Plant closing and notice period questions, warehouse supervisor here

Our team was told about a closure date that is 17 weeks away. Any experience at all would help. I do not know if I should start looking now or wait for severance news. Has anyone been through this?

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

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