Kelly Services report finds 90% of U.S. data center operators cite staffing gaps as a critical build risk

A 25 August 2026 report from global staffing firm Kelly Services has put a hard number on what contractors and hyperscalers have been feeling on the ground: 90% of U.S. data center operators identify workforce gaps as a critical constraint on their ability to build or expand facilities, and nearly half of all projects scheduled for 2026 delivery face potential delays or cancellations due to staffing shortfalls^[1].

The finding lands at the peak of the largest data center construction cycle in U.S. history. Year-to-date construction spending through June 2026 reached $81.5 billion, already exceeding all of 2025's full-year total of $72.5 billion, according to ConstructConnect data. The sector is pulling capital away from every other nonresidential category - and it is now pulling workers away from them too.

A demand curve the labor market cannot match

Kelly's analysis, cross-referenced with U.S. Bureau of Labor Statistics data, found that data center employment is expected to reach 650,000 permanent positions by year-end 2026, a 30% increase from 2023, while data center-related construction jobs are projected to exceed 180,000 positions through 2028^[1]. The roles in shortest supply are not generalist construction labor - they are specialists:

• High-voltage electricians and electrical commissioning engineers
• Industrial HVAC and precision cooling technicians
• Fiber and structured-cabling installers
• Critical-systems project managers

The shortage is compounded by internal poaching. 25% of data center personnel are currently being hired away by competing hyperscalers and operators^[1], a dynamic Kelly describes as driving sector-wide wage inflation without resolving the underlying supply problem. "Data center employers are competing for many of the same specialized workers, and that approach can't keep pace with the level of infrastructure investment we're seeing," said Jake Rasweiler, Senior Vice President, Data Centers and Digital Infrastructure at Kelly.

Talent acquisition has overtaken power and land as the primary constraint

The report's framing is a notable shift from the narrative of 12 months ago, when grid interconnection queues and land availability dominated industry discussion. Kelly's analysis positions workforce availability as the single biggest barrier to keeping projects on schedule - ahead of power, equipment, and permitting.

The hyperscalers are responding with structural moves rather than simply raising wages. On 13 August 2026, Meta signed a national partnership with North America's Building Trades Unions (NABTU) to develop registered apprenticeship programs specifically for data center construction, covering high-voltage systems, cooling and fire suppression, and secure fiber networks. The deal sits alongside Meta's existing $115 million Workforce Academy initiative with the Associated Builders and Contractors and CBRE. OpenAI and BlackRock have signed separate NABTU memoranda of understanding on the same basis, with NABTU's apprenticeship network of roughly 300,000 enrolled trainees identified as a potential scale-up pathway to one million.

What Kelly recommends

Kelly's prescribed remedies move away from reactive poaching toward structural pipeline-building:

• Recruit from adjacent technical sectors - telecommunications, utility grid operations, and industrial HVAC - where transferable skills are high and competition is lower^[1]
• Implement rapid upskilling programs to bridge the gap between adjacent-sector experience and data center-specific requirements^[1]
• Begin workforce planning earlier in the project cycle, before shovels go in the ground

The cost of inaction is quantifiable. A 60 MW data center delayed by one month can cost an operator an estimated $14.2 million in lost revenue, according to separate industry analysis - a figure that makes even expensive apprenticeship programs look cheap by comparison.

The next pressure point to watch is the 2027 pipeline. With year-to-date construction starts already exceeding 2025's full-year total, the commissioning and operations workforce - not just the construction trades - will face the same acute shortage as built facilities come online and require permanent staffing. Operators that have not begun workforce planning for that phase are already behind.
