When multiple claims for damages arise simultaneously in the same case, and when the prescription period for each claim is different, the question arises as to whether the short prescription period of one claim can be diverted to another claim. This recently became an issue in a case regarding the direct employment obligation under the dispatch law. After the Dispatch Act went into effect, when workers who were in an illegal dispatch relationship claimed fulfillment of their direct employment obligations and claimed compensation for damages, the short-term 3-year statute of limitations applicable to wage claims was applied without any question. However, since the regulations deemed as employment were revised to obligatory employment regulations, it became possible to view the violation of the relevant Dispatch Act provisions as non-performance of legal obligations and claim a 10-year statute of limitations. The short-term statute of limitations on wage claims cannot be diverted to the right to claim compensation for damages resulting from a violation of the direct employment obligation simply by asserting that wages were not received as a result of a violation of the direct employment obligation, or that wages could have been received if the direct employment obligation had not been violated. Rather, it is necessary to examine whether there is a substantive and economic closeness between the two bonds. At this time, the similarity between the amount of compensation and the amount of wages, which is the result of calculating damages, cannot be an important criterion for judgment. Rather, practical and economic relevance should be reviewed taking into account the purpose of the legal obligations. Since the practical and economic closeness between the two bonds is only the first step in examining whether the purpose of defining the short-term prescription period is similar, it is natural to reexamine whether the purpose of the short-term prescription period can be applied equally. As a result, it is difficult to recognize a practical and economic closeness between the right to claim damages resulting from a violation of the direct employment obligation and the wage claim. In addition, the purpose of the short prescription period for wage claims does not correspond to the right to claim damages due to violation of direct employment obligations.
