Plant closing and notice period questions after 8 years as an accountant

My employer announced that the site will close and gave us written notice. This is my first time dealing with any of this. Some colleagues are already leaving. Has anyone been through this?

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

The workforce board ran a rapid-response session for us with résumé help and information on benefits. Ask if yours will.
