Plant closing and notice period questions - 15 weeks in

Our team was told about a closure date that is 15 weeks away. This is my first time dealing with any of this. Some colleagues are already leaving. Has anyone been through this?

Start your search early. I wish I had begun the day of the notice.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
