my employer is filing chapter 13 bankruptcy, what can I do to get my sales commission

Your question is really hard to follow. From what I can tell, however, it is not your employer the cabinet company filing Chapter 13, but rather a builder which is one of its customers. This makes sense since companies, such as your employer, are not allowed to file Chapter 13. Chapter 13 is reserved for individuals and individuals who own companies as sole proprietors only. Anyway, you don't have any relationship with the builder so you have no rights in the builder's Chapter 13. Your employer does have a relationship with the builder and should take appropriate legal action to protect its rights. Your rights as an employee are governed by Texas labor laws and you should post another question for a labor lawyer familiar with Texas labor law. The bankruptcy filing of the builder is not relevant to your problem which is a problem between you and your employer the cabinet company.
