The Twin Cities’ Corporate Concentration
The Twin Cities hosts a disproportionate concentration of corporate power: 17 Fortune 500 companies (2025 list) call Minnesota home, the highest per-capita density in the nation. HF 100 fundamentally rewrote the rules governing how these employers can test for cannabis.
The Minnesota Fortune 500 List
- UnitedHealth Group (#3 on the Fortune 500) — Minnetonka
- Target Corporation (#41) — Minneapolis
- U.S. Bancorp (#105) — Minneapolis
- Best Buy (#108) — Richfield
- 3M (#174) — Maplewood
- General Mills (#216) — Golden Valley
- Ameriprise Financial (#230) — Minneapolis
- CHS — Inver Grove Heights
- C.H. Robinson — Eden Prairie
- Land O’Lakes — Arden Hills
- Ecolab — St. Paul
- Xcel Energy — Minneapolis
- Hormel Foods — Austin
- Thrivent Financial — Minneapolis
- Solventum — Maplewood
- Securian Financial — St. Paul
- Fastenal — Winona
Plus other major operations: Medtronic (no longer legally domiciled in MN after the 2015 Covidien merger but maintains major operations in Minneapolis and Fridley), and Cargill (the nation’s largest private company, headquartered in Wayzata but excluded from the Fortune 500 as a private firm).
Minnesota DATWA — The Pre-HF 100 Framework
Minnesota’s Drug and Alcohol Testing in the Workplace Act (DATWA), codified at Minn. Stat. §§ 181.950–957, has regulated workplace drug testing since 1987. DATWA was always one of the more worker-protective frameworks in the U.S., requiring rehabilitation-first approaches and limiting employer testing discretion in various ways.
The HF 100 Amendments — Cannabis Removed from "Drug" Definition
HF 100 amended DATWA to remove cannabis from the statutory definition of "drug" — meaning pre-employment cannabis testing is now largely prohibited for most positions. Employers cannot refuse to hire solely because an applicant tests positive for cannabis.
The amended Lawful Consumable Products Act (Minn. Stat. § 181.938) additionally protects employees from discipline or termination for using cannabis off the employer’s premises during nonworking hours.
What Employers Can Still Do
These protections have specific carve-outs. Employers may still test for cannabis in:
- Safety-sensitive positions (where impairment would threaten health or safety)
- Peace officer and firefighter roles
- Positions requiring face-to-face care for children or vulnerable adults
- CDL-holders and DOT-regulated positions
- Any role where federal law or grant conditions require testing
Employers retain full authority to:
- Prohibit possession, use, and impairment during work hours and on work premises
- Conduct reasonable-suspicion and post-accident testing
- Maintain drug-free workplace policies for safety-sensitive operations
How This Plays Out at the Twin Cities Fortune 500
UnitedHealth Group (Minnetonka)
UnitedHealth likely retains testing authority for healthcare-facing positions (where patient safety considerations apply) but not for corporate staff (HR, finance, IT, marketing).
Target Corporation (Minneapolis)
Target probably cannot test most retail workers pre-employment but may test warehouse and distribution roles as safety-sensitive (forklift operators, etc.).
3M (Maplewood)
3M can likely test manufacturing positions involving heavy machinery but not corporate roles. Significant federal-contractor work may also create testing carve-outs for affected positions.
Best Buy (Richfield)
Similar to Target — retail roles likely protected; warehouse/distribution and Geek Squad roles handling sensitive customer property may be safety-sensitive.
General Mills (Golden Valley)
Manufacturing and distribution positions likely safety-sensitive; corporate roles protected.
U.S. Bancorp, Ameriprise, Securian, Thrivent
Financial services corporate roles generally protected. Some compliance and security positions may have additional considerations.
Ecolab, Solventum, Fastenal
Significant operational/manufacturing/distribution workforces — safety-sensitive testing applies to those roles.
The Federal-Contractor Carve-Out
A critical tension remains: companies receiving federal contracts or grants, or operating in federally regulated industries, face a conflict between Minnesota’s protective framework and federal prohibition. HF 100 includes a carve-out allowing continued cannabis restrictions where failure to comply would "violate federal or state law or regulations or cause the employer to lose a monetary or licensing-related benefit under federal law."
Federal-contractor employees in Minnesota remain fully exposed to federal Drug-Free Workplace Act requirements. AMMA / medical patient status does not protect them.
The Strongest Worker Protections in the Country
DATWA’s rehabilitation-first requirement — mandating that employers offer treatment rather than termination for first-time positive tests in non-safety-sensitive roles — combined with the HF 100 cannabis-removal amendments, makes Minnesota’s combined protections among the strongest worker cannabis protection frameworks in the country.
Practical Job-Hunting Advice
- Most Twin Cities corporate roles do not pre-employment cannabis test. Bringing a positive THC test to a UnitedHealth IT job interview, a Target marketing role, a 3M corporate finance position, or similar should not affect hiring under HF 100.
- Safety-sensitive roles still test. Manufacturing operators, warehouse workers, healthcare workers in direct patient care, financial-services compliance roles, and federal-contractor positions remain testable.
- DOT-regulated positions still test. Truck drivers, pilots, transit operators, etc.
- Federal-contractor positions still test. Even at otherwise corporate-friendly Fortune 500 employers.
- Ask early. Most employers will tell you up front whether the role is testable.
