When does my employer coverage actually end? - 5 weeks in

I was told my coverage ends on my last day, but the letter says the end of the month. It has been weighing on me all week. The letter is unclear about dental and vision.

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

Thanks for writing this out. I went through something close to it 11 months ago, and it got easier once I kept a simple log of every call and form.
