As long as you have a signed agreement with your company then you are a 'creditor' but probably an unsecured creditor as it is usually the banks, finance companies etc that are secured creditors. Make sure you register you claim with the administrators/liquidators, they cannot ignore you but you may only finish up getting a few pence in the pound of the monies owed to you and it could take several years and come in tiny packets. Don't just forget it but don't count on it for your immediate needs either.
