US Motor Works files notice to close its Los Angeles parts site

Overview

Updated 52 minutes ago

US Motor Works filed notice with California's Employment Development Department on October 30 to close its Los Angeles site at 3901 Medford Street. The filing lists 19 affected employees and sets December 31, 2026 as the closure date.

A WARN notice is a statement of intent, not a record that jobs have ended. The federal law behind it requires 60 days' written notice, and this filing lands 62 days before the date it names. California's own WARN statute covers layoffs of 50 or more at employers with 75 or more workers; at 19, this filing sits below that threshold, and the notice gives no reason for the closure.

Why it matters

Nineteen jobs end at a Los Angeles auto-parts plant on December 31, with two months of public notice for workers to act.

Scenarios

Los Angeles site closes December 31 as filed

Likely Resolves by Jan 31, 2027

Discussed by: US Motor Works' own filing with the California Employment Development Department

The most direct reading of the notice: operations at 3901 Medford Street end on the date named, all 19 positions go, and the company's other plants in Santa Fe Springs, Georgia, Missouri and Monterrey absorb whatever work remains. Nothing in the public filing suggests a different schedule.

A second notice adds more Los Angeles job cuts

Uncertain Resolves by Q2 2027

Discussed by: No analyst coverage found; inferred from the gap between this filing and California's 50-worker threshold

A 19-person notice from a company that operates a much larger Los Angeles footprint invites the question of whether this is the whole cut. If more positions follow, the mechanism is a further WARN filing, which would appear on the state list with its own date and headcount.

Closure date slips past December 31

Unlikely Resolves by Jan 31, 2027

Discussed by: No public prediction; listed because WARN dates are frequently revised

Employers sometimes extend a notice or push a closure date when a lease, a contract or a customer commitment runs longer than planned. That would show up as a revised filing, a new date on the state list, or a company statement. Nothing in the current record indicates it.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

1988

Worker Adjustment and Retraining Notification Act (1988)

Congress required employers with 100 or more workers to give 60 days' written notice before a plant closing or mass layoff. The law was meant to give workers time to look for jobs or training before the paycheck stopped, rather than after.

Then

Employers began filing notices, and states built lists to publish them.

Now

The 60-day window became the standard disclosure period, and most states, California among them, wrote their own versions with lower thresholds.

Why this matters now

The US Motor Works filing exists on a public state list because of this law, giving workers and local officials a dated record two months before the closure.

2026

California's separate WARN statute (Labor Code 1400.5)

California runs its own layoff-notice law, cited on the state employment department's WARN page. It covers employers with 75 or more workers and layoffs of 50 or more within 30 days, a lower bar than the federal statute, and it requires employers to say how they will connect workers to local workforce services.

Then

More California layoffs land on a public list than federal law alone would produce.

Now

The state list has become the main public record of California plant closures, updated as employers file.

Why this matters now

The Los Angeles filing sits on that state list, though at 19 employees it falls below the state's own 50-worker trigger.
