# Economic Analysis: Layoffs in Duncan, South Carolina

Overview: Scale and Significance of Workforce Displacement

Duncan, South Carolina has experienced modest but concentrated workforce disruption, with three WARN notices affecting 631 workers across a thirteen-year span documented in the data. This represents a relatively small absolute number compared to statewide displacement, yet the concentration among just three employers reveals a vulnerability to single-facility closures or major restructuring events that can significantly impact a community of Duncan's size. The 631 affected workers constitute the complete documented WARN activity for the municipality, indicating that when major employers do shed labor, the community experiences pronounced economic shock. The temporal distribution—one notice in 2015 and two clustered in 2020—suggests that Duncan experienced acute disruption during the pandemic-induced recession, a pattern consistent with national labor market turbulence but deserving of localized examination.

The Manufacturing-Driven Collapse: Automotive Supply Chain Vulnerability

Manufacturing dominates Duncan's layoff profile, accounting for 546 of the 631 affected workers, or 86.5 percent of total WARN-triggered displacement. This concentration reflects the municipality's dependence on automotive supply manufacturing, which emerged as a critical vulnerability during the 2020 economic contraction. Benteler, an automotive supplier headquartered in Austria with global operations, filed a single notice affecting 296 workers—nearly half of all documented layoffs in Duncan. ZF Chassis Systems, likewise a major automotive component manufacturer, accounted for 250 workers in one notice filing. Together, these two companies represent 87.3 percent of manufacturing displacement and 86.5 percent of total WARN activity.

The timing of the 2020 filings—coinciding with the initial COVID-19 pandemic shutdown and subsequent collapse of automotive production—indicates that Duncan's manufacturing base absorbed substantial contractionary pressure during the period when automotive assembly plants nationwide were shuttered and supply chain demand evaporated. Both Benteler and ZF Chassis Systems operate as Tier-1 and Tier-2 suppliers to major automakers, meaning their workforce adjustments reflect not direct consumer demand collapse but the cascading effects of upstream production halts at final assembly facilities. The 2015 layoff, by contrast, occurred during a period of economic expansion and automotive industry recovery, suggesting structural rather than cyclical workforce adjustment.

Healthcare's Marginal Presence and Emerging Service Sector Vulnerability

The healthcare sector represented only 85 workers across one WARN notice filed by United Health, representing 13.5 percent of Duncan's documented layoff activity. This relatively small contribution masks an important economic shift: while manufacturing defines Duncan's historical identity and layoff vulnerability, healthcare and service sectors are emerging as secondary sources of labor market disruption. United Health's presence in Duncan reflects the municipality's gradual economic diversification away from manufacturing-only employment, yet the single healthcare-sector WARN notice suggests this diversification remains incomplete. The absence of subsequent healthcare layoffs in the dataset does not guarantee sector stability; rather, it indicates that Duncan has not yet experienced the consolidation pressures, insurance reimbursement challenges, or clinic closures that have triggered WARN notices in other South Carolina communities.

Historical Trajectory: Episodic Rather Than Structural Decline

Duncan's layoff pattern reveals episodic workforce disruption rather than continuous economic deterioration. The 2015 notice represents the baseline structural adjustment typical of manufacturing communities during normal business cycles—routine capacity adjustments and plant optimization. The 2020 clustering, however, represents genuine economic shock. With two notices affecting 535 workers within the same calendar year, the municipality experienced concentrated displacement that would strain local unemployment insurance systems, workforce retraining programs, and household financial stability. The five-year gap between 2015 and 2020 suggests neither chronic decline nor sustained expansion but rather the boom-bust cyclicality characteristic of manufacturing-dependent regions vulnerable to both national recession and supply chain disruption.

The absence of WARN filings post-2020 does not necessarily indicate recovery. Firms often adjust workforce levels through natural attrition, reduced hours, or non-WARN-triggering layoffs below the 50-worker threshold rather than mass terminations. Duncan's silence on WARN filings since 2020 may reflect either stabilization of manufacturing demand or employer strategies designed to avoid regulatory visibility and community backlash.

Local Economic Impact: Community-Scale Disruption

For Duncan, a municipality where precise population data is not provided in the dataset but whose economic base appears heavily dependent on manufacturing, the loss of 631 jobs cumulatively represents substantial per-capita income loss and multiplier effects throughout the local economy. Manufacturing jobs typically offer above-median wages for workers without four-year degrees, meaning displaced workers face skill-to-wage mismatches in transitioning to available service-sector employment. Benteler and ZF Chassis Systems layoffs would have triggered household income losses, reduced local consumer spending, lower property tax revenues, and potential deterioration of local public services if significant numbers of displaced workers left the community or reduced consumption.

The 2020 layoffs occurred during a period when South Carolina's overall unemployment rate was rising sharply but ultimately remained manageable compared to national levels. However, Duncan's manufacturing base would have experienced steeper local unemployment than the statewide average during the immediate post-layoff period, creating concentrated hardship even as broader recovery began. The presence of United Health layoffs alongside manufacturing reductions suggests that 2020 disruption was not isolated to one sector, potentially indicating broader economic contraction rather than sector-specific adjustment.

Regional Context: Duncan Within South Carolina's Labor Market

Current South Carolina labor market indicators show relative tightness, with an insured unemployment rate of 0.67 percent as of April 2026—substantially below the national rate of 1.26 percent—and a state unemployment rate of 4.9 percent in January 2026. This favorable regional backdrop suggests that displaced Duncan workers, if still in the labor market, are benefiting from broader South Carolina expansion. However, this regional tightness masks localized weaknesses; Duncan's manufacturing base may not have fully recovered from 2020 disruption, and workers displaced from automotive supply manufacturing may lack ready pathways into emerging high-wage sectors.

South Carolina's robust H-1B visa activity, with 16,892 certified petitions and top employers concentrated in higher education and IT services, indicates that state economic development has shifted toward technology and research sectors centered in Clemson, Charleston, and Greenville rather than inland manufacturing communities like Duncan. The top H-1B occupations—Computer Systems Analysts, Software Developers, Mechanical Engineers—align with university and IT services hiring rather than automotive supply chain employment, suggesting that Duncan's traditional manufacturing workers may lack credentials for emergent statewide job growth.

Foreign Hiring Amid Domestic Displacement: The H-1B Question

The dataset provides no evidence that Benteler, ZF Chassis Systems, or United Health (Duncan operations specifically) engaged in simultaneous H-1B hiring while conducting WARN-triggering layoffs. However, the broader South Carolina H-1B data reveals a critical pattern: employers in technology and specialized engineering fields across the state maintain active foreign worker sponsorship programs while manufacturing communities experience domestic workforce reduction. This divergence suggests that South Carolina's economic transition away from manufacturing toward technology and healthcare administration creates winners and losers geographically and occupationally. Duncan workers displaced from automotive supply manufacturing lack the advanced degree credentials required for H-1B-adjacent roles like software development (average salary $455,362) or computer systems analysis (average salary $69,796), meaning they are systematically excluded from the visa labor markets that complement state economic growth.

Duncan's manufacturing legacy, while generating documented WARN activity reflecting real disruption, has not positioned the community to benefit from South Carolina's knowledge economy expansion.
