Did anyone get a WARN notice? - 12 months and counting

My employer announced that the site will close and gave us written notice. This is my first time dealing with any of this. I do not know if I should start looking now or wait for severance news.

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.
