Reading the Diamond Transportation Services WARN Record

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 The record above reflects filed notices only; subsequent hiring, rescinded closures, or facility reopenings are not tracked by WARN disclosures.
