In my state, in order to keep unemployment you have to prove that you made some sort of action towards getting a job on at least five separate days every week. Also, declining a job offer, no matter how bad it might be, ends the unemployment immediately.
Oh and also we have one of the lowest amounts of benefits and you can only be on for about 24 weeks before they cut you off entirely. Also, they don't pay the first week after you're approved.
