What this means for WA workers
CH2MHill Plateau Remediation Company has 1 recorded WARN filing covering 750 workers, most recently on Jul 29, 2011.
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.
CH2MHill Plateau Remediation Company's single WARN Act filing in this dataset covers 750 workers, dated Jul 29, 2011. A lone filing is the most common shape in the recorded dataset, though the true worker count can run higher (why). By total workers affected, CH2MHill Plateau Remediation Company ranks #49 of 757 tracked employers in WA. Among the 8 other Other Services employers with recorded WARN filings, the median is 3,640 affected workers -- CH2MHill Plateau Remediation Company's 750 sits well below that group's typical scale. Every recorded filing was reported to WA's workforce agency, in the Other Services sector -- a single-state footprint, unlike the multi-state pattern common among larger employers.
Averaging 750 workers per notice, CH2MHill Plateau Remediation Company's filings fall into a pattern that resembles full-facility closures or company-wide restructuring, events that can reshape local labor markets for years. This single notice marks a discrete restructuring event rather than a sustained pattern, though workforce changes below the 50-worker WARN floor may have occurred without disclosure.
