Did anyone get a WARN notice? after 17 years as a delivery driver

Our team was told about a closure date that is 6 weeks away. I do not know if I should start looking now or wait for severance news. Has anyone been through this?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

Write down key dates and keep copies of the notice. Mine helped when a question came up later.
