Benefits end date after a layoff after 18 years as a project coordinator

I was told my coverage ends on my last day, but the letter says the end of the month. It has been a long 16 weeks. I do not want to be surprised by a bill. Did coverage match what HR said?

I moved my appointments earlier while coverage was active. It saved me a bill.

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