Layoff notice, what does the 60 days mean? after 4 years as a customer-service rep

My employer announced that the site will close and gave us written notice. I have read a lot of threads here and could not find my exact situation. They offered a retention bonus for people who stay.

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

Keep everything in writing and save the confirmation numbers. It saved me later.
