Labor Day 2025: Union Density Stays Flat at 10% Despite Absolute Member Gains

NewsData.io · United States · Sep 7, 2026

U.S. union density remained essentially flat at roughly 10% of the total workforce in the most recent data, with private-sector unionization at just under 6%, even as unions added 463,000 members in 2025 — the highest gain in 16 years — because the nonunion workforce is growing faster. The Trump administration's actions against public-sector unions, including canceling collective bargaining at several agencies and ending automatic dues deduction, are accelerating membership losses in government unions. Sectors most relevant to staffing — transportation, warehousing, construction, and healthcare — remain significantly above the private-sector average in union density, with implications for wage floors and placement conditions. Longer term, automation in trucking and AI-driven data center construction are shaping the next wave of labor demand and organizing activity.
