12. ABC Corporation, a legitimate job contractor engaged in the construction business, hired X as a plumber. Under a service agreement, ABC Corporation undertook to provide workers for the construction project of XYZ Corporation, a company engaged in real estate development. X was among those assigned by ABC Corporation to the project. While the construction project was ongoing, X filed a complaint for underpayment of wages against both ABC Corporation and XYZ Corporation. XYZ Corporation denied liability, claiming that ABC Corporation, as the true employer of X, should be solely liable for the underpayment of wages of X. Is XYZ Corporation correct? Reason(s).
