When does my employer coverage actually end? after 16 years as a marketing coordinator

I am not sure what date my benefits stop after being let go as a marketing coordinator. I have an appointment next week.

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 5 months ago, and it got easier once I kept a simple log of every call and form.
