In the span of five months, OpenAI, BlackRock, and Meta have each signed formal labor agreements with North America's Building Trades Unions (NABTU). Meta's deal, announced August 12, adds a feature none of the others has: a single workforce program that formally covers both the union and the non-union construction labor markets at the same time. The partnership integrates NABTU's registered apprenticeship network into Meta's America's Workforce Academy, a $115 million first-year initiative launched in June 2026 with the Associated Builders and Contractors and CBRE. On August 10, NABTU signed a Memorandum of Understanding with BlackRock and the AI Infrastructure Partnership, structured around responsible contractor standards and project labor agreements. In March 2026, OpenAI announced a formal partnership with NABTU, committing $1.5 million over five years to support training and recruitment programs. OpenAI's chief global affairs officer Chris Lehane stated that reaching 10 gigawatts of compute by 2030 would require 20% more tradespeople than currently exist. In April 2026, OpenAI and NABTU turned the partnership into its first concrete project: a labor agreement to build the Oracle-OpenAI Stargate campus in Saline Township, Michigan, a multibillion-dollar facility expected to employ more than 2,500 NABTU tradespeople and apprentices.
