What this means for VA workers
Diamond Transportation Services has 4 WARN filings on record covering 970 workers, most recently on May 13, 2026.
WARN Act filings only capture layoffs of 50+ workers at sites of 100+ employees, so smaller reductions, contractor non-renewals, and voluntary separations are not shown here.
Federal WARN Act filings place Diamond Transportation Services on record with 4 notices covering 970 workers, spanning Nov 7, 2025 through May 13, 2026. Because the WARN Act only captures events that affect 50 or more workers at sites of 100+ employees, this count sits at the upper band of the employer's layoff activity — smaller reductions, contractor non-renewals, and voluntary separations are invisible to this dataset. The geographic footprint of 2 states, anchored in VA, in the Transportation & Warehousing sector, shapes which state workforce agencies received the filings and which state-level "mini-WARN" thresholds applied.
Averaging 243 workers per notice, Diamond Transportation Services's filings fall into a pattern that is consistent with site-level consolidation or a multi-department reduction in force. The 4 notices on file represent distinct events, each triggering a 60-day advance warning obligation that fed into state rapid-response systems.
For workers, the practical layer under these numbers is time: the WARN Act's 60-day notification window triggers eligibility for state unemployment insurance, COBRA health-coverage continuation, and rapid-response services from the state workforce agency that received the filing. Workers on VA-based Diamond Transportation Services notices should contact the VA workforce agency directly — response teams, severance negotiation guidance, and TAA (Trade Adjustment Assistance) screening move fastest in the days immediately following a notice. The record above reflects filed notices only; subsequent hiring, rescinded closures, or facility reopenings are not tracked by WARN disclosures.
Diamond Transportation Services has filed 4 WARN Act notices, indicating multiple rounds of workforce reductions. This pattern may reflect industry downturns, strategic restructuring, or regional facility consolidation.
Each notice has affected an average of 243 workers, representing moderately sized workforce reductions. WARN Act notices only capture layoffs meeting federal thresholds (50+ workers) and may not represent all workforce changes.
Diamond Transportation Services has filed 4 WARN Act notices affecting 970 workers across 2 states. The most recent notice was filed on May 13, 2026.
According to WARN Act filings, Diamond Transportation Services has affected 970 workers total, averaging 243 workers per notice.

The Worker Adjustment and Retraining Notification (WARN) Act requires employers with 100+ employees to provide 60 days advance notice of plant closings and mass layoffs affecting 50 or more workers. Not all layoffs require WARN notice.
Workers affected by a WARN-notified layoff may be eligible for unemployment insurance, COBRA health coverage continuation, job retraining through the Trade Adjustment Assistance program, and severance packages if offered by the employer. State workforce agencies often provide additional rapid response services.
Diamond Transportation Services has affected 970 workers across 4 WARN filings in the Transportation & Warehousing sector. The federal WARN Act only captures layoffs affecting 50 or more workers, so actual workforce changes may be larger.
