Benefits end date after a layoff - 4 weeks in

I am not sure what date my benefits stop after being let go as a procurement assistant. I worked as a procurement assistant before this. I do not want to be surprised by a bill. Did coverage match what HR said?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

Keep a copy of any coverage confirmation in case of later disputes.
