Can i get unemployment if i got fired for not renew my cena license and worked five months without knowing they were expired!
You cannot receive unemployment if you were fired. The claim would be denied. Once it's denied you can dispute it if you want.
It is possible for you not to get employment although; it will depend on the individual company. Some people will understand your reasons and give you a job, while others won't even give you a chance to explain yourself.
Hopefully not. If you can't take care of your responsibilities, why should we (tax payers) pay for it?
