least 30 percent support to prompt a union election.In disciplining the employees, Amazon has raised questions about the extent to which they are free to approach co-workers to persuade them to join a union, a federally protected right. The general counsel of the National Labor Relations Board has said Amazon is breaking the law through a policy governing the access that off-duty workers have to its facilities, which Amazon invoked in the recent firing. The board is seeking to overturn the policy at an upcoming trial.Lisa Levandowski, an Amazon spokeswoman, said the recent disciplinary actions were strictly a response to rule violations, not to union organizing. “Employees have the choice of whether or not to join a union,” she said.The company’s off-duty access rule is “a lawful, common-sense policy,” she said, “and we look forward to defending our position.”The fired worker, Connor Spence, was a founder of the Amazon Labor Union, which won last year’s election on Staten Island. After a split within the union leadership, Mr. Spence helped start a separate group that sought to pressure the company to negotiate a contract at the warehouse, known as JFK8.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Doctors at Allina Health Form Union

    The physicians, at Allina Health in Minnesota and Wisconsin, appear to be the largest group of unionized doctors in the private sector.In the latest sign of growing frustration among professionals, doctors employed by a large nonprofit health care system in Minnesota and Wisconsin have voted to unionize.The doctors, roughly 400 primary and urgent-care providers across more than 50 clinics operated by the Allina Health System, appear to be the largest group of unionized private-sector physicians in the United States. More than 150 nurse practitioners and physician assistants at the clinics were also eligible to vote and will be members of the union, which will be represented by a local of the Service Employees International Union.The result was 325 to 200, with 24 other ballots challenged, according to a tally sheet from the National Labor Relations Board, which conducted the vote. In a statement, Allina said, “While we are disappointed in the decision by some of our providers to be represented by a union, we remain committed to our ongoing work to create a culture where all employees feel supported and valued.”The doctors complained that chronic understaffing was leading to burnout and compromising patient safety.“In between patients, your doctor is dealing with prescription refills, phone calls and messages from patients, lab results,” said Dr. Cora Walsh, a family physician involved in the organizing campaign.“At an adequately staffed clinic, you have enough support to help take some of that workload,” Dr. Walsh added. “When staff levels fall, that work doesn’t go away.”Dr. Walsh estimated that she and her colleagues often spend an hour or two each night handling “inbox load” and worried that the shortages were increasing backlogs and the risk of mistakes.The union vote follows recent walkouts by pharmacists in the Kansas City area and elsewhere over similar concerns.A variety of professionals, including architects and tech workers, have sought to form unions in recent years, while others, like nurses and teachers, have waged strikes and aggressive contract bargaining campaigns.Some argue that employers have exploited their sense of mission to pay them less than their skills warrant, or to work them around the clock. Others contend that new business models or budget pressures are compromising their independence and interfering with their professional judgment.Increasingly, doctors appear to be expressing both concerns.“We feel like we’re not able to advocate for our patients,” said Dr. Matt Hoffman, another doctor involved in the organizing at Allina. Dr. Hoffman, referring to managers, added that “we’re not able to tell them what we need day to day.”Consolidation in the health care industry over the past two decades appears to underlie much of the frustration among doctors, many of whom now work for large health care systems.“When a physician ran his or her own practice, they made the decisions about the people and technology they surrounded themselves with,” Dr. Robert Wachter, chair of the department of medicine at the University of California, San Francisco, said in an email. “Now, these decisions are made by administrators.”Doctors at Allina say that staffing was a concern before the pandemic, that Covid-19 pushed them to the brink and that staffing has never fully recovered to its prepandemic levels.Relatively low pay for clinical assistants and lab personnel appears to have contributed to the staffing issues, as these workers left for other fields in a tight job market. In some cases, doctors and other clinicians within the Allina system have quit or scaled back their hours, citing so-called moral injury — a sense that they couldn’t perform their jobs in accordance with their values.“We were promised that when we get through the acute phase of the pandemic, staffing would get better,” Dr. Walsh said. “But staffing never improved.”Allina, which takes in billions in revenue but has faced financial pressures and recently eliminated hundreds of positions, did not respond to questions about the doctors’ concerns.Joe Crane, the national organizing director for the Doctors Council of the S.E.I.U., which represents attending physicians, said that before the pandemic, he would receive about 50 inquiries a year from doctors interested in learning more about forming a union. He said he received more than 150 inquiries during the first month of the pandemic. (Mr. Crane was with another physicians’ union at the time.)Mr. Crane, citing the siloed nature of the medical profession, said that unionization among attending physicians had nonetheless proceeded slowly, but that the victory at Allina could create momentum.In March, more than 100 doctors voted to unionize at another Allina facility, a hospital with two locations. Dr. Alia Sharif, a physician involved in that union campaign, said doctors were under pressure there not to exceed length-of-stay guidelines for patients, even though many suffer from complex conditions that require more sustained care.Allina is appealing the outcome of that vote to the National Labor Relations Board in Washington; a board official rejected an earlier appeal.Even as rates of unionization have languished among attending physicians, they have increased substantially among medical residents. A sister union within the S.E.I.U., the Committee of Interns and Residents, has added thousands of members over the past few years.Dr. Wachter said this could herald an increase in unionization among doctors outside training programs. “When these physicians finish training and enter practice, they are more comfortable with a world in which unionization doesn’t automatically conflict with their notions of being a professional,” he wrote.

