Benefits end date after a layoff - 22 weeks in

I was told my coverage ends on my last day, but the letter says the end of the month. This is my first time dealing with any of this. The letter is unclear about dental and vision. Did coverage match what HR said?

Ask HR to confirm the exact date in writing. I also called the insurance company to double-check.

Thanks for writing this out. I went through something close to it 14 months ago, and it got easier once I kept a simple log of every call and form.
