How to collect payment from weeks worked?

You employer is required by Tennessee statute to pay you at least twice a month.  From the information in your question, it sounds like he was behind in payments because a financial institution normally would not refuse to honor a check.  You may request from your employer that new checks be issued.  To the extent your employer was a sole proprietorship, and therefore, upon his passing, the business ceased, you will have a right to file a claim against his estate.
