Did anyone get a WARN notice? after 3 years as an IT help-desk technician

I received a formal notice about a mass layoff at my workplace. They offered a retention bonus for people who stay. Has anyone been through this?

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

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.
