A WARN notice tells you a layoff is coming. For workers aged 40 and older, a second document often arrives with it, or shortly after: a severance offer that asks you to sign away legal claims in exchange for extra pay. That document carries its own deadline, and it is easy to confuse the two clocks. The WARN notice period and the severance review period are different rules, running on different timelines, and only one of them comes from the WARN Act itself.
This article is general information, not legal advice; severance agreements turn on their exact wording, so get independent advice before signing.
The WARN clock and the severance clock are separate
The federal WARN Act generally requires covered employers — those with 100 or more full-time employees — to give 60 days' advance notice of a plant closing or mass layoff. That notice period is about time before the job ends. It does not require the employer to pay severance at all. Severance is a separate offer, governed by the agreement itself and, in a few states, by state law.
The severance review clock comes from a different statute: the Older Workers Benefit Protection Act, which amended the Age Discrimination in Employment Act. When an employer asks a worker aged 40 or older to waive age-discrimination claims in exchange for severance or other benefits, the waiver is only valid if certain conditions are met. The best known is a minimum time to consider the offer.
21 days for one worker, 45 days for a group
For an individual termination, the worker must be given at least 21 days to consider the agreement. For a group termination program — such as a layoff affecting a group of workers, which is exactly what a WARN layoff usually is — the minimum is 45 days. The employer must also advise the worker in writing to consult an attorney before signing.
In a group program, the employer must also provide the job titles and ages of the workers selected, and of those in the same job classification or unit who were not selected. That disclosure lets a worker judge whether age played a role in who was chosen; it is not a finding that it did.
After signing, there is a second window: the worker has 7 days to revoke the agreement, and it does not become effective until that period has passed. So the real decision timeline for a group layoff can run 45 days to consider, plus 7 days to change your mind after signing.
What the clock does not do
The review clock does not extend the WARN notice period, and it does not extend your employment. Your effective date — the date in the WARN notice — stands unless the employer formally postpones or cancels the layoff. A worker can still be laid off on the effective date while the severance decision window is open, and severance is typically paid after the agreement becomes effective, not on the last day of work.
The clock also does not guarantee severance: if no severance is offered, there is no waiver clock to run. (A few state mini-WARN laws, New Jersey's best known, require severance in some cases — but that is state law, not the federal WARN Act.)
Finally, the review clock applies to the waiver of age-discrimination claims, but an agreement may ask you to waive other claims too, and its wording decides what is covered. Read the release paragraph itself, not just the payment figure, before you sign; if it is broad or unclear, that is exactly what the review period is for.
How to use the window well
First, keep the two deadlines on separate lines in your own notes: the WARN effective date, and the severance consideration deadline. Missing the first affects your last day of work; missing the second means losing the offer, not losing the layoff notice.
Second, use the disclosure that comes with a group program: compare the ages and job titles of those selected with those who were not.
Third, do not let the severance deadline rush other decisions: unemployment claims, health coverage, and retirement choices each have their own timelines, none paused by a severance review period. And remember the 7-day revocation right only helps if you use it — revoke in writing, by the method the agreement specifies, if you learn the release covers more than you understood.
The numbers behind the notices
Layoff Atlas currently tracks 681 notices affecting 66,471 reported workers in the last 90 days, with 28 notices carrying no worker count. California leads with 17,715 reported workers, followed by Washington with 17,361, Illinois with 4,385, Texas with 3,280, and Georgia with 2,492.
Upcoming effective weeks total 30,881 reported workers over six weeks: 4,394 in the week of October 31, 4,326 in the week of November 7, 8,453 in the week of November 14, 6,925 in the week of November 21, 5,937 in the week of November 28, and 846 in the week of December 5. These are reported plans, not confirmed job losses: some notices are later postponed, reduced, or cancelled, and coverage varies by state.
If you are 40 or older and a WARN notice lists you, the most valuable thing in your packet may not be the payment figure. It may be the calendar: 21 or 45 days to consider, 7 days to revoke, and a disclosure showing how the group was chosen. Use all of it before you sign.
