While I understand every aspect of the grievance here, you must stick into your job until you find a replacement.
Unemployment benefit programs pay money to workers who:
Become unemployed through no fault of their own.
Meet certain other eligibility requirements as determined under state law.
Since your case does not satisfy the most basic qualifier,please look for alternative. Talk to a human resource rep in your office,get the issue addressed by a senior executive whom you trust. I am sure there will be a way out since you have dedicated 10 years towards this company.
