The thesis uses analytical prescriptive judicial normative research method. It used the theory of Legal Protection. The data were gathered by using primary, secondary, and tertiary legal materials, supported by approach methods, namely statute approach, conceptual approach and case approach. The gathered data were analyzed qualityatively. The results showed that: First, in the agreement to the contracted work wages between the debtor (private party/contractor) and the creditor (government /employer), the debtor had weaker position compared to the creditor. The debtor is vulnerable to endure loss that was uncertainly paid by the creditor.
