Back wages and bankruptcy 

There is no reason to write to the bankruptcy court (in fact, it's completely inappropriate).  If there are going to be assets distributed in the chapter 7 case, you will be notified by the Trustee to file a proof of claim, which you should then do so that you get paid whatever portion is available after liquidation to pay your class of claims.   You have a "priority" claim of up to $10,950 for wages earned within 180 days prior to the chapter 7 case being filed.  You may want to contact the case trustee to see if there will be any assets liquidated.
