Regulatory progress and advances of science and technology have improved the efficiency of enterprises. However, instead of freeing ordinary workers from their burdensome labor, they have exacerbated the plight of workers brought about by hidden overtime. Behind this phenomenon, workers continue to bear the burden of work during non-working hours, placing their personal lives in a situation of gradual materialization, and exacerbating the conflict between work and life. The study argues that, under the intersection of capital and technology, statutory working-hour standards and their democratic management are gradually being reshaped and weakened, whilst loopholes in the system actually reduce the level of legal security for overtime. Together, these factors contribute to the proliferation of hidden overtime. The study recommends that legal regulation of hidden overtime should focus on regulating the operation of employers' power, properly address the relationship between democratic management of employees and labor management of enterprises, and determine reasonable criteria for overtime recognition so as to promote work-life balance of workers.
