Worth knowing: South Carolina's RTW since 1954 (one of the original RTW states) substantially affects UA plumber market dynamics in SC and is a feature most national trade-career surveys understate. SC RTW + ~2.5% union density (one of the country's lowest) means UA Local 614 Charleston + UA Local 421 Greenville + UA Local 188 Columbia operate in a market where non-union open-shop plumbing contractors hold substantial market share — UA Locals retain commercial + industrial + cleared federal market presence but residential + smaller commercial work is predominantly non-union. SC's substantial post-2009 manufacturing buildout (BMW Spartanburg + Boeing 787 Charleston + Volvo Charleston + Mercedes-Benz Vans + Bosch + Michelin + tier-1/2 suppliers) created substantial post-2009 industrial plumbing demand supporting senior industrial plumbers at $92-135K TC across cleanroom + paint shop + process piping work. Savannah River Site Aiken (~10K cleared DOE workforce at the National Nuclear Security Administration's facility) supports substantial nuclear-grade process plumbing work — Q-cleared plumbers at SRS earn for classified nuclear work. The Charleston port + Port of Charleston Harbor Deepening project supports marine + industrial plumbing demand. The 2025 No Tax on Overtime federal deduction applies to SC plumber OT premium pay for tax years 2025-2028. SC's 6.5% top bracket has limited impact on most journeyman comp.
