Jobs & Economy in Spring Hill
Spring Hill's economy is genuinely anchored by General Motors -- a real, large employer with real, current 2026 volatility disclosed honestly: fresh June 2026 investment alongside a January 2026 retooling layoff that drove Maury County's unemployment to the highest of any Tennessee county that April.

Learn moreA real, large GM manufacturing and battery-production base
GM's Spring Hill Manufacturing complex employs roughly 3,265 people at the core assembly plant per one count (more than 5,000 across GM's broader Spring Hill footprint per another), producing Cadillac LYRIQ, LYRIQ-V, VISTIQ, and (from 2027) Chevrolet Blazer and next-generation XT5 vehicles. The GM/LG Energy Solution Ultium Cells joint venture separately represents a $2.3 billion investment (announced 2021), targeting up to 1,700 jobs.
Real, current fresh investment in June 2026
In June 2026, GM announced a combined $275 million investment across the Spring Hill complex: $150 million in Spring Hill Assembly to support a future Cadillac internal-combustion product, and $125 million in Spring Hill GPS to support the future of the 2.7L engine program -- a real, current sign of continued commitment to the site.
A real, disclosed 2026 employment volatility, not glossed over
Early 2026 brought a real disruption: a $70 million retooling of the battery line to produce lithium-iron phosphate (LFP) cells for energy storage instead of EV batteries, part of a broader industry pullback after the federal EV tax credit was eliminated in late 2025. Roughly 700 Ultium Cells workers were temporarily furloughed beginning January 2026, driving Maury County's unemployment rate to 6.1% in April 2026 -- the highest of any Tennessee county that month. The rate recovered to 4.5% in May 2026 once the retooling ended and production resumed, evidence the spike was temporary rather than structural -- but a real illustration of the concentration risk that comes with an economy anchored around a single major employer's production decisions.
Beyond GM: healthcare and county-level employment
Maury Regional Health maintains three physician practices directly in Spring Hill plus adult and pediatric therapy, primary care, urgent care, and imaging/ambulatory-surgery/oncology joint-venture services -- a real, if smaller-scale, healthcare-sector employment presence layered on top of the dominant GM/manufacturing base. See healthcare and columbia-tn-topics.js's jobs-economy topic for the county's broader employment base (Maury Regional Medical Center, Columbia's own flagship hospital).