    Heat Is Costing the U.S. Economy Billions in Lost Productivity

    From meatpackers to home health aides, workers are struggling in sweltering temperatures and productivity is taking a hit.As much of the United States swelters under record heat, Amazon drivers and warehouse workers have gone on strike in part to protest working conditions that can exceed 100 degrees Fahrenheit.On triple-digit days in Orlando, utility crews are postponing checks for gas leaks, since digging outdoors dressed in heavy safety gear could endanger their lives. Even in Michigan, on the nation’s northern border, construction crews are working shortened days because of heat.Now that climate change has raised the Earth’s temperatures to the highest levels in recorded history, with projections showing that they will only climb further, new research shows the impact of heat on workers is spreading across the economy and lowering productivity.Extreme heat is regularly affecting workers beyond expected industries like agriculture and construction. Sizzling temperatures are causing problems for those who work in factories, warehouses and restaurants and also for employees of airlines and telecommunications firms, delivery services and energy companies. Even home health aides are running into trouble.“We’ve known for a very long time that human beings are very sensitive to temperature, and that their performance declines dramatically when exposed to heat, but what we haven’t known until very recently is whether and how those lab responses meaningfully extrapolate to the real-world economy,” said R. Jisung Park, an environmental and labor economist at the University of Pennsylvania. “And what we are learning is that hotter temperatures appear to muck up the gears of the economy in many more ways than we would have expected.”A study published in June on the effects of temperature on productivity concludes that while extreme heat harms agriculture, its impact is greater on industrial and other sectors of the economy, in part because they are more labor-intensive. It finds that heat increases absenteeism and reduces work hours, and concludes that as the planet continues to warm, those losses will increase.The cost is high. In 2021, more than 2.5 billion hours of labor in the U.S. agriculture, construction, manufacturing, and service sectors were lost to heat exposure, according to data compiled by The Lancet. Another report found that in 2020, the loss of labor as a result of heat exposure cost the economy about $100 billion, a figure projected to grow to $500 billion annually by 2050.A U.P.S. delivery in Manhattan on Monday.Spencer Platt/Getty ImagesOther research found that as the mercury reaches 90 degrees Fahrenheit, productivity slumps by about 25 percent and when it goes past 100 degrees, productivity drops off by 70 percent.And the effects are unequally distributed: in poor counties, workers lose up to 5 percent of their pay with each hot day, researchers have found. In wealthy counties, the loss is less than 1 percent.Of the many economic costs of climate change —- dying crops, spiking insurance rates, flooded properties — the loss of productivity caused by heat is emerging as one of the biggest, experts say.“We know that the impacts of climate change are costing the economy,” said Kathy Baughman McLeod, director of the Adrienne Arsht-Rockefeller Foundation Resilience Center, and a former global executive for environmental and social risk at Bank of America. “The losses associated with people being hot at work, and the slowdowns and mistakes people make as a result are a huge part.”Still, there are no national regulations to protect workers from extreme heat. In 2021, the Biden administration announced that the Occupational Safety and Health Administration would propose the first rule designed to protect workers from heat exposure. But two years later, the agency still has not released a draft of the proposed regulation.Seven states have some form of labor protections dealing with heat, but there has been a push to roll them back in some places. In June, Governor Greg Abbott of Texas signed a law that eliminated rules set by municipalities that mandated water breaks for construction workers, even though Texas leads all states in terms of lost productivity linked to heat, according to an analysis of federal data conducted by Vivid Economics.Business groups are opposed to a national standard, saying it would be too expensive because it would likely require rest, water and shade breaks and possibly the installation of air-conditioning.Martin Rosas, the vice president for the United Food and Commercial Workers Union International. “When it’s extremely hot, and their safety glasses fog up, their vision is impaired and they are exhausted, they can’t even see what they’re doing,” he said of the workers he represents.Brett Deering for The New York Times“OSHA should take care not to impose further regulatory burdens that make it more difficult for small businesses to grow their businesses and create jobs,” wrote David S. Addington, vice president of the National Federation of Independent Business, in response to OSHA’s plan to write a regulation.Marc Freedman, vice president of employment policy at the United States Chamber of Commerce, said, “I don’t think anyone is dismissing the hazard of overexposure to heat.” But, he said, “Is an OSHA standard the right way to do it? A lot of employers are already taking measures, and the question will be, what more do they have to do?”The National Beef slaughterhouse in Dodge City, Kan., where temperatures are expected to hover above 100 degrees Fahrenheit for the next week, is cooled by fans, not air-conditioning.Workers wear heavy protective aprons and helmets and