Building trades unions have emerged as the most powerful political allies of tech giants constructing massive AI data centers, creating an unprecedented alliance that's delivering record membership growth while simultaneously blocking stricter regulations at state and local levels. As data center construction accelerates across the country, unionized workers are experiencing a boom in employment and apprenticeships that union leaders compare to the construction expansion of the 1950s, while becoming a visible force that shapes municipal and state policy decisions.

Why Are Unions Becoming Tech Giants' Most Powerful Allies?

The partnership between tech companies like OpenAI, Google, Amazon, and Oracle with building trades unions represents a fundamental shift in how major infrastructure projects get built and approved in America. When Governor Josh Shapiro announced Amazon's $20 billion investment in two Pennsylvania data center projects, the president of the Pennsylvania Building and Construction Trades Council stood alongside him, signaling a new political reality. This alignment has given unions unprecedented leverage in municipal and state politics, where they're actively opposing regulations that would slow data center development.

The scale of this boom is staggering. According to union officials, data centers now consume at least 40 percent of work hours for members of the Columbus-Central Ohio Building and Construction Trades Council, and at least 50 percent for the International Brotherhood of Electrical Workers Local 26 in the Washington, D.C. area. The umbrella organization North America's Building Trades Unions reported hitting a record number of members and apprentices in 2025, a growth trajectory that union leaders attribute directly to data center construction.

"Across the country, highly skilled union construction workers are laying the foundation for the AI economy," said Sam Altman, co-founder and CEO of OpenAI, in a joint statement with the North America's Building Trades Unions in March.

How Are Unions Influencing Data Center Policy at the Local Level?

Union representatives have become visible and vocal presences at municipal council meetings from St. Louis to Spring City, Pennsylvania, often serving as the primary voices supporting data center projects when community opposition runs high. In some cases, they've been the only speakers in packed meeting rooms advocating for projects to move forward. This grassroots political presence has proven remarkably effective at countering fierce community opposition and hostile legislation in Congress and state legislatures.

The union strategy differs markedly from how tech executives typically engage with local concerns. Rather than dismissing objections, union leaders have aggressively addressed complaints about energy shortages, water consumption, rising utility bills, and quality-of-life impacts. Rob Bair, president of the Pennsylvania Building and Construction Trades Council, explained the union approach: instead of simply saying "no" to communities, unions encourage them to identify their needs and negotiate directly with tech companies for improvements or financial contributions.

Union political influence has blocked or weakened several regulatory efforts. In Maine, unions worked against a statewide data center moratorium proposal that was ultimately vetoed. In Illinois, they opposed standards that would have required data centers to supply their own energy. In Virginia, they defended the state's sales tax exemption that has made it the world's largest data center destination. Pennsylvania state Senator Katie Muth noted the difficulty of building Democratic support for stronger data center regulations when competing against union-backed legislation that she views as weaker.

Steps Unions Are Taking to Meet Explosive Demand for Skilled Workers

• Expanding Training Centers: Unions across multiple states are undergoing major expansions of their apprenticeship and training facilities to accommodate skyrocketing demand, with apprentice classes doubling in size in anticipation of continued growth.
• Recruiting New Apprentices: The Boilermakers Local 154 in southwestern Pennsylvania went from recruiting zero apprentices for four consecutive years to assembling a class of over 200 apprentices, and union officials say they need even more workers to meet demand.
• Negotiating Labor Agreements: National unions have secured labor agreements on major projects including an Oracle and OpenAI Stargate campus in Michigan and the "Project Blue" data center campus in Arizona, with additional negotiations underway.

The power plant construction boom is delivering additional benefits to unions whose members build and maintain boilers, ductwork, pipelines, and other power infrastructure. Data centers' voracious energy needs are driving a construction surge in power generation capacity, creating a "one-two punch" of new work for multiple construction trades. Tech giants are also spending tens of millions of dollars on training programs and partnerships with unions to expand the skilled workforce pipeline. Google announced a $10 million grant to a union-backed electricians training program designed to expand the electrician workforce by 70 percent.

What Does This Alliance Mean for Progressive Politics?

The union-tech company partnership has created a genuine political dilemma for Democrats. Unions have traditionally been a core Democratic constituency, but their enthusiastic support for data center development puts them at odds with progressive activists and environmental advocates who want stricter regulations on AI infrastructure. This dynamic forces Democratic politicians to choose between supporting organized labor's economic interests and backing progressive demands for stronger environmental and safety standards.

Mark McManus, general president of the United Association of Union Plumbers and Pipefitters, acknowledged the criticism that organized labor is aligning with the world's richest and most powerful companies. However, he argued that unions have little choice in the matter. "If we chose as a union to have a moratorium on building the data centers because we didn't believe it was right for America, the data centers would still be getting built," McManus stated. His union reports that members are working on over 90 percent of data center projects in the United States, a market share that union leaders view as too valuable to risk.

The exact proportion of data center construction that involves union labor remains difficult to pin down. An Associated General Contractors of America survey from late 2025 suggested that the labor composition of data center construction likely mirrors commercial construction overall, which is roughly one-third unionized. However, union officials claim significantly higher penetration rates on major projects, particularly those involving tech giants like OpenAI, Google, and Amazon.

This emerging alliance between unions and tech companies represents a fundamental realignment of American labor politics. As data center construction accelerates in the coming years, unions will likely maintain their political leverage to shape how AI infrastructure gets built, while simultaneously becoming targets of criticism from progressive activists who view them as obstacles to stronger environmental and safety regulations. The outcome of this tension will significantly influence how America builds its AI economy and who benefits from the jobs it creates.
