# Economic Analysis: Layoffs in Duncan, Oklahoma

Overview: Scale and Significance of Duncan's Layoff Activity

Duncan, Oklahoma has experienced 983 worker separations across four WARN notices since 2007, representing a concentrated but episodic pattern of workforce disruption in a small metro area. While four notices may appear modest in absolute terms, the cumulative impact of 983 displaced workers in a city with a population of approximately 23,000 constitutes a significant labor market shock. To contextualize this figure: a single layoff event affecting 983 workers represents roughly 4.3 percent of Duncan's total population and a substantially larger proportion of the city's working-age population. The clustering of notices reveals that Duncan's employment base remains vulnerable to commodity cycles and corporate restructuring decisions made at distant headquarters, a pattern consistent with oil-and-gas-dependent communities throughout Oklahoma.

Dominance of Energy Sector: Halliburton's Outsized Impact

The energy sector's dominance in Duncan's layoff history is unambiguous. Halliburton, a multinational oilfield services corporation, filed two separate WARN notices affecting 643 workers, representing 65.4 percent of all documented separations in Duncan since 2007. Additionally, Halliburton Energy Services, a related entity, filed one notice affecting 240 workers, bringing the Halliburton corporate ecosystem to 883 workers displaced—or 89.8 percent of the total four-notice sample. This concentration reflects Duncan's historical identity as a hub for oil-and-gas services employment. Halliburton maintains significant operations in Duncan due to the city's proximity to productive oil and natural gas fields in the Anadarko Basin and its established infrastructure for energy sector logistics and support services.

The two Halliburton notices in 2020 are particularly noteworthy given the timing. April 2020 marked the collapse of crude oil prices triggered by the COVID-19 pandemic and the Russia-Saudi Arabia oil price war, which forced international energy companies to undertake emergency cost reduction programs. Halliburton, facing both demand destruction and pressure on margins, reduced its North American operations substantially. Duncan, as a non-core operations center relative to Halliburton's major hubs in Houston and Houston-area facilities, proved expendable during this contraction.

The remaining 100 workers displaced came from Haulmark Trailers, a manufacturing firm. This single notice underscores the presence of light industrial manufacturing supporting the energy sector—trailer manufacturing feeds directly into oilfield logistics and transportation networks. The absence of additional Haulmark Trailers notices in subsequent years suggests this was likely a one-time adjustment rather than a sustained contraction.

Industry Patterns and Structural Economic Forces

The industry breakdown reveals the fragility inherent in energy-dependent regional economies. Mining and energy operations generated two notices affecting 643 workers; utilities generated one notice affecting 240 workers; and manufacturing generated one notice affecting 100 workers. The dominance of extractive industries (643 workers from mining and energy alone) underscores Duncan's structural dependence on commodity price cycles over which local decision-makers exercise no control.

Utilities employment in Duncan is almost entirely tied to supporting energy infrastructure. Halliburton Energy Services, classified as a utility sector employer in this dataset, operates transmission, compression, and processing facilities integral to the midstream segment of oil and gas production. When energy companies cut capital expenditures and operational spending during downturns, the utilities subsector contracts proportionally.

This sectoral concentration creates compounding vulnerabilities. Unlike diversified metropolitan economies that can absorb layoffs in one sector through expansion in others, Duncan lacks sufficient employment breadth to absorb 983 separated workers across alternative industries. The city has experienced periodic recovery between 2007 and 2020, but each cycle leaves permanent scars in the form of population outmigration and human capital loss as displaced workers seek opportunities in larger metropolitan areas.

Historical Trends: Episodic Volatility Rather Than Sustained Contraction

Duncan's WARN notice history reveals three discrete periods: one notice in 2007, one in 2016, and two clustered in 2020. This pattern reflects not a steady decline but rather episodic responses to external shocks—specifically, the 2007-2009 financial crisis and energy sector recession, the mid-2015 to mid-2016 oil price collapse, and the 2020 pandemic-induced energy market disruption.

