Upon petition of a debtor for the assignment of his salary, wages, or income to a trustee for the benefit of his creditors, a judge may appoint a trustee, subject to the supervision and order of the court, to receive such salary, wages, or income of such debtor and pay off the obligations due by such debtor as provided in this article, provided that a majority of the creditors have provided written consent of such assignment to the court. If the debtor is employed on a salary or for wages, the written consent of his employer is required.
