When does my employer coverage actually end? - first time posting

I was told my coverage ends on my last day, but the letter says the end of the month. It has been a long 16 weeks. I do not want to be surprised by a bill. How did you confirm your end date?

Thanks for writing this out. I went through something close to it 10 months ago, and it got easier once I kept a simple log of every call and form.