The nine-year gap between 2007 and 2016 suggests sufficient recovery to prevent major WARN filings during the 2010-2015 period, even as the broader U.S. labor market faced lingering headwinds from the Great Recession. However, the return of two notices in 2020 indicates that Duncan remains perpetually exposed to energy sector volatility. The absence of any WARN notices filed between 2016 and 2020 does not indicate economic strengthening; rather, it reflects that energy prices remained stable enough to prevent additional major layoffs, a condition that lasted only until the pandemic shock.

Local Economic Impact: Displacement and Structural Adaptation

The displacement of 983 workers in a city of Duncan's size generates measurable hardship. Workers separated under WARN provisions typically face 60 days of notice, after which they must secure alternative employment, relocate, or exit the labor force entirely. In Duncan's labor market, alternative employment opportunities at comparable wage levels are limited. Energy sector workers at Halliburton and related companies typically earn wages substantially above the local median, reflecting the skill requirements and union representation common in oilfield services. When these jobs disappear, workers face either significant wage reductions in alternative employment or geographic relocation.

The long-term community impact extends beyond individual worker outcomes. Population loss accelerates as younger, more mobile workers depart for opportunities in larger metros. Tax bases contract, reducing municipal capacity to maintain infrastructure and services. School enrollment declines. Retail and service sectors contract in response to reduced local spending. These effects propagate throughout Duncan's local economy in a multiplier pattern, with each primary job loss potentially generating 1.5 to 2.0 additional job losses in supporting sectors.

Duncan's economic diversification efforts face structural headwinds. The city has attempted to attract manufacturing and light industrial operations, but these sectors typically offer lower wages and less stable employment than energy services. Manufacturing alone—represented by Haulmark Trailers—has not provided sufficient employment growth to offset energy sector losses.

Regional Context: Duncan Within Oklahoma's Labor Market

Oklahoma's current labor market conditions provide limited buffer against Duncan-scale disruptions. The state's insured unemployment rate stood at 0.63 percent as of early April 2026, with initial jobless claims trending down 1.7 percent over the preceding four weeks and down 10.6 percent year-over-year. The Oklahoma unemployment rate at 3.9 percent in January 2026 indicates a relatively tight labor market by national standards, where the March 2026 national unemployment rate was 4.3 percent.

However, these aggregate figures mask substantial regional variation. Oklahoma City and Tulsa, the state's major metropolitan areas, have developed more diversified economies spanning energy, aviation, healthcare, and technology sectors. Duncan, lacking this diversification, remains a satellite community vulnerable to shocks in its primary employment base. The contrast is stark: while Oklahoma's insured unemployment rate of 0.63 percent suggests strong labor demand statewide, Duncan's actual employment opportunities remain constrained by sectoral concentration. A laid-off Halliburton worker in Duncan cannot easily transition to aerospace manufacturing in Tulsa or healthcare administration in Oklahoma City without relocating, effectively placing that worker outside Oklahoma's labor market statistics despite remaining nominally within the state's borders.

H-1B and Foreign Hiring: Energy Sector Labor Substitution

The H-1B and LCA petition data for Oklahoma reveals minimal direct overlap with Duncan-area employers. The top H-1B employers are universities (University of Oklahoma, Oklahoma State University) and technology consulting firms (Accenture), with certified petitions concentrated in software development and computer systems analysis occupations at average salaries ranging from $54,752 to $107,612.

Halliburton, while not appearing in the top H-1B employer list, is a known filer of H-1B petitions nationally, primarily for specialized engineering positions and project management roles in upstream and midstream operations. The absence of specific H-1B data for Duncan operations does not indicate that Halliburton is not using H-1B workers in its corporate operations; rather, it suggests that the most specialized roles requiring H-1B sponsorship may be concentrated in Halliburton's larger hubs outside Duncan. Nonetheless, the broader pattern across Oklahoma's energy sector—where H-1B usage remains limited compared to technology and healthcare—indicates that layoff decisions are not being made to facilitate foreign worker substitution. Rather, the 2020 Halliburton reductions reflected genuine demand destruction in energy services markets, not workforce replacement strategies.

Duncan's layoff history reflects structural economic vulnerability rather than deliberate labor market manipulation. The city's employment prospects depend substantially on stabilization of energy commodity prices and successful diversification into sectors less vulnerable to global supply shocks.