use water vats and hoses heated to 180 degrees to sanitize their equipment. It’s always been hot work.But this year is different, said one worker, who asked not to be identified for fear of retribution. The heat inside the slaughterhouse is intense, drenching employees in sweat and making it hard to get through a shift, the worker said.National Beef did not respond to emails or telephone calls requesting comment.Martin Rosas, a union representative for meatpacking and food processing workers in Kansas, Missouri and Oklahoma, said sweltering conditions present a risk for food contamination. After workers skin a hide, they need to ensure that debris doesn’t get on the meat or carcass. “But when it’s extremely hot, and their safety glasses fog up, their vision is impaired and they are exhausted, they can’t even see what they’re doing,” Mr. Rosas said.Almost 200 employees out of roughly 2,500, have quit at the Dodge City National Beef plant since May, Mr. Rosas said. That’s about 10 percent higher than usual for that time period, he said.Maria Rodriguez, who has worked at the same McDonald’s in Los Angeles for 20 years, walked out on July 21.Jessica Pons for The New York TimesBut even some workers in air-conditioned settings are getting too hot. McDonald’s workers in Los Angeles walked off the job this summer as the air-conditioned kitchens were overwhelmed by the sweltering heat outside.“There is an air-conditioner in every part of the store, but the thermostat in the kitchen still showed it was over 100 degrees,” said Maria Rodriguez, who has worked at the same McDonald’s on Crenshaw Boulevard in Los Angeles for 20 years, but walked out on July 21, sacrificing a day of pay. “It’s been hot before, but never like this summer. I felt terrible — like I could pass out or faint at any moment.”Nicole Enearu, the owner of the store, said in a statement, “We understand that there’s an uncomfortable heat wave in LA, which is why we’re even more focused on ensuring the safety of our employees inside our restaurants. Our air-conditioning is functioning properly at this location.”Tony Hedgepeth, a home health aide in Richmond, Va., cares for a client whose home thermostat is typically set at about 82 degrees. Last week, the temperature inside was near 94 degrees.Any heat is a challenge in Mr. Hedgepeth’s job. “Bathing, cooking, lifting and moving him, cleaning him,” he said. “It’s all physical. It’s a lot of sweat.”Warehouse workers across the country are also feeling the heat. Sersie Cobb, a forklift driver who stocks boxes of pasta in a warehouse in Columbia, S.C., said the stifling heat can make it difficult to breathe. “Sometimes I get dizzy and start seeing dots,” Mr. Cobb said. “My vision starts to go black. I stop work immediately when that happens. Two times this summer I’ve had heart palpitations from the heat, and left work early to go to the E.R.”In Southern California, a group of 84 striking Amazon delivery workers say that one of their priorities is getting the company to make it safe to work in extreme heat. Last month, unionized UPS workers won a victory when the company agreed to install air-conditioning in delivery trucks.Amazon delivery drivers striking at the company’s Palmdale, Calif., warehouse and delivery center on Tuesday.Robyn Beck/Agence France-Presse — Getty Images“Heat has played a tremendous role — it was one of the major issues in the negotiations,” said Carthy Boston, a member of the International Brotherhood of Teamsters representing UPS drivers in Washington, D.C. “Those trucks are hotboxes.”Many factories were built decades ago for a different climate and are not air-conditioned. A study on the effects of extreme temperatures on the productivity of auto plants in the United States found that a week with six or more days of heat exceeding 90 degrees Fahrenheit cuts production by an average of 8 percent.In Tulsa, Okla., Navistar is installing a $19 million air-conditioning system at its IC Bus factory, which produces many of America’s school buses. Temperatures on the floor can reach 99 degrees F. Currently, the plant is only cooled by overhead fans that swirl high above the assembly line.Shane Anderson, the company’s interim manager, said air-conditioning is expected to cost about $183 per hour, or between $275,000 and $500,000 per year — but the company believes it will boost worker productivity.Other employers are also adapting.Brad Maurer, who leads a construction contracting business in Michigan, where heat has caused his employees to stop working hours before quitting time at some sites.Emily Elconin for The New York TimesBrad Maurer, vice president of Leidal and Hart, which builds stadiums, hospitals and factories in Michigan, Ohio, Indiana, Kentucky and Tennessee, said managers now bring in pallets of bottled water, which they didn’t used to do, at a cost to the company of a few thousand dollars a month.Rising heat around Detroit recently caused his employees to stop working three hours early on a Ford Motors facility for several days in a row — a pattern emerging throughout his company’s work sites.“It means costs go up, production goes down, we may not meet schedules, and guys and women don’t get paychecks,” Mr. Maurer said. Labor experts say that as employers adapt to the new reality of the changing climate, they will have to pay one way or the other.“The truth is that the changes required probably will be very costly, and they will get passed on to employers and consumers,” said David Michaels, who served as assistant secretary of labor at OSHA during the Obama administration and is now a professor at the George Washington School of Public Health.“But if we don’t want these workers to get killed we will have to pay that cost.”David Gelles More
