My question involves unemployment benefits for the state of: Colorado

I was recently (yesterday) fired from my employer of 3 years for a poor decision that put in question my integrity - my employer was unhappy about having to fire me, so they gave me severence, extended medical coverage, and - in writing - stated they would not contest my unemployment.

This is my first time filing unemployement so I am unsure if the state can still deny my claim since my employer is not contesting it. I just want to be prepared because it will definitely put a strain on my finances until I'm able to find another job.

Thanks for any help!
