What should I do about the young man who worked with me, and I am unable to pay his wages after the employer refused to pay what is due to me?

It is permissible for an employee to hire another person to perform the work, unless it was stipulated that he must do it himself. The wages of the second employee are binding upon the first employee, not the employer, because they are in exchange for what became obligatory upon him. If you hired him, then his wages are binding upon you, and you sin if you were able to pay him and did not, and if you become insolvent, it remains a debt upon you. However, if the homeowner was the one who hired him, then the wages are binding upon the homeowner.
