HARRISBURG, Pa. — <\/span>Building trades unions \u2014 long fashioned as the voice of the American worker \u2014 are now intertwined with the richest companies in the world as they create America’s artificial intelligence economy.<\/p>\n Unionized workers are employed on a huge number of massive data center projects and scrambling to recruit new apprentices to feed the explosive demand. <\/p>\n They’ve also become an ally of tech giants and tech-friendly government officials, echoing the talking point that the United States is in a critical national security race with China for AI superiority.<\/p>\n Unions are a visible force in helping counter fierce opposition in communities<\/a> and hostile legislation in Congress and legislatures, often aligning with traditional Republican pro-business constituencies and forcing Democrats to choose between them and progressives who want to take a harder line.<\/p>\n Unions have aggressively answered complaints about data centers in ways that executives at tech giants and the development firms rarely do, unafraid to bluntly confront concerns about energy and water shortages, rising electric and water bills, or noise and quality-of-life objections.<\/p>\n \u201cWhen people say, you know, \u2018data centers are the root of all evil,\u2019 we\u2019re just saying, \u2018look, they do create a hell of a lot of construction jobs, which we live and work in your communities,’\u201d said Rob Bair, president of the Pennsylvania Building and Construction Trades Council.<\/p>\n Instead of \u201cbeing just a blunt \u2018no,’\u201d Bair said, communities should figure out what they need and ask the tech companies for it \u2014 such as improvements to the project’s plans or millions of dollars for local schools. \u201cIf you don\u2019t ask, you\u2019re never gonna get,\u201d he said.<\/p>\n With data center construction accelerating, unions are expanding training centers and seeing their ranks grow faster than many union leaders have ever seen. <\/p>\n Unions in a number of states are reporting skyrocketing man hours, apprentice classes doubling in size and training centers undergoing expansions in anticipation of more work coming.<\/p>\n Data centers consume at least 40% of work hours done by members of the Columbus-Central Ohio Building and Construction Trades Council, a top official, Dorsey Hager, estimated. It’s at least 50% for the International Brotherhood of Electrical Workers Local 26 in metropolitan Washington, D.C., spokesperson Don Slaiman said.<\/p>\n The umbrella North America\u2019s Building Trades Unions said it hit a record number of members and apprentices in 2025. <\/p>\n The organization’s president, Sean McGarvey, compared it to the build trades’ expansion in the 1950s. He attributes today’s growth to data centers, power plants and legislation under former President Joe Biden that subsidized the construction of semiconductor and electric vehicle battery factories, energy efficiency projects and grid transmission improvements.<\/p>\n Data centers’ voracious energy needs are setting off a power plant construction boom and delivering a one-two punch of new life to unions whose members also build and maintain boilers, ductwork, pipelines and other power infrastructure.<\/p>\n The Boilermakers Local 154, whose members have watched power plants shut down in southwestern Pennsylvania, went from recruiting zero apprentices for four years to now assembling a class of over 200 \u2014 and they need more, union official Shawn Steffee said.<\/p>\n For their part, tech giants say they need to train hundreds of thousands more workers in skilled trades. They are spending tens of millions of dollars on training programs, including partnerships with unions that they hire to build their multibillion-dollar projects.<\/p>\n \u201cAcross the country, highly skilled union construction workers are laying the foundation for the AI economy,\u201d Sam Altman, co-founder and CEO of OpenAI, said in a joint statement in March with McGarvey’s organization.<\/p>\n Google said the majority of labor used to build its data centers is unionized, and pointed to a $10 million grant to a union-backed electricians training program that it said would help expand the electrician workforce pipeline by 70%.<\/p>\n Mark McManus, the general president of the United Association of Union Plumbers and Pipefitters, whose members work on pipelines, data centers and power plants, acknowledged criticism that organized labor is getting in bed with the richest, most powerful companies in the world.<\/p>\n But he rejected it as unrealistic.<\/p>\n \u201cIf we chose as a union to have a moratorium on building the data centers because we didn\u2019t believe it was right for America, the data centers would still be getting built,\u201d McManus said. \u201cThey\u2019re not stopping because of organized labor.\u201d<\/p>\n His union has a strong relationship with tech companies, is hitting all-time highs in membership and, based on an internal survey, has members working on over 90% of the data center projects in the United States.<\/p>\n \u201cThat\u2019s a market share that we don\u2019t have in a lot of other industries,\u201d McManus said. \u201cSo it\u2019s pretty near and dear to us.\u201d<\/p>\n It’s difficult to pin down exactly how many data center projects involve union labor. An Associated General Contractors of America survey late last year suggested that the labor composition of data center construction likely mirrors the makeup of commercial construction, which is roughly one-third union, an AGC spokesperson said.<\/p>\n National unions have negotiated labor agreements on major projects, including an Oracle and OpenAI Stargate campus<\/a> in Michigan and the \u201cProject Blue\u201d data center campus in Arizona, with more in the works. <\/p>\n When Gov. Josh Shapiro stood with Amazon executives to announce that the tech giant would spend $20 billion on two data center projects in eastern Pennsylvania, Bair stood with them.<\/p>\n \u201cThis is really unique, what we\u2019re building here in this commonwealth. People coming together with common purpose to get stuff done,\u201d Shapiro said.<\/p>\n In statehouses, unions have worked against Maine’s since-vetoed proposal for a statewide data center moratorium<\/a>; standards proposed in Illinois, including requiring data centers to supply their own energy; and an end to Virginia’s sales tax exemption<\/a> that helped make it the world’s biggest data center destination.<\/p>\n Pennsylvania state Sen. Katie Muth said it has been difficult to collect support from fellow Democrats for her legislation to regulate data centers when it is competing with union-backed legislation that she views as weaker.<\/p>\n \u201cThe unions don\u2019t want to promote anything that would impede data center development,\u201d Muth said.<\/p>\n Union representatives have made their presence felt at packed council meetings in municipal buildings from St. Louis to Spring City, Pennsylvania.<\/p>\n Sometimes it’s not in a good way.<\/p>\n Speaking to the City Council in Joliet, Illinois, Alicia Morales complained that union members \u2014 who sat in the front row holding \u201cvote yes for union jobs\u201d signs \u2014 had been disrespectful and \u201cbullied a lot of people\u201d entering the meeting.<\/p>\n Sometimes, union representatives are the only people in a packed municipal meeting room to speak in favor of a project.<\/p>\n \u201cI just want to commend you guys, thanks for being the adults in the room,\u201d Chuck Curry, the president of Ironworkers Local 395, told City Council members in Hobart, Indiana, at a January meeting on an Amazon data center. \u201cKnowing the tax structure, knowing business, that most of the people here don\u2019t know.\u201d<\/p>\n ___<\/p>\n Follow Marc Levy at http:\/\/twitter.com\/timelywriter<\/a><\/p>\n<\/div>\n
