When does my employer coverage actually end? after 3 years as a line cook

HR said my health plan continues for a bit and I do not understand how. Thank you in advance. I do not want to be surprised by a bill.

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

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.
