Following are some general reasons for which your claim can be rejected:
1. If you have quit your job voluntarily then you will no longer remain eligible for getting the compensation.
2. If you are fired due to some misconduct then you then you will be disqualified for receiving benefits.
3. You must be earning more then some specified amount (mentioned in the Insurance Law) before you are unemployed due to some valid reason.
4. There will be some provisions about removal from job in case if you were on some strike due to some labor dispute. Normally there is certain time period that has to be observed (as mentioned in your state law).
