Still, there are loopholes around those labor laws for those tech companies, says Mary Gallagher, a political science professor and director of the Lieberthal-Rogel Center for Chinese Studies at the University of Michigan. Under local regulations or by employers’ digression, employees could be classified as either part of the standard system included in China’s labor laws, or as excluded employees who work seasonally or in white collar jobs where overtime hours aren’t calculated. Gallagher explained, “Localities and employers can abuse the classification system in tech, for example, by classifying even lower level workers as “senior managers.” Then they will work a lot of overtime without additional compensation.”
