Reading the Master Lock Company WARN Record
Master Lock Company's single WARN Act filing in this dataset covers 325 workers, dated Aug 17, 2023. 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, Master Lock Company ranks #43 of 468 tracked employers in WI. Among the 8 other Manufacturing employers with recorded WARN filings, the median is 6,675 affected workers -- Master Lock Company's 325 sits well below that group's typical scale. Every recorded filing was reported to WI's workforce agency, in the Manufacturing sector -- a single-state footprint, unlike the multi-state pattern common among larger employers.
Averaging 325 workers per notice, Master Lock Company's filings fall into a pattern that is consistent with site-level consolidation or a multi-department reduction in force. 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.
Workers on WI-based Master Lock Company notices should contact the WI workforce agency directly, response teams, severance negotiation guidance, and TAA (Trade Adjustment Assistance) screening move fastest in the days immediately following a notice.
