Mare Island Dry Dock, LLC California Layoffs 2025: What Employees Should Know

What the filing says

These are the details as Mare Island Dry Dock, LLCreported them to the state. The EDD publishes every notice, and these figures come from the state's report as retrieved on Aug 13, 2026.

How much notice the law requires

California's WARN Act requires 60 days of advance written notice before a covered mass layoff, and its only statutory exception is a physical calamity or an act of war — far narrower than federal law's three. Who is covered and how the thresholds are counted is in our California WARN Act guide.

Mare Island Dry Dock severance: what to check before you sign

A severance offer is not the notice pay the WARN Act describes. Severance you were already promised — in a contract, a handbook, or a union agreement — cannot be used to satisfy that obligation, though Labor Code section 1402 does let an employer reduce a back-pay award by voluntary payments it was never required to make. A release may also give up more than you expect. Justin reviews severance agreements before workers sign. What to check before you decide is in our full guide to the California WARN Act.

Two things worth doing this week either way. File for unemployment now — WARN money does not reduce it, and the filings here run through Dec 29, 2025, so you do not have to wait for your last day. And keep every document, including the notice itself and anything showing when it arrived.

Questions people are asking

Where a layoff can raise a legal question

A layoff is lawful on its own, and nothing below is a statement about Mare Island Dry Dock. These are the places California law can still come into play, depending on the facts of your own situation.

• The severance you were asked to signA release can give up claims you did not know you had, and the terms are sometimes negotiable.
• How you were selectedA reduction in force still cannot be used to cut someone for a protected reason such as age, disability, pregnancy, or a complaint they made.
• Your final paycheckCalifornia sets when final wages are due at termination, and unpaid time or accrued vacation can carry penalties on top of the wages.
• The length of the notice periodWhere a notice period turns out to fall short of what the law required, the question usually belongs to everyone in the same position rather than to one person.

General information about California law, not legal advice, and reading it does not create an attorney-client relationship.

What has been reported

Press coverage of this layoff, summarized and attributed. This is reporting rather than the filing itself, and we did not independently verify it.

Mare Island Dry Dock notified the City of Vallejo on December 30 that it would close its shipyard and terminate its entire workforce of more than 80 union and non-union employees, citing the loss of a key U.S. Coast Guard contract and unforeseen business circumstances, CBS Sacramento reported.

The San Francisco Chronicle reported that the shutdown followed the loss of an approximately $10 million Coast Guard contract to repair the icebreaker Healy, which was awarded to Vigor Marine Group even though Mare Island had submitted a lower bid; the company's notice to California's Employment Development Department listed 84 permanent layoffs.

CBS Sacramento noted the closure was the second major industrial shutdown announced for Solano County in early 2026, after Anheuser-Busch said its Fairfield brewery would close by February.

  Superior Court of the State of California, County of Solano · A settlement is not an admission of liability.

A PAGA case is not a class action, and there is nothing to opt out of. A PAGA settlement resolves civil penalties owed to the state — most of which the state keeps — and it does not necessarily resolve your own unpaid wages, missed break premiums, or final-paycheck penalties. If you worked here and were not paid correctly, that is a separate question worth asking about. How California wage claims work.
