Did anyone get a WARN notice? - what worked for you?

I received a formal notice about a mass layoff at my workplace. There are 9 people counting on me, so I am trying to be careful. Some colleagues are already leaving. What did the workforce office offer?

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

I stayed for the retention bonus and looked for work on the side. It cushioned the gap.
